Seagate 2.5" Drive Recovery - Failed NAND Chip

We recently had a 2.5" Seagate drive sent in to us which was initially diagnosed as having bad sectors due to the fact that it was spinning but was running slower and slower on the machine to the point where it was not accessible any more. It was also a Laptop SSHD, so sourcing for a matching donor would not be easy since you have to match a certain firmware code which was only available on a certain amount of Seagate laptop drives.

As it turned out, this drive didn’t just have bad sectors, but it had multiple faults (Firmware, electronic and Mechanical).

This is what the engineers had to do with the drive:

  • Firmware was built from 2 ROMs to allow access to the hard drive and correct the errors and the damaged modules that were present on the drive.

  • Then since the NAND chip on the hard drive had failed, a 2nd Firmware had to be built and modified to ignore the failed chip.

  • We also had to perform a head swap on the drive, because once it had started to spin there was a clicking sound coming from it which suggests that there had been a head crash, so we had to find a matching donor and therefore change the heads.

  • Then a 3rd Firmware had to be built based on the other 2 Firmware’s to allow the New donor PCB (which was found in our stock) to be paired with the drive so that it would act as the original PCB.

  • Once the drive is paired then all the engineers had to do was clone the drive, which was an easy process compared to the above. Cloning completed only an hour after the drive was fully recognised. The drive finished cloning with 0 errors and 0 bad sectors.


It was a long process but the engineers stuck with it and managed to recover the data from the drive even though there were many problems with the drive.

SanDisk Cruzer Edge 32GB Data Recovery (Case Study)

SanDisk Cruzer Edge 32GB with Crystal Oscillator
  • Wednesday 13:37 - Client made contact - The client sent a web enquiry that his SanDisk USB stick had been physically broken and contained data he needed to retrieve.

    R3 advised that with physical damage the recovery method was dependant on how badly the break was and where it was, some cases of physically damaged USB drives may need a direct read of the Nand flash chips that store the data.

    The client advised he would like to have a think about it and get back to us at which point he was sent a formal quote by email with his unique reference number.

  • Friday 12:07 - Client accepted - The client wanted to proceed and his device was shipped to our lab in Sheffield from his location in Suffolk. He was advised as per all customers shipping to us to follow our recommendations on packaging.

    The device was to be shipped using registered post to be with us the next working day.

  • Monday 09:15 - Received - The broken memory stick was delivered to us Monday morning at which point it was booked into our DB and the client was advised.

  • Monday 10:02 - Diagnosis and temporary repair - One of our lab engineers diagnosed the device and confirmed the damage to be a clean break of the USB connector (the circuit board was bent but not damaged). The device did have a failed crystal oscillator (on the right side of the image) that had to be replaced.

    This left the device in a temporary working state which allowed an image to be made of the USB stick and backed up on our secure server. In all cases an image of the entire device is taken before the extraction of the lost data is performed.

  • Monday 10:54 - Data backed up and recovery listing sent - After the recovery of any data it is important to reassure the customer their data has been recovered and is safe.

    R3 provide a listing of all the data recovered so that customers can be certain their data is there for verification purposes, it also provides a verification to ensure any files that might be damaged are known about.

    This is something R3 offered free of charge for our customers, other companies often charge for this stage of the recovery process. Another recovery done less than 24 hours after arrival!

  • Tuesday 17:06 - Client confirmation and secure download - The client confirmed he had check the listing of the recovered data and advised he was happy to proceed.

    After the formality of invoice and payment the data was sent back to him by secure transfer so he was able to download straight away rather than having to wait for it to be sent back on a new USB stick.

  • Wednesday 13:30 - Dispatched - Client asked if we would send back a second copy on a new USB stick to his business address in Somerset.

High Priority Data Recovery On A XQD Card (Case Study)

A customer from London working within a company who was developing a documentary film, lost their data through a logical issue with an XQD card. The customer got the train from London the morning of 13/07/2017.

XQD card emergency recovery
  • Job arrived 13/07/2017 14:03PM - We immediately confirmed the customers details and passed the card through to the lab for diagnosis.

  • Diagnosis & Cloning time 14:05PM - 14:35PM - initial diagnosis, placed card in XQD card reader, Engineers isolated all the data that was available, took approximately 20mins to clone it from the card to the lab NAS.

