    How long should First Aid take?

    I have an external HDD (4TB G-Drive) 2 or 3 years old. I use it mainly for TM backups, and also for archiving some stuff. DriveDx rates it as "Average 52.1%". It seems to function just fine. But I've become aware recently that there's a user ID mismatch between my current system (and more recent...

    I accidentally started decrypting my empty 5tb external hard drive because the encrypted drive won't show password hint

    I bought a new 5tb Seagate external drive and encrypted it with Disk Utility with a "passowrd hint" on my 2019 Macbook Pro (Catalina). The drive has never been used and is empty. However, the password hint did not show when I plugged it back in, so I thought maybe I should redo the encrytion. I...

    Resolved Installed Monterey now Disk Utility looks different, I think.

    Installed macOS Monterey and when I went to disk utility I saw this. Is it normal for the M1 iMac 24" ? My older iMac only showed Macintosh HD and Macintosh Data Thanks for any insight.

    Hi, Today I noticed my external Samsung HDD is very slow suddenly. It’s also impossible to eject it from my Mac (I have to turn off my Mac every time I want to eject it). So I have run First Aid on it in Disk Utility. Here’s the result: What does it mean? Is this disk unfixable? Is recycling it...

    WD My Book Duo: Use device raid/encryption or Disk Utility?

    Hey there, just got a WD My Book Duo. I'd like to set it up as a RAID 1 and use encryption. Question is, do I use WD's utility to set up RAID and encryption? Or just use Disk Utility? The drive has Hardware Encryption, which I guess won't be used if I enable encryption via Disk Utility? Same...
