At this point, I figured the disk was now blank. It revealed that there was no file system. I tried some other Terminal commands, such as "repairVolume". But that's a good command to keep for future reference (When I get a newer computer. Use the Terminal Command to get a list of drives using the command diskutil apfs list and see if it appears. Thanks Patrick! Doing this certainly made my project easier. Unmount and disconnect the other working drive while you do your diagnosi with the other goofy one. It's fine directly connected, but won't be recognized when in a hub. One of my thumb drives acts like you described. Actually, I tried it both ways, just in case the (powered) hub would have some positive effect. Is the drive being connected to the Mac, or is it being connected to a hub? Mounting from Terminal didn't work unfortunately. The Mount command confirmed the drive was not mounted. Thanks Ashwin for your explanation of the Diskutil command. No luck, Jake- But a good thing to remember for next time. You might try powering down, connecting it, then booting again with it attached. The drive "fixed itself", as explained later. Thank You Everyone for teaching me & helping me with this drive problem. The result told me the drive is the problem, not the enclosure.įirst I believed the drive was bad, but Terminal shows that it is mounted, so it can be seen by Terminal.ĭo you all know any tricks to get the drive to mount, or is it destined for the recycle bin?
After that I tried the drive in another enclosure and a known good drive in the USB enclosure. The bad guy drive has an arrow pointing to it.) The other drives are the computer's hard drive and a partitioned external that does work. Terminal app's List command shows it is, indeed, mounted. I tried Terminal App to mount it the long way. (Without the offending USB drive attached) I have to re-start the computer to get Disk Utility to act properly. Actually, even closing the application and re-opening it, I get the "Loading Disks" message. If I open Disk Utility, the page says "Loading Disks" for as long as I leave it.Īfter removing the drive, Disk Utility won't show the remaining (mounted) disks. When I plug it in, the light on the enclosure flashes for as long as I leave it, but it never shows up in Finder or on the Desktop. I have a hard drive in a USB enclosure that won't mount anymore. I don't know if this is the correct section for this question, so please forgive me if I missed.