  • Identification of required data 14:38PM - 14:42PM - Lab assistant located the specific files that the customer needed the most, in this case particular footage taken that was integral to the documentary, confirmed with the customer.

  • Data Transfer 14:45PM-15:05PM - Transferred all the data including the priority files to the customers own portable RM HDD. Checked that everything transferred properly.

  • Invoiced for Recovery + Payment and Conclusion 15:10PM-15:35PM - Customer was invoiced the cost of recovery by the sales team and subsequently paid the amount over the phone in the lab. Then took their data on their own RM and left to the train station to return back to London.

This Is one of many examples of high priority data is needed in such a frantic timescale that the customer rushes to the lab, and in this case shows the lab preforming to a high degree in a short space of time and reaching a positive outcome for both parties involved.

The customer was kind enough to leave a testimonial describing the whole situation from her own perspective, you can read it by clicking here.

Emergency Email Data Recovery (Case Study)

A case came into R3 data recovery early one morning with a story along the lines of "laptop dropped need emails ASAP" so we sprang into action.

Deleted emails recovery

The hard drive was removed from the laptop and opened in our cleanroom to find the top platter surface slightly scratched from the impact of hitting the floor but considering the urgency we decided to undertake a head swap and a donor was sourced from our stock.

The head swap went fine with no drama and the hard drive was moved onto our diagnostic machine and powered up for the first time.. After some calibration noises the hard drive decided to behave and the proprietary Firm Ware was backed up and the cloning process begun.

With all data recovery from the technically simple to the multiple head swaps, priority files are always important as a damaged hard drive may only have a short life after such an accident so focussing on these files maximises the results in these circumstances.

In this client's case the email file was cloned the best possible considering the scratches and late that night the finished email file was uploaded.

A Customers Perspective: Extreme Anxiety to Elation in 48 Hours

I am a fashion photographer and I was on location shooting in Italy when one of my hard drives with my current work got damaged. It was showing the catalogue and list of names of the folders but not showing any of the images inside those files but still showed that I had used 500 GB of storage.​

I tried it in any computer and MacBook (It is a mac hard drive) I could get my hands on. I then started to panic because the computer would freeze when I tried to open it and on some computers it wouldnt read the hard drive at all.​

R3 Emergency Recovery Specialists in the UK

In a crying panic frenzy I googled data recovery UK and found an emergency number for a man called Andy Butler at R3 Data Recovery who soon became my favourite person in the world.

I was ever so slightly hysterical on the phone and he managed to calm me down and got me to explain what had happened and explained that it was likely to be an issue with the signalling between the catalogue and the data itself.​

I wasn't due back in the UK for another 4 days and was trying to think of what I could do or how I could get the HDD to him before then. I decided to book an emergency flight home the next morning because I couldnt sit and do nothing, especially not knowing how serious the situation could be.​

I flew to London and got a train straight to Sheffield where I was met by Andy and his charming driver who took me straight to their lab where I promised not to cry or touch anything and sat in the corner hoping they could work their magic. They sent me off for a few hours and said they would call me hourly with an update.​

I have to state that I initially called him on a Saturday night in a mess emotionally and this was Monday morning so I was like most creative people I know, quite last minute but he made time for me.

He told me there was a problem with the heads of a hard drive (I gained a lot of knowledge of the ins and outs of data and hardware that day) and they were replacing them with other heads and coding to try and talk to the data.​

Long story short after a couple of tantrums, lots of tears, travelling over 2500 km Andy and his team of geniuses managed to rescue all of my images in one day and they were all in order and in the correct files (I have been told sometimes when rescuing data it can get mixed up and in the wrong order/ folder).

I put all my work and faith in his hands and he didn't let me down and was completely charming and wonderful from start to finish of my mini meltdown data lost and found experience. What a brilliant man. I am so happy I found R3 data recovery but in the nicest way possible I hope I won't have to see them again too soon and that my technology will all be ok and my backups wont fail!

It did cost me £1000 (because I needed 2 new hard drives and I needed it all doing in 1 day and most people allow 7-10 days) but you can't put a price on your career and other clients work and it was worth every penny. I am so very grateful that he went above and beyond to help me and was at the end of the phone with every question I had.

Vintage Macintosh Data Recovery (Case Study)

At the R3 lab this week we had a 25 year old Macintosh delivered, which is older than half of our employees. It contained a 120MB SCSI drive which in comparison to today’s hard drive has a miniscule storage capacity and relatively dated components. However this doesn’t make the task of recovering the hard drive any more easy.

