  • macOS Big Sur “Bricking” Some Old Macs

    Reports came in over the weekend about a nasty problem caused by installing the new release of macOS Big Sur. If you have a 2013 / 2014 MacBook Pro, it’s best to wait for Apple to release a fix before you attempt to install the update.

    If you’ve already installed the update

    Although you may not be able to boot the laptop, and all startup keys will fail to get it going, we will still be able to recover your data from MacBooks effected by this problem.

    You need to proceed very carefully, as some online advice suggests erasing the Mac which means you’ll lose all your data!

  • Free & Cheap Backup for iPhone, iPad, Android, PC & Macs

    If you’ve survived without backups and not lost data, you’ve been lucky so far. But why push your luck? There are a bunch of free & cheap ways to backup that could save you from the pain of losing data. Even better, you could help out your family, and give a gift that almost nobody will thank you for. At least until they drop their phone down the toilet. Then you’ll be hailed a total hero!

    What is a Backup?

    First, I have to get this out of the way. A backup is an extra copy of the files. If you don’t have two or more copies of something in different places, it’s not a backup. A common mistake is buying an external “backup” drive, and then filling it up with data that you don’t have anywhere else. All that does is move the problem from one disk to another. If the “backup” drive fails you’ll still need to get it recovered professionally (👋). If you had another disk with the same files on, you’d be fine. It might sound wasteful to keep multiple copies of your files, but it is the only safe way. Even the most reliable disks have a 1% failure rate. If you made a backup copy of a paper document, you wouldn’t shred the original, so just think like that.

    What is a Cloud? ☁️

    A cloud is just a server somewhere. Modern cloud services are just huge networks of servers that can store your data.

    iPhones & iPads

    iCloud

    If you’re an iPhone or iPad user, you can’t beat iCloud for convenience. With an iCloud backup, you can load a replacement iPhone or iPad with your data, and carry on where you left off. It might seem unfair that Apple will sell you a phone for £1,099 and then want an extra £0.79 per month for iCloud, but once you get past that, it really is worth every penny. For under £10 per year, you’ll be mad to not sign up.

    Family Sharing

    If you have multiple iPhones & iPads in your household, you can also share iCloud storage using Family Sharing. That way, you can buy one of the larger storage plans and backup all the iDevices in your house. All the data is still kept privately for each person in iCloud, but the total storage is shared. This will also give you some other useful features like shared family calendars, notes & reminders.

    Google Photos

    Google photos works across pretty much any device. It doesn’t matter if you run it from your iPhone, Android Tablet, a PC, whatever. The free version only has a fairly small allowance (currently 15GB), but you can then pay extra for more storage as you need it. (£24.99 per year for 200GB in 2023)

    Android Phones & Tablets

    Google One. That’s the Google equivalent of iCloud and has tools to backup devices, and photos. (See above.)

    Mac & PC

    Regardless of what PC or Mac you have, you can’t beat an external hard drive for value. As long as your internal disk is big enough to fit all your files, you can then use an external drive to keep an extra copy of everything. If your internal disk is too small, the best option is to upgrade it, and then also keep an external backup drive. If you don’t (or can’t) upgrade the internal disk, you’ll need to juggle data and backups around external disks. This increases your risk of missing something.

    Computers can also use cloud storage, so if you already use one on your phone, it’s worth seeing what you can share with your PC or Mac.

    iCloud on your Mac will let you sync photos and documents but doesn’t allow you to backup and restore to the cloud the way it does with iPhones. If you use iCloud on a Mac, I’d still recommend an external drive.

    Attach an external drive to a Mac, and it will offer to use it as a backup with Time Machine. ⚠️ Be aware that it will erase the disk first! Time Machine will take a copy of your whole Mac, and keep it up to date. Even if you only plug the disk in once a month, Time Machine will catch up with any new files and copy them over automatically. If your Mac dies, you can use the backup drive to load the data to a repaired or replaced Mac.

    Windows 10/11 has a backup feature named “File History.” Much like Time Machine, you can select an external disk for backups, and then file history will keep track of file changes automatically. Unlike the Mac, File History doesn’t backup software and settings, so you’d need to get things setup another way first before you load the files back.

    Conclusion

    Do yourself a favour and get your files backed up. Remember, you don’t need to backup everything, just the things you don’t want to lose 😜!

  • (Possible?) World’s First Apple SSD Recovery

    (Possible?) World’s First Apple SSD Recovery

    Apple’s PCIe SSDs have always proven challenging for data recovery. We have a good success rate with them, however many of our tools don’t even support working at PCI level. This particular SSD provided a new challenge though.

    The Device

    Manufacturer: Samsung
    Model:
    MZ-JPV5120/0A4
    Controller:
    S4LN058A01-8030
    Capacity:
    512GB
    Interface:
    PCIe
    Date:
    2015.11

    MacBook Pro SSD

    The Problem

    The SSD we received was initially showing up correctly in the system. Upon access, the disk would read a few bytes and then stop reading. The SSD would remain visible to the system but not respond to any further commands. The only way to bring it back was to cycle power. Yep, the IT classic — Turn it off and on again! The problem is, PCI cards don’t come with on-off switches so the solution needed to work within software.

    Brainstorming

    First I thought a copy task with a scheduled reboot may get the device back online, however I quickly found out PCI slots stay powered on during a reboot 🤦‍♀️ This means once the device gets stuck, a reboot won’t bring it back on.

    My second idea was to schedule shutdowns but the time taken to boot and then restart the copy process seemed like a nightmare.

