disk utility

I erased a Fusion Drive in an old iMac from Recover mode (lost passwords) and was then installing from a TimeMachine backup, starting from Recovery Mode. After copying over about 130Gb, for some reason the iMac shutdown. I tried restarting, but it shuts down midway during boot. Then I went...

I am trying to set up my new internal SSD (WD_Black SN750 2TB) with a Sintech adapter on my late 2013 Mac Pro after my factory 256gb ssd failed a bit ago and am having issues where the new SSD seemingly is not being recognized. To begin I prepared a USB boot drive (tried both Big Sur & Mojave)...

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...

Running Sierra 10.12.6, MacBook Pro Retina 13-inch. Ran Disk Utilities after a freeze, said I needed to repair start-up disk. Ran DU several more times, no love. Restarted in Recovery mode, ran DU several times, said everything was fine, but upon restart to normal, DU still says it needs...

hi friends - I have a drive mystery, trying to solve for a professional friend. It appears simple on the surface but there are complications. It is a Iomega typical 500GB external drive. It has a valid HFS partition of ~490GB, 141GB of that 'used', which checks out Healthy in Disk Utility...

I bought a brand new Samsung T7 SSD, and I used macOS's Disk Utility to format (erase) it in APFS(Encrypted), scheme: GUID Partition Map. Before erasing (brand new), "Used" space was 108,5 MB. After first erasing as APFS(Encrypted, scheme: GUID Partition Map), "Used" space was just 20 kb. Then I...

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...

I am trying to reinstall OS X using Disk Utility, but I keep running into problems. I always get errors like ‘unable to write to the last block of the device’ and ‘unable to delete the CoreStorage Logical volume Group’ whenever I try to erase/partition the HD. Anyone have any solutions?

Here's everything I've tried. 1) Since my Samsung T5 SSD is in Ex-fat format and seems to work properly. I backed up 3TB data and then formatted it to ex-Fat and moved the data back. It still doesn't seem to work. 2) I've tried using WD discovery to mount. It just doesn't work. Not even an...

On my new M1 Air (1TB), Disk Utility is showing that there's a Data volume (803.22 GB), com.apple.os.update-{long string} (14.95 GB), and Free (174.75 GB). A couple questions: What is that "Free" volume(?). Storage Management is saying I have 702.51 GB free out of 994.66. When you add up the...

Hi there folks, I've clean installed Big Sur for the second time today, and noticed under the Macintosh HD - Data under Disk Utility says 100GB used... is this normal? Can anyone confirm this?

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...

I have two LaCie Rugged discs. One of 500GB and one of 2TB. In Big Sur I only get the option of formatting them in the APFS format. exFat is no longer available. Can you confirm this? Or do you still have the option to format in exFAT. What to do when I need the disc to be available in Windows...

Okay, so first off, I messed up hard. I downloaded Windows 10 to my Mac via Bootcamp. By accident and me being dumb, I deleted Windows off of my mac through the windows side. Now I did backup my mac beforehand, so I was able to reinstall macOS Catalina, but I had to reinstall through Bootcamp...

Gang this regards a lovely 2014 MBA with the default Apple 128GB SSD. I have been searching for simply how to get the option, when erasing a disk, to format it to APFS. When I start with Command + R, and choose Disk Utility, I have a different Menu than what I see in the numerous threads on my...
