Old Industrial Equipment Data Recovery

Old Industrial Equipment Data Recovery

It’s always interesting to see how a complex manufacturing line can be run from such old hardware. In this case we were sent a custom PC from a  machine that is used to fill and cap bottles.

The first problem was trying to get the case open to remove the hard drive. There is no ifixit guide for this thing!

Inside I found a 20GB Seagate laptop drive (dated 2007) running Windows 2000 along with the programs that control the machinery. The hard drive was connected to a proprietary motherboard that in turn connected to the machinery via serial ports.

In this case, data recovery was not enough. What the client needed was a full working copy of the failed disk to reinstall into the system. The aim was to get the kit up and running and return it to the customer so they could carry on with work as soon as possible.

We’re set up to handle exactly this sort of problem, so I got this recovered and returned within two days.

Seagate Barracuda Ramp Weakness

Seagate Barracuda Ramp Weakness

During a recent RAID 5 recovery attempt, John made an interesting discovery inside the two failed disks. The plastic ramp that the heads park onto when idle had snapped in the same position on both drives. We don’t know if the heads got damaged first, and then broke the ramps during parking, or if the ramps broke first, damaging the heads as they parked. The client told us the disks were not dropped or jolted. Whatever the cause, both disks had scratches to the delicate magnetic surfaces. In this case, two failed disks from a four disk RAID 5 means the data recovery is not possible.

Old vs New

The other two disks in the RAID had different firmware and don’t show the same fault. We don’t know if these disks have the other (older?) more robust ramp system that we’ve seen in similar disks.

These ramp problems are the latest in a long line of faults for Seagate.

Interestingly, the surviving disks in this RAID array were dated 2013, and the failed disks 2014. I would have expected the older disks to fail first.

SandForce SSD Data Recovery Problems

Mac Pro SSD

The low prices and high speed access of the Sandforce controller made it an appealing option for SSD manufacturers such as Toshiba, Intel, Kingston & OCX. But it soon became a problem for users when the SSD devices using these controllers started to fail in their computers after just six months of use. Usually it resulted in the device not being recognised by the computer bios, and not functioning at all.

That was okay if you were happy to have it replaced under warranty by the manufacturer. The problem came when you wished to try and recover critical data that may have been stored on these SSD’s. The use of full hardware encryption on the controller and the device, meant that the data could not be recovered, even when using low level data chip removal.

Fortunately today these controllers are not so popular, and as a result most mainstream manufacturers do not use them. But be aware that they can still be found in some non branded SSD’s.

APFS Data Recovery

When Apple release the latest version of macOS (named Sierra) in Autumn, it will include the new APFS filesystem. Apple haven’t launched a new FS for a long time, and this filesystem won’t work for bootable disks at first. Eventually Apple will make this the default filesystem across the whole product line, from the iPhone, through to the Mac.

APFS Upgrade In Place

I have heard that Apple will release a tool to upgrade an existing HFS+ volume to APFS. If you run the upgrade I strongly advise you to make at least a couple of backups first. I would suggest a Time Machine backup and a bootable full disk copy, with online backup if you have it. While the upgrade is cleverly designed to minimise the risk of disk corruption, there is always the chance that failure could leave you with no option but wipe & start again. This is especially true of older Macs that you may have updated through multiple OS versions and accumulated all sorts of nasties along the way.

APFS Data Recovery

We are already working through the APFS documentation to keep ahead of these failures. We will have some recovery tools ready soon. As with most recoveries, the most important thing is to stop as soon as you hit a problem. Remember my new catchphrase, “Most damage to data happens AFTER the original failure!” Or, “It’s not the failure that killed the data, but the failed repair.” (I know, snappy right.)

If you’ve lost data from an APFS disk, contact us now, or have a look at our Mac Recovery Services for more info.

Seagate SSHD ST4000DX001 Data Recovery

I previously posted about a Seagate SSHD ST500LM000 hybrid hard drive which failed to spin. This hard drive was put into our R&D process due to the type of the failure and further analysis confirmed that the problem was relating to the Solid State part of the drive. At the time I had only seen this type of failure with the Seagate Thin SSHD laptop drives. But since then we have now received Seagate desktop SSHD hard drives with the same type of failure.

