USB Key error: can't unmount... PLEASE Help!
Hi!
I hope I am posting this in the proper category.
I have been pulling my hair trying to re-format my USB Key and it's not working... I keep getting the same error: Couldn't Unmount Disk.
This is what I have been doing:
I open Disk Utility,
Select the USB on the left,
Select the Erase Tab on top,
Select the Format,
Click Erase
And I get the message below...
Just so you know, I have backed up everything on that key already so that's why I was trying to re-format. I also am not able to save anything on the USB key.
Also, I clicked "Verify Disk" and it said it appeared to be OK but when I tried to "Repair Disk", I got the error you see above in red.
PLEASE someone help me... I've researched online and tried everything but nothing is working... Hope I stated everything clearly and someone out there is nice enough to help! Thanks!
