Since the late 2001s, nerdcore computers service centre has performed recovery procedures on tens of thousands of Seagate desktop and laptop drives. Seagate introduced many modern innovations in data storage technology, and while their drives are reliable overall, our knowledge of some recurring issues allows for an easier data recovery process.
Early Seagate drives (including models introduced from the late 1990s to the mid-2000s) frequently encountered spindle issues – a problem that has been largely corrected in recent generations. Spindle seizures could suddenly prevent drives from operating, and our engineers perform full platter replacement procedures to recover data from these early models.

Basic Seagate Hard Drive Failure Modes The basic failure modes of a Seagate are listed below. We recommend contacting a qualified Seagate data recovery company if any of these issues are present:
Bad Heads – Seagate drives with bad heads will spin up and click several times, then power down. This issue is often caused by physical damage.The data recovery procedure will include replacing the heads in an ISO 5 clean room environment, turning off auto reallocation and media cache if applicable so that the drive can be cloned. We will often need to use firmware repair equipment to complete this type of recovery.
Service Track Damage – Seagate drives with service track damage will spin up and will likely sound healthy. The spindle operates properly and will continue to spin, but the drive may not be recognized by the system BIOS (or equivalent). If it is recognized, it may display an incorrect model number, serial number, or size attribute.Service track issues are fairly common in the Seagate drives that we receive. The data recovery process will vary depending on the drive family. For example, a Seagate 7200.11 service track issue would require an entirely different fix from a 7200.12.In our experience, 7200.11 drives generally had problems with the defect lists and the translator, while drives from the 7200.12 family can get hung up on sections of the microcode. These issues can usually be fixed by turning off auto reallocation and media cache with special equipment. In any case, we would perform a free evaluation to provide a quote before deciding on an appropriate data recovery technique.
PCB Failure – Seagate drives with electronic/PCB issues may not spin (the spindle does not engage when the drive is connected to a power source). The data recovery process will often require the removal of damaged diodes. Our engineers may also need to swap the ROM to a new printed circuit board. This process requires extremely specialized equipment, including firmware repair tools, and should never be attempted outside of a data recovery laboratory.
Stuck Write Heads – The drive will not spin and will emit a repetitive low pitch buzzing noise. Ideally, this will be fixed by opening the drive in a cleanroom and moving the heads back to the landing zone/ramp. If the heads are damaged, they will need to be replaced with an adequate donor.
Seized Hard Drive Spindle – The hard drive will not spin and will emit a repetitive low-pitch buzzing noise. This is rare on newer Seagate drives. The data recovery process will include a full repair of the spindle or a complete platter swap to an adequate donor. This type of failure is normally caused by physical abuse/dropping.
Other issues may occur, and we highly recommend seeking a professional Seagate data recovery company if you notice any of the failure modes listed above. Never attempt to open a Seagate hard drive outside of a cleanroom, as this may permanently damage the drive.

Nerdcore computers service centre laboratories are equipped with advanced microcode repair tools, which allow our engineers to quickly recover data from most Seagate drives. In many instances, we also need to repair failed read/write heads and other components in a Class 5 clean room in order to get a full copy of all of the files on the disk. We offer high success rates for all Seagate models, and all of our laboratories are equipped to handle these cases. Signs of Failure for Seagate Hard Drives
Seagate hard drives can present a wide number of failure symptoms, and some drives might display a few different symptoms simultaneously. To completely diagnose the damage, you need a professional data recovery evaluation. Hard Drive PCB
Many Seagate data recovery cases require PCB repair.
The following symptoms can accompany physical failures:
Clicking Noises Drive Doesn’t Spin Extensive File Corruption Hard Drive Displays Inaccurate Specifications (Free Space, Total Size, Etc.) Hard Drive is Excessively Hot to the Touch Computer Cannot Detect Drive
If you notice any signs of media issues, turn your computer off and refrain from operating your hard drive. Don’t run firmware utilities, data recovery software, or any other applications. Call 1300 637 326 to speak with a Seagate hard drive data recovery expert from Nerdcore computers service centre.

SSD NAND chips and controller on PCB close-up photoSolid-state drive (SSD) technology has progressed in terms of reliability, but it’s far from perfect. When you can’t read files on your device, you need an SSD data recovery company that understands the complex architecture of the format – and for the best results, your case needs experienced engineers and state-of-the-art technology.