    The Solution

    In the end I found a series of commands which could keep a fairly steady copy process going. The main idea was:

    • Start a copy task
    • Pause on error
    • Toggle the PCI connection using low-level commands
    • Resume the copy task
    • Rinse & repeat

    Although not the most elegant solution, this process cycled through 647 times, taking an average of 760MB per cycle. In less than 24 hours the whole 512GB device was cloned to another disk ready for recovery.

    After this script finished I did find a slightly cleaner way to reset the PCI slot which will result in much faster recoveries in the future.

    I was unable to find any mention of this type of recovery online, so if anyone else knows about it, they’re keeping it to themselves. If you know anyone with a failed Mac SSD, get in touch. This is just one of the many solutions we have for recovering them.

  • Fusion Drive Data Recovery

    Fusion Drive Data Recovery

    Urgent Warning: Fusion Drive always consists of two separate disks. If you want your data back you must get both parts. We’ve heard a number of reports that users with failed Fusion Drives are only given the Hard Disk back when receiving Apple repairs. On its own, the hard drive is not enough to recover all data in original condition. This is especially true if FileVault encryption is used.

    HDD + SSD = Fusion Drive
    HDD + SSD = Fusion Drive.

    What is Fusion Drive?

    Fusion Drive is Apple’s version of a hybrid solid state & mechanical disk. It combines a small fast SSD with a large slow hard drive to achieve a balance between cost & performance. Frequently used files are moved to the SSD, and old stale data is sent to the slow hard drive. This is all taken care of automatically behind the scenes. Unless you dig into the terminal, you wouldn’t even know you had two separate disks inside the Mac. Fusion Drive is  part of Apple’s Core Storage system. It is somewhat similar to Linux LVM as a volume management system.

    What Fusion Drive is not

    Fusion Drive does not use the SSD as a cache for files but actually moves data from one disk to the other. This is important, as both disks are required for full recovery.

    Why does Fusion Drive exist?

    At launch, and even now, the cost for large capacity SSDs is way higher than the cost of an equivalent hard drive. The problem is that SSDs offer huge benefits to the user experience. When you use an SSD, you hardly ever have to wait for things to load. The computer boots up within seconds.

    Hybrid drives aim to bridge the gap between solid state and mechanical disks. An iMac with a 3TB Fusion Drive comes with some of the benefits of SSDs, but much less cost. As the cost of SSDs fall, the need for Fusion Drive will eventually disappear. Apple has shown with their current lineup that they’d much rather go all-SSD where possible. Current iMac Pro & MacBook Pro both use 100% SSD internal storage.

    Anecdote Corner

    We’ve had two recent cases where a user has brought a “Fusion Drive” to us for recovery, but actually only had the hard drive part. Apple had given the damaged hard drive back after replacement, but reused the SSD when creating a new Fusion Drive. This user only had a few GB of data so the Hard Drive hadn’t even been used yet. All the data was stored on the SSD which was now overwritten.

    The majority of Fusion Drives we’ve seen have a Seagate ST3000DM001 3TB hard drive combined with a 128GB blade SSD.

  • OS X Base System Data Lost

    We’ve seen a few cases recently where a user has unexpected lost all data, and been left with a disk named OS X Base System. Inside the disk is a file named Install macOS Sierra or Install macOS High Sierra, and a few other system files.

    The OS X Base System is usually part of a macOS installer or update, so it’s unclear how disks ended up getting replaced with this.

    If this has happened to you, we’d love to hear more about how.

    We can usually recover these disks, but it’s really important that you stop using the disk as soon as possible. If you install anything to the disk you could risk losing all the data permanently.

    We’ve still got more of these to investigate so we’ll update the post when we’ve learned more.

    Update: Could be related to Internet Recovery?

  • Add Another Time Machine Disk

    If you need to add or change your Time Machine™️ backup drive, the process is pretty simple. Plug in a new disk and make sure there is nothing on it that you need. In most cases Time Machine will ERASE the disk before using it! You have been warned.

    Now might be a good time to find the disk on your desktop and rename it to something obvious like “backups” for example.

    Next, open Time Machine Preferences from the Time Machine menu. If you don’t have the Time Machine icon near the clock, you can also find the settings within “System Preferences”.

    Open Time Machine Preferences
    Open Time Machine Preferences

    Click Add Or Remove Backup Disk
    Click Add Or Remove Backup Disk

    Select the New Disk
    Select the New Disk

    Click the “Use Disk” button, and Time Machine will start making a new full backup to this new disk. This may take a few hours.

  • Stuck MacBook Trackpad Bulging Battery

    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.

    Explosion?

    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)

    Check

    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.)

    MacBook Service Battery

    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.

    What Next

    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 ?.

  • The Worst Head Crash Ever?

    The Worst Head Crash Ever?

    I’ve seen some pretty serious head crashes in my time. The worst part of my job is knowing I’ll have to tell someone their data is gone forever. Sometimes media damage can be subtle enough that it’s impossible difficult to even detect by eye. Other times the damage is obvious. Today was one of the clearest I’ve ever seen. What’s worse is that we got two of these identical disks from the same Mac Pro, with identical damage. You have to see it to believe it…

    Worst Head Crash Ever?
    Worst Head Crash Ever?

    It’s difficult to know how long these damaged disks were left spinning, but it looks like months! If you look closely, you can see that the centre of the disk is worn right through. That black dust everywhere was once the shiny disk surface that stored the data. Nobody in the world can recover data from disk dust.
    The easiest way to avoid such serious damage is to power off your hard drive as soon as you hear clicking. If we got these disks sooner it’s possible we could have recovered them.
  • 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.