Vintage Macintosh Data Recovery

First of all the interface on the drive was extremely old and due to the influx of jobs that we have that are predominantly modern hard drives and RAID arrays, we didn’t initially have the required SCSI adapter for the interface. After locating the adapter that we needed online and subsequently ordering it we awaited its arrival to the lab.

As the 25 year old SCSI drive that were housed inside the Macintosh were virtually exclusive to U.S sellers in terms of sourcing for parts, the adapter for the drive took over a week to arrive as it was sent from California. Once the adapter arrived it was passed to the engineer who had authority over this specific job and the cloning process of the drive was started. The drive only took a 20 minutes to clone as it was an extremely small capacity drive in comparison to modern HDD’s.

Once the drive was cloned it was passed for file listing and between the lab assistants and the sales team it was copied to an RM and the customer received the file list and was invoiced for the work. And ultimately everything ended on a positive note, showing that no matter how old or how unlikely a good chance of recovery a job may have, the R3 Team strives to make a successful recovery a reality. In this case that recovery was 25 years in the making.

64GB Emergency SD Card Recovery (Case Study)

A customer who is from The Netherlands contacted us about a faulty SD card. The issue was that he had some trouble accessing the Card that was in his camera, it didn’t help that the device was full which prevented him from saving any more images to his memory card.

After a quick assessment and quote by phone he soon brought his SD card into the lab, as well as an external drive for the recovered data to be transferred to.

Emergency SD Memory Card Recovery

The Data Recovery Process

29/11 at 17:25pm - The customer sent in the SD card at 14:12pm, and after 3 hours the engineers managed to find the data and copy it to the customer’s external drive. The problem with the SD Card was a electornic fault on the printed sircuit board, the engineer had to do some tricky soldering to get the device working again.

30/11 at 10:09am - The customer’s data was copied to his external drive and a file listing of the data was also sent to him by email, this was so that he could check to see if the file headers were ok. (Screenshots were also sent due to the files being CR2s which had no distinctive file names).

4/12 at 16:20pm - The customer then paid for the recovery and came down to pick up the external drive with the recovered data on it, he was very satisfied with how we handled the recovery and said that he would definitely recommend us.

Emergency 4TB Seagate Barracuda Recovery (Case Study)

A customer called us up to discuss a couple of 4TB Seagate 3.5" drives. The customer explained that he can't read anything from the hard drives neither can load them up successfully, and further mentioned that both drives had the statement:

You need to format the disk in Drive "blank": before you can use it.

This suggests that the drives both have bad sectors and that it is not the best idea to keep powering up the drive or the amount of bad sectors will accumulate leading to more problems with accessing the drive and data.

SEAGATE 4TB HARD DRIVE

The Data Recovery Process

07/09/2017 13:01pm - Both Drives Quoted and Awaiting Arrival of devices - The customer had been quoted a reasonable price (for an emergency service) for both drives and it was a case of the customer arranging a collection so that the drives would be sent to us. We also stressed that the customer packages the drives well to avoid any physical damage to the drive inside and outside.

08/09/2017 10:34am - Received Drives - The drives had arrived the day after the customer accepted the quotation. We immediately booked in the drives to the database, picked a couple of image drives from the image cupboard and sent them through to the lab to be diagnosed.

08/09/2017 13:38pm - Diagnostic and cloning - At this point the drives had been booked in and the drives were diagnosed. There were a couple of SMART errors on both drives and also there were some firmware corrections that had to be done, but the reality was there was not too much wrong with the drives. After the problems had been corrected we could safely put both drives for cloning.

09/09/2017 11:21am - Cloning completion and Data Transfer - By this time both drives had finished cloning. The first drive finished with 6 bad sectors and the second drive finished with no bad sectors at all. It was now a case of transferring the data to a couple of 3TB external drives.

11/09/2017 17:05pm - Transfer completion and Awaiting Payment - The data from both drives finished copying to the external drives on 10/09.

14/09/2017 11:18am - Payment complete and Drives dispatched - Payment was received and both sets of data were sent out to the customer.

To conclude, given that there was a lot of data to clone and transfer, we managed to recover the data fairly quickly and on top of that get a satisfactory review from the customer.

iPhone 5S Data Recovery (Casey Study)

At R3 we get more than our fair share of recoveries, but recently we have been sent more phones/tablets due to either being dropped or water damage.