At Nerdcore computers service centre has offered services for solid-state drives from around 2001, and we can capably recover data from modern consumer devices and legacy media after any type of failure. All of our laboratories are fully outfitted for solid-state drive recovery including different interfaces and form-factors such as SATA, mSATA, M.2, PCIe, etc.
Call 1300637326 to get started or learn more about our process below.
Our Process for SSD Data Recovery
SSD data recovery is very different from hard drive data recovery and requires completely different tools. Whereas hard drives store information on magnetic materials that physically move, solid state drives don’t have any moving parts. They’re much faster than hard drives, but they’re also subject to memory wear and physical damage. This means that while SSD is reliable, it’s not perfect, and engineers need to use a specialized process to recover corrupt or deleted files.
The basic process for SSD data recovery starts with an evaluation. We provide a free price quote, which ranges depending on several factors. The most important factor is whether the case is considered a Level 1 or Level 2 recovery:
Level 1 Solid-State Drive Recovery – At this level, the SSD may require minimal physical repairs, but most repairs will involve the firmware of the drive (accessed using hardware developed within the nerdcore computers service centre research laboratory). We may also be able to access the SSD and fix corrupt files with software. We perform an image of the drive using the drive’s intact controller, but we do not remove the chips that store information (the flash chips). Level 2 Solid-State Drive Recovery – These are more severe recoveries with noticeable physical damage or electronic damage. We will need to remove the memory chips, create a raw dump of each individual chip, and then apply the wear-level algorithm, which the SSD uses to prevent premature memory wear (more information on wear leveling can be found on this Wikipedia page). We usually identify data structures to determine the wear-leveling algorithm; this is often a very difficult process, but our success rates are still high.
In either case, we will use special tools and software to read the information and to create a usable copy of any files on the device. It is important to note that most solid-state drives do not have user-serviceable components, and we strongly recommend sending any damaged SSD to a qualified data recovery center.
Intel 525 Series mSATA solid state driveCommon SSD failure symptoms include slow transfer rates, repeated file access issues, file corruption, and a large number of bad sectors. Solid-state drive issues are often progressive, which means that they become worse as the drive continues to operate. Because of this, we do not recommend running data recovery software on an SSD. You should shut your drive off if you encounter any of these issues or if you lose data due to file deletion or software error.
Our SSD data recovery services feature: Support for All Solid-State Drives – Nerdcore computers service centre offers services for both SATA and PCI Express-based solid state drives from Samsung, Crucial, Intel, Toshiba/OCZ, Kingston, and dozens of other manufacturers. We also offer services for traditional hard drives and hybrid HDD-SDD devices.

Hard Drive Data Recovery is our passion and helping people is our mission. If we can’t recover it, no one can. At Nerdcore computers service centre we had been given the chance to offer in the 2001 as an authorized repair center for Seagate, Conner, Quantum and Mini Scribe hard drives. Today we continue to focus on hard drives. We service almost 3000 assorted hard drives every month and have successfully recovered data from virtually every model of hard drive manufactured for the personal computer.
Our biggest advantage for hard drive recovery is having a massive largest inventory of used hard drives on-site. Because we do not have to buy parts drives on the open market like our competitors, we can afford to use more parts and try harder. This results in greater successes with physically crashed hard drives. We will attempt recoveries (many successful) that others deem unrecoverable.
Having almost free parts also allows us to keep our fees lower as we don’t have parts and shipping costs to pass on.
Turnaround time can be kept to a minimum as we don’t lose time waiting for parts drives to be shipped to us. This also allows us to perform emergency after hour recoveries while our competitors must source and order hard drive parts. Nerdcore computers service centre Hard Drive Data Recovery expertise is recognized industry wide, and in particular, our abilities to recover data from physically crashed hard drives are unrivaled. In fact, we do many of the more difficult data recoveries for several data recovery companies.
Our ISO 9001 certified processes and facility have been created with hard drive data recovery in mind. We maintain a class 100 clean-room environment for all head replacements as well as following stringent ESD procedures.
Security for your sensitive data is a no brainer at nerdcore computers service you can rest assured we will get all your data returned to you the way it was.

