iMac Recall: Don’t Replace That Hard Drive Before Reading

By | June 20th, 2015


Yesterday Apple announced that they were going to be replacing 3TB hard drives that were found in some of the 2012 and 2013 27-inch iMacs. We have a feeling we know what’s going on here, especially if those drives were 3TB Seagates, and it sounds like they were!

Backup Before You Replace Your Apple Hard Drive

To check whether you have an affected iMac from 2012 or 2013, you can check your Mac’s serial number on this website: iMac (27-inch) 3TB Hard Drive Replacement Program. Before taking any computer in for service, make sure you have a good and up-to-date backup of all that computer’s data, whether it’s a Mac or a PC. On their replacement program page Apple reminds users:

Before you go in for service, Apple strongly recommends backing up your data. Learn more about backup options.

Of course the majority of their backup options lean around Time Machine and iCloud, but if you want your data to be safely and securely stored outside of the Apple ecosystem as well, we recommend obviously Backblaze!

    what is the process for transferring backblaze from my machine, before taking in to apple to change the HD. ie: do I have to do something BEFORE taking it in, so when it’s installed on my reformatted new HD it just counts as 1 user account?

    I read this FAQ, ( but that sounded like I needed access to both ‘old’ and ‘new’ computer together… but in this case, where my HD is being replaced, I wont be able to do that

    Why copy to the cloud when you have time machine? Yes backblaze is something i use but i also use time machine. Backblaze is for if time machine fails (for me at least).

    Hopefully it is not too late to start copying GBs of data on a faulty HDD to the cloud.
    I would suspect most Mac users keep back-ups?