As for this job in particular, the customer sent in her iPhone 5S. When we saw that the screen was badly damaged we knew that it wasn’t going to be an easy recovery.

iPhone 5S damaged screen recovery

Upon further inspection, the engineer dealing with the phone found that as well as the destroyed screen, there were components that were out of place, the chassis was twisted, the battery was swollen and the logic was damaged since the Firmware recovery tool was identifying a lot of errors. The engineer also mentioned that it looked like the phone had been driven over.

It seemed like there was nothing more that we could do, we were weighing our options and to potentially get a recovery we found that we can recover data from the client’s iCloud account if we have the customer’s iCloud login details. So once the customer gave us the details, we were able to extract the data from the iCloud backups and iCloud shared photos, and we were therefore able to produce a File listing of the data.

So in short, since the customer only wanted iCloud photos and videos we didn’t need to actually try and repair the phone since we obtained the customer’s iCloud details and extracted the data from iCloud.

The recovery process took 3 days to complete which was well under the standard service time frame (7-10 working days).

EMC SAN RAID 5 Disaster Recovery Alert

An unknown number of EMC Storage arrays could be a ticking time bomb in the event the data on them is not backed up elsewhere.

An obscure bug in an EMC RAID controller is a rare discovery for any data recovery engineer but the team approach by R3 achieved a recovery that very few data recovery labs in the world have ever seen let alone recovered successfully.

​This is of interest and notable because most Dell / EMC technical / disaster recovery support engineers would just declare the data corrupt and unrecoverable, restore from a backup and not realise it is possible it will happen again.

EMC RAID Storage System in the Lab at Secure House Sheffield

​Cloud Backup Gone Wrong​​​​​​​

​A problem with a cloud backup meant that the only chance of saving months of work from being lost was to call a data recovery company.

R3 initially lost the job to a substantially cheaper / high risk data recovery / computer forensics investigators. The client did subsequent investigations and elected to retrieve the server from the competitors HQ in Wales and drive it direct to Security House in Sheffield.

The 15 Disk RAID 5 configuration included 1 hot swap disc, but 2 of the Seagate FC series fibre channel discs had failed.

The recovery was complicated at a number of levels but in summary:

  • A disc had failed
  • A hot disc did not work
  • Another disc failed
  • The resync to the hot disc failed in some unexplained manner

The discs were formatted 520bytes per sector which was common for enterprise class SAN but data recovery algorithms / software are most stable working with 512byte per sector formatting.

The client contacted a British / Global data recovery company who were unable to diagnose the problem or propose a solution and R3 were called to take over the case.

On the face of it solving the disc failures, imaging conversion, VMFS and recovery of specific data from within just 1 of dozens of VMs was complex enough.

But as the tasks progressed something was wrong and it just did not make sense.

During any disaster / failure there are a number of factors​ - each year I manage several of the larger disasters in UK and dozens of relatively routine for the R3 team recoveries with disc arrays in pools from as little as 4, 6 12, and others with 24, 55, 180 and recently a pair of 240x 4TB SAN with varying RAID combinations and Tables.

But this EMC RAID 5 was different, it not only had a very seriously degraded disk which had sustained a head crash but the resync had written as data not parity and prevented the data from the RAID being accessible.

In fact it prevented a RAID recovery being possible. R3 engineers were initially stumped because the last disc to fail was proving difficult to get a full image from and took a few days in itself to be recovered and its image converted to 512bytes per sector.

The first to fail disc initially was ruled out as one of the discs being needed because it was out of sync by several weeks.

But on rebuilding the RAID5 volume the VMs were showing as corrupt and all involved including the developers of RAID recovery software and hardware could not help and hit a dead end.

Later we realised just how unique this EMC failure was and that no one had identified a similar case ever.

EMC now part of Dell is "fairly good gear" R3 have worked on a number EMC data recovery cases where multiple disc failures have caused the data to be inaccessible but non that effectively wrote back to a RAID5 disc member in RAID0.

All involved had never seen anything like this on an EMC or on any hardware for that matter.

After solving this a bespoke system configuration was built and a script developed. All VMs were extracted in order of priority and the contained data extracted and tested by the client.

Apart from the normal server dirty shutdown problems needing some database file repairs it was a full recovery.