Staring ahead at the computer screen, anxiously awaiting a web page
to load, you finally admit maybe there’s a problem with the computer.
The computer is only six months old, so there’s no reason a web page
should take 30 seconds to appear. Maybe there’s a problem with the
software that’s causing delays.
Then you realize that Adobe update you clicked on a few weeks ago may not have been from Adobe.
Web-based malware is often the culprit for computers running slower
than normal. Oftentimes users don’t realize malware is on their Mac or
PC until they’re taken to websites they don’t recognize, their search
engines change or their computers slow down.
Users can find and fix malware problems on their own, for free. But sometimes users prefer to call computer repair professionals to fix these and other problems.
“It’s really more of a personality question versus their skills,” says Nick Veloutsos, owner of Nerdcore computers Services in Hughesdale
What is malware?
Malware is any program installed on a computer that doesn’t belong.
Most malware lands on computers when users click on legitimate-looking
pop-up icons telling them to update their software, Nick says.
Often malware will make subtle changes to your system, including
adding attachments to your web browser’s toolbar, or changing your
homepage. While these may seem innocuous, the more malware your computer
gathers, the slower it runs.
“The more of those little things you have, the slower your computer
will get, and the greater the chances that things are going to go
wrong,” Nick says.
Removing malware
Users can eliminate malware themselves if they’re confident enough to navigate a computer’s settings.
“It’s going through the program list and removing what doesn’t belong,” Nick says.
But Jones also has clients who aren’t comfortable altering their computer’s settings, largely out of fear of breaking something.
The cost of hiring a computer professional
varies by provider. Jones charges $120 per hour, though sometimes
during service calls he’s also able to answer questions and solve other
tech-related problems for clients.
Hiring a computer repair professional
If you do hire a professional to check your computer’s software, it’s
important for them to physically be on-site to check your system.
Service providers can use software to access your computer remotely,
without ever setting foot in your home. But because there are multiple
forms of malware it’s nearly impossible to provide a one-size-fits-all
solution for a slow computer. Technicians should also physically check
the computer to make sure there aren’t signs of larger problems, such as
a fan that never stops running, Nick says.
That’s difficult to do without ever leaving the office.
“You’re basically fighting with one hand tied behind your back,” Nick says.
Computer hardware problems
Not all computer problems are software related. If your computer won’t turn on, chances are you have a hardware problem.
Hard drives are the most common and practical computer parts to
replace. The equipment costs between $60 and $100, and the job takes
about two hours. Jones says replacing a hard drive is roughly a $300
job.
Before paying for a hardware repair, consider the age of your
computer. If you have a six-year-old computer that needs several hundred
dollars in new parts it might be time to buy a new one.

When it comes to network traffic, it's important to establish a filtering process that identifies and blocks potential cyberattacks, such as worms spreading ransomware and intruders exploiting vulnerabilities, while permitting the flow of legitimate traffic. In this post, the latest in a series on best practices for network security, I explore best practices for network border protection at the Internet router and firewall.
Before we begin exploring best practices, it is important to note that these recommendations are geared toward large organizations and government agencies and would not likely be appropriate for a home network or very small business network. For example, in a small business or home network, the firewalls and routers might be collapsed into one device. This post will primarily focus on larger, enterprise networks where the Internet router and firewall are broken out into distinct devices, as shown in the figure below
It is also important to note that this post will primarily focus on filtering of inbound traffic. Filtering of outbound traffic is also very important for organizations and will be the subject of a future post.
Let Your Routers Route
The philosophy of many network administrators is let your routers route. In a larger network with specialized devices, you want to let the Internet router do its primary job, which is to pass traffic. Having said that, there are exceptions where traffic/security issues will require some basic blocking on the Internet router. Here are some principles to keep in mind:
Don't add an access control list (ACL) entry for every suspicious IP address. I once worked for an organization that would add an ACL entry to the Internet router every time it saw an attempt from outside to do something suspicious, even if that attempt was blocked by the firewall.
The problem with this approach is that it creates a massive ACL. The Internet router now has to process every entry in the ACL when filtering traffic. This approach also makes it hard for people who manage the ACL, because network administrators must determine why a particular entry was added to the ACL, and whether that entry is still needed. Additionally, for devices that process an ACL in order from top to bottom, a longer and more complicated ACL makes it harder to be sure you've placed new entries in exactly the right place.