Because the SSHD hybrid drives are a cheaper option to SSD drives I am seeing more of them in for data recovery. Also as these are still mechanical hard drives, I am seeing many of the same failures as I do with standard hard drives. For example Electronic Faults, Dropped Drives, Water Damage etc.

Broken USB Stick

USB Broken Connector Data Recovery

I had a call on Friday from a very distraught lady who had dropped her laptop with her USB stick still plugged in. Unfortunately the USB stick took the brunt of the impact and all her work was no longer accessible. She contacted us and I reassured her that although the device was broken, we have a good chance of getting the data back.

With time spent on the Broken USB Stick over the course of the day on Saturday, I was able to recover all of the data. I managed to get the data back to her on Sunday morning, so she could carry on working ready for the week ahead. I was also pleased to find out that the information on the USB stick was part of her charity work for people with special needs.

The customer was local to us in Portsmouth so I had the pleasure in handing the recovered data to her personally.

 

Top 3 Coffees in Portsmouth

Safe Data Recovery

It’s probably worth a quick explanation here. Why is this data recovery blog so interested in coffee? Well personally I love coffee, but I also often recover data from hard drives that have been for a drink (or a swim). So there’s my excuse, now back to the coffee!

Fortunately for caffeine addicts in Portsmouth like me, there are plenty of places to get your fix. I’m the sort of person that finds somewhere I like, and then just keeps going back there forever. Sometimes though, it’s worth having a look at the other options. My current top three places for coffee in Portsmouth are below in no particular order. I’ve chosen three, but I’m always happy to try more places so let me know if you’d like me to give your coffee a try!

Portsmouth Coffee

Coffee#1

Coffee#1 is a small chain of coffee shops spreading like wildfire from Wales, across the South West, all the way down to the South Coast of England. The local branch is in Palmerston Road, Southsea. They do great snacks, cakes & lunches (Sausage & Relish roll anyone?) I usually go for whatever single-origin coffee they have in, and I’m never disappointed. They also have beans & equipment for sale. I recommend the Brazillian beans if you can get them. They are my current favourite for grinding & Aeropressing at home. Visit the Coffee#1 Website

Home Coffee

I’ve only just found out about this place, but I’m so glad I did. I recently went for lunch here & had a big granary doorstep sandwich, an Americano, & an iced ring doughnut. I couldn’t have been happier with all those things.  The cosy shop on Albert Road is just a few steps away from the Kings Theatre, but they are set to open a new store on Cosham High Street, much closer to home for me! They have lots of info about their coffees on the blackboards and are more than happy to have a chat with you about brewing at home. They sell kit & beans too which is handy, although I’ve not tried the beans myself yet.(Update – The beans are great!) Visit the Home Coffee Website

Soprano’s

A bit of a wildcard entry here, and also a hearty recommendation if you like quality fresh Italian food. The Peroni on-tap is always delicious, and their after-dinner coffees are the perfect way to finish a meal. Booking is advised as the cosy restaurant is always bustling with customers whenever I’ve been there. Visit the Soprano’s Wesbite

So there you have my top three coffees in Portsmouth. If you’ve spilled coffee, or any other drink on your hard drive or computer, get in touch. We can help recover the data, and you can tell me if the coffee you spilled was any good!

Another Successful Dropped Hard Drive Recovery

No Chance Data Recovery

Last week I was working on another dropped hard drive recovery sent into us by one of our Data Recovery Partners. I immediately took the hard drive into our clean room and removed the top cover for internal inspection. Although the hard drive had been dropped there were no visible signs of physical media damage. I replaced the damaged internal heads, rebuilt the hard drive and successfully recovered the data for the customer and Partner.

Thankfully the partner had advised the customer to stop trying to access the hard drive as described in our blog. When they received the hard drive from the customer.  They sent it straight to us, without attempting anything themselves.
These actions by the customer and partner were critical in the eventual successful outcome.

Hard Drive Data Recovery

Despite offering world-class data recovery from our workshop here in Portsmouth, we understand that sometimes, the data just doesn’t justify the cost of getting it recovered. If you’re going to go it alone and attempt a DIY recovery, we’ve got some handy tips to avoid making things worse. It might be a good idea to print this page to use as a reference. Also feel free to comment at the end of the post if you’d like any questions answered.

