I have a particularly nerdy Apple rabbit hole to share with you today involving the labels on Apple hard drives. At some point around 2007-2008 Apple started re-labelling the hard drives used in their computers. I’m pretty sure the hard drives in black & white MacBooks were standard white labels with an Apple part number (655-XXXX) printed on them. Now disks feature a black label with white text. Not particularly exciting, but maybe somebody (Jony?) wanted the disks to match the fancy black circuit boards now used in all Apple hardware. That’s the sort of attention to detail we’ve come to love from Apple devices. Whatever the reason, this has resulted in a batch of Toshiba drives in circulation with incorrect information printed on them. I assume these are the result of a simple ⌘+C, ⌘+V error. My speculation is that after printing the labels for the 320GB disk nobody remembered to change the text for the 160GB version.
For reference MK3253GSX is 320GB and MK1653GSX is 160GB. In Apple’s world, both disks use MK3253GSX on the label, even though the correct number is shown when you check Disk Utility or About This Mac > System Information.
This wonky number business all came to a head ? when we were looking for replacement parts for one of these disks. We needed the double headed 160GB drive, not the four headed 320GB.
When I was trying to research this, I was quite suprised to find an old blog post of ours that shows the same problem with Hitachi drives manufactured around the same time. I’ve not found any other mention of this labelling fault, so thought I’d post it up here for future Mac Archaeologists to find.
We’ve had our fairshare of unusual and difficult recoveries over the years, but I have to share a photo of this bent iPhone we recently recovered. It’s an iPhone 5s that has seen better days. I’d love to know how anyone could bend a phone that far without also smashing the screen! It’s impressive.
As always, my first concern was extracting the damaged Lithium battery. I removed that straight away and disposed of it before starting the recovery.
With a bit of TLC and a new battery and screen, the phone was just about working. It stayed working long enough to get an iTunes backup, and extract all the data.
If you have a MacBook or MacBook Pro that’s a few years old, you might have a problem hiding right below your fingertips. If your trackpad has become difficult to press, or stopped clicking all together, you could have a dangerous faulty battery. In MacBook & MacBook Pro laptops, the battery is directly below the trackpad. When the battery fails it can expand, pressing into the bottom of the trackpad.
I’m not sure quite how risky these batteries get, but they almost double in size. Standard battery advice says don’t pierce or burn but when these battery start expanding they could easily get punctured. I saw one so bad last week that the bottom case and trackpad were being pushed apart. (see photo below)
If you click the battery ? icon near the clock at the top-right of your Mac screen you can check the status. (If you don’t see the status, press the option (alt) key before clicking the battery icon.)
From Apple’s help document
You may see any of the following conditions:
Normal: The battery is functioning normally.
Replace Soon: The battery is functioning normally but holds less charge than it did when it was new.
Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was new. You can continue to use the battery until you replace it without harming your computer.
Service Battery: The battery isn’t functioning normally, and you may or may not notice a change in its behavior or the amount of charge it holds. Take your computer in for service. You can continue to use your battery before it’s checked without harming your computer.
If your status shows Replace Now or Service Battery, I would look to get the battery replaced as soon as possible. At the very least, a bulging battery could cause cosmetic damage to your Mac. At worst it could potentially leak or catch fire ?.
If you have a computer, tablet, or mobile you most likely have some of your data stored in the cloud. It may just be syncing your contacts or calendar, or even backing up your photos from your iPhone or Android phone. Whatever the reason it is now a cheap way of keeping your data safe. Or is it?
Never take for granted that your data is getting backed up correctly. Check it yourself.
I had a situation just recently where my wife’s iPhone had just gone through a 60℃ wash.
“That’s okay,” I said, “We have all your data on iCloud…”
A few days later we replaced the phone (thanks insurance) and restored the data back from iCloud. That’s when we discovered iCloud hadn’t been copying Contacts and some other data. Fortunately I had also kept another backup using iTunes on my Mac so was able to restore from there.
Now would be a great time to check your iCloud settings and make sure there’s a green tick next to everything you don’t want to lose!
Another thing to look out for, especially if you have a lot of data, is your upload speed. Unless you have fast broadband, uploading large amounts of data can take time. You’re unprotected until all of the data has reached the cloud. In some cases it can take hours, even days, depending on how much data you have and the speed of your network.
Once you have uploaded all your data, your device will only need to copy new changes so won’t take so long. As a Plan-B, don’t forget to backup to a computer once in a while. You can thank me later.
Don’t leave it until it is too late. You never know when your phone will take a spin in the washing machine.
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.)

We recently received a Macbook Pro for data recovery. When we removed the broken hard drive and installed a new one for the customer, we noticed that the trackpad was not working correctly and would not click when pressed. We dismantled the Mac again and removed the battery which was underneath the trackpad. When the battery was removed we found that the underside of battery had blown and was pushing against the trackpad. We installed a new battery, recovered the customers data and now the mac is working fine.
This drive has a hardware problem that can’t be repaired.
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.
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.
This year we have seen a fair number of these particular model hard drives with internal media damage caused by a head crash. These are 3.5″ hard drives from external cases such as Seagate Freeagent Go-Flex and Seagate Expansion Desktop. They are also used as internal hard drives in PCs running Windows 7 & 8 also used in Apple iMac’s running OSX.
It has been difficult to confirm whether the media damage seen has been caused by an impact such as a dropped drive or from general electronic failure. What we do know is that as soon as you hear one of these hard drives start to click, then if you have not already got a backup in place, backup your data immediately.
On an Apple Mac running OSX the first sign of a problem is usually a spinning beach ball resulting in slow access. On a PC running Windows 7 & 8, the signs of a hard drive problem are once again slow access and lack of movement from the mouse icon.
If you have a problem with a Seagate hard drive, have a look at our Seagate Data Recovery Services. If we catch it early enough we should be able to recover the data!
You may be surprised by some of the old computer hardware that’s still used by some companies today. Especially where they are used as the control interface for manufacturing purposes. We recently received a Quantum 40MB SCSI II hard drive from an old Macintosh IICX that was controlling a piece of 7 Ton Fabricating equipment. The software communicated to the CNC equipment through an internal Nubus card with SCSI interface. For the customer it was not just a case of getting the user data off the drive, but to get an exact image so they had a bootable drive with all the relevant software and drivers to run the CNC machine. With our experience in old computer hardware especially old Macs and DOS based PC’s we were able to recover the data from the hard drive and make a bootable replacement drive to get the customer back up and running. For the customer there was no other option but to get his old Macintosh IICX back up and running as new CNC equipment was too expensive to replace.
Old Macintosh & DOS CNC Machines
This is not the first time we have been involved in this sort of request and process. Back in 2008 we had a similar situation with a customer who had a CNC milling machine that was run by an old DOS PC with a Fujitsu M2682TAM hard drive. Again we managed to get a bootable image back to the customer.
So if there is anyone out there running “obsolete” PC’s or Macs, then you know were to come to get the best outcome.