Protect the devices inside the border router and outside the firewall, and the outside interface of the firewall. People often forget that there are vulnerable devices sitting outside the firewall, including the Internet router itself. There is usually no reason for someone outside your network to access the devices outside your firewall. It is important to have filters on the router to prevent unauthorized users from being able to log in to the router, or to send management traffic to the router.
For devices between the Internet router and the firewall (like the switch in the diagram above), the easiest way to prevent access from the outside is to use non-routed RFC 1918 address space. A device with private addressing can't be reached directly from the Internet. That said, if you're protecting a network that already has public, registered addresses on internal network equipment (it happens), it's absolutely critical that you create ACL entries on your Internet router preventing access from the outside to your network equipment addresses. Remember to include the firewall's outside interface (if using public addressing on it) as well. If, for some reason, access to these devices is needed from the outside, you should permit only the specific source IP address and protocol needed.
Out-of-band (OOB) management offers another option for reaching your border router, or other network equipment, from the outside. If you are using an external company to monitor your infrastructure, the external company should be able to provide you specific IP addresses and protocols. You can allow those and block everything else.
Filter the bogons. The bogons list represents an entire class of private and reserved IP addresses.
According to Team Cymru, which maintains the most up-to-date list of bogons, "a bogon prefix is a route that should never appear in the Internet routing table. A packet routed over the public Internet (not including over VPNs or other tunnels) should never have a source address in a bogon range. These are commonly found as the source addresses of DDoS attacks."
While we don't want to make the Internet router act as a firewall, the bogons list represents a simple way to eliminate obviously bad traffic at your network border, without the need for deep inspection, checking state tables, or complicated ACL entries.
If you're filtering bogons, however, it's important that you keep your filters up to date. The bogons list can change as previously unallocated IP addresses are allocated by the Regional Internet Registries (RIRs).
Block inbound traffic sourced from your own IP addresses. At the Internet router, it is important to block any external traffic that is sourced from an internal IP address. For example, if you have your own allocated block of addresses, you should not see external traffic sourced from one of your internal addresses. If you see traffic sourced from your own internal IP space trying to enter your network from the Internet, it suggests either that someone is spoofing your addresses to try to do you harm or a routing problem has occurred. It is important to block this type of traffic at the Internet router because it is very possible that traffic allegedly sourced from your internal IP space is only subject to limited filtering once it gets to your internal network.
In summary, when considering filtering at the Internet router level
Don't mess with intricate filtering systems to block every suspicious IP address.
Focus on blocking bogons and anyone trying to spoof your IP addresses.
Protect the Internet router from outside traffic, and protect anything that sits between the router and the firewall.
Let Firewalls Be Firewalls
At the firewall level, your approach to filtering should be more fine-grained. As with your border router, first and foremost it is important to lock down access to the firewall itself. Unauthorized users should not have access to this device.
In addition, there are two principles for filtering at the firewall level:
Default deny. A firewall is a security device and is designed to protect your assets. Your default position when configuring the firewall should therefore be to deny traffic. Don't think of the firewall as the device that permits all traffic through, except for the things you want to block. Instead, think of your firewall as the device that blocks all traffic, except for those things you choose to permit.
Label everything. With firewall filtering, it is important to assume that someday a new firewall administrator will have to figure out what you did and why. I have seen incredibly complex firewall rule bases that were hard to understand because the logic and reasoning behind them were unclear (e.g., IP addresses in rules with no indication of what devices the IP addresses represented, with no labeling to tell you why the traffic was being permitted or denied). When it comes to firewall filtering, every new rule should take into account that a future firewall administrator must one day read these rules and understand them.
When you are creating new rules to permit inbound traffic, try to be as specific as possible. For example, if you know a particular server requires inbound traffic on just three TCP ports, don't create a rule permitting all inbound TCP to that server--create a rule allowing only the needed ports. While it may be easier to make the rule less specific "in case we need to permit more ports later on," this opens up that server to all sorts of traffic that it shouldn't be receiving, including malicious traffic designed to exploit vulnerabilities on all those TCP ports you left open.