Stop Using Your Hard Drive

If you want to recover data, you can’t do it from the disk you want to recover from. When you boot up a computer it writes data to the hard drive. Even browsing the web or checking e-mails writes little cache files to the disk, potentially overwriting the files you want to recover.

Set Up

You ideally want to work from a different and reliable computer, have plenty of storage space for recovered files, and make sure everything is ready before you attach the faulty disk. You don’t always get a second chance with hard disks, so make sure you’re ready to grab the files if they appear.

Now You See Them

If you suddenly gain access to the files, copy them to another drive as soon as you can. The disk is unlikely to have repaired itself, so this might be the last chance to copy the data before if gives up completely. Take the most important files first. If the copy gets stuck, stop it straight away as the disk could be causing damage.

Watch The Clock

If you decide to try DIY recovery, keep a close eye on the time. If the estimated time keeps increasing it could be a sign of disk trouble. Failure to deal with that could cause the drive to fail completely, and beyond repair (even for us). As a guideline, it should take no longer than a few hours to copy a whole 1TB disk over USB 3.0. If your estimate says much more than that, or keeps going up in time, it could be the disk getting worse. Maybe try copying important files in small batches first. Data Recovery Time Remaining

Priorities

Your priority with a failed drive is either to make a copy of the disk, or copy off the files as soon as possible. Don’t try to scan, repair or fix any errors. A failed repair can completely damage your files beyond recovery. This means don’t ever use spinrite, diskwarrior, techtool, or any other diagnostic tool until after you’ve extracted the data. Some people report success with these tools, but it’s far safer to copy the data first, and run those tools later.

Restore or Reinstall?

Don’t re-install or restore the computer. At best it will overwrite some of the data. At worst it will overwrite all of the data and leave you with a factory-fresh (blank) version of Windows. If you’ve already done this, we can often get data back, but it won’t be as complete as a normal recovery.

Brrrr It’s Cold in Here

Never ever put a hard drive in the freezer. Although this trick is a common part of data recovery folklore, it is likely to do so much more damage than good. We have never used any type of freezing process for data recovery, and neither should you. Leaving your hard disk unplugged for a day is likely to be just as successful, and won’t risk contaminating the delicate disks and heads. Hard disks are not air-sealed so even if you put them in a sealed bag, they already have moist air inside them which can freeze and then cause condensation.

Stop Hitting Yourself

If you saw how delicate the inside of a hard disk was, you’d never consider hitting, tapping or knocking it. Even if you did manage to dislodge some stuck heads, you’ll probably either rip them off, or take a chunk of the disk with it. There are careful ways to remove stuck heads, but they cannot be done at home.

Keep it Together

Never dismantle a hard drive. This is a case when the “no user serviceable parts” label really is true. Not only are disk internals extremely delicate, they have an air filter in the cover to stop particles getting inside the disk. If you remove the cover, all sorts of dust and lint can get in. Dust particles are bigger than the gap between heads & disks, so they can cause the heads to crash into the disks and scrape off the magnetic coating. Once the coating is gone, the data is gone.

Good Luck

If you decide to try DIY data recovery, good luck, and be careful. If you’d rather let us look at the disk instead, get in touch.

Back up as much of the data as possible and replace the disk. See an authorised Apple dealer for more information.

S.M.A.R.T. Status : Failing

If you see the message above, your hard disk or SSD has started to fail and has reported faults to the Mac. If caught early enough, these disks can usually be recovered. You can try to copy important data to another disk but if the copy process gets stuck for a while, it’s safer to stop. If you leave a failing disk in that state it can deteriorate until the disk is ruined.

If the data is really important, and you’d rather not take the risk, you could have a look at our Mac Data Recovery Services. We have been dealing with these sorts of problems for years and have a developed a really safe way to get the data off in good condition.

This drive has a hardware problem that can't be repaired

Whatever you decide to do, don’t ignore this message. The broken disk cannot repair itself, and will only get worse. In many cases, the disk won’t even be readable by the time you see this warning.

It doesn’t matter if the disk is still inside your iMac or MacBook, we can remove it for you, and even replace the drive at the end of the recovery process if you want. Ask about our Mac Setup service if you are interested.