Sometimes when a new server or application is being brought online, I've seen people say "We aren't sure which protocols are needed--just permit everything for now and we'll lock it down when we know exactly what we need to permit through." In my experience, that later lock down never happens. Think carefully about whether you want to put a device on your network without knowing exactly which protocols it's supposed to be using, and then allow traffic on any protocol to reach it.
At the same time, while you're being as specific as possible with your rule set, there are best practices you can use to make it easier on yourself. If you create an object group in your firewall to include the IP addresses of all devices of the same type, with the same security requirements (e.g., all your web servers or all your email servers), you can create a single rule permitting all the specific ports and protocols needed to the entire group of servers at once.
Similarly, if there's a particular service on your network that you need to permit a known set of external IP addresses or networks to access, you can create an object representing all of those external addresses and networks, and then create a single rule allowing those external devices access to the needed service. Remember the rule about letting future firewall administrators understand what you did and why you did it? Label that object so it's clearly understood what those addresses represent (e.g., "External B2B Partners" or "Remote Office Admins"). Moreover, if you are able to add comments to your rules, add a comment that explains what the rule is for, and whether there is an expiration date for that rule.
Finally, it is important for the firewall administrator to conduct a regular--at the very least annual--audit of firewall rules. Ideally, you would have the documentation and rule change requests in one file to ensure an easier audit. Rule requesters should be asked to verify that the rule they requested is still required, and unneeded rules should be removed.
To recap, when it comes to firewall filtering, it is important to
Ensure that your default position is to deny traffic, not to permit it.
Label everything as specifically as possible.
Conduct regular audits.
By taking a layered approach to network border filtering, you can block the most obviously bogus or potentially harmful traffic at your Internet router, while allowing the firewall to do what it's designed to do, and inspect and block the remaining threats.
Wrapping Up and Looking Ahead
As attacks become more sophisticated, our team of network analysts at CERT increasingly finds Internet-facing services that aren't well deployed within a network. As Mark Langston wrote in his recent post on DNS Best Practices, many of these services make up the foundation for the security and operation of internal and external network applications.
This article is the latest in a series of blog posts offering best practices for these foundational structures.

As computer viruses and spyware are becoming ever more technical, eradicating them isn’t as easy as simply adding or removing programs.
Instead they can disable your existing antivirus software, fill your screen with pop-ups, add toolbars you don’t even want, mysteriously change your trusted home page to a shopping website, and even stop your PC from working altogether.
In essence they can be seriously debilitating.
This is where our Nerdcore techs can help. Our dedicated team are experienced in removing all types of:
Leaving your desktop PC or laptop as good as new. What’s more, in most cases all of your data remains intact too. At Nerdcore computers we use the latest digital tools to scan your PC for viruses and remove all traces of any infections. In some cases when viruses are unable to be removed, we’ll often carry out a fresh install.
Whatever it takes, we’ll make sure your PC is virus or spyware free. Here’s a little more information about the types of problems that can occur.
This is the latest type of problem to hit cyber-space and is usually initiated by cyber-criminals looking to extract money. Some of the most recent types of ransomware to hit Australia are the Cryptolocker and Ukash viruses.
Typically a user will log into their computer/laptop and after the regular start-up screen they’ll see a notice stating that either all files have been encrypted or the computer has been remotely locked. In either case, criminals will demand sums of money to release the problem, usually in the region of $100 – $600 AUD. Hence the name ransomware.
In essence, viruses are software programs written by individuals that are designed to be spread from one PC to another. They attach themselves to your files, applications, or operating systems. Most are simply annoying, utilising pop-ups, but in some cases they can be damaging, deleting key files and/or encrypting any documents you have.
This is a broad term which equates to any spyware, trojans, ransomware, worms, adware or virus. Malware is usually carried in free software which the user intentionally downloads and normally disrupts the computer’s operation. This makes your machine difficult, if not impossible to use.
This is software that’s been inadvertently installed on your computer and is designed specifically to capture data. It may be something as innocuous as a list of the websites you’ve visited, but in extreme cases criminals can gather sufficient information to capture keystrokes that might give away passwords to bank details and bank accounts.
As the name suggests browser hijackers automatically modify your web-browser settings and make changes without permission. Often it replaces an existing home page or search engine page with its own and is used to force hits to a particular website. Most browser hijacking is relatively easy to reverse, but some can be more tricky.
