I have a SanDisk USB drive, and I tried reformatting it the other day. It told me it couldn’t write to the partition table.
Now if I go into Disk Utility and try “Erase”, I get
Unmounting disk
Erasing
Couldn’t open device
I’ve rebooted a few times. I can’t mount the disk either.
Does anybody have any ideas about how to recover from this? Or is the drive just toast?
It shouldn’t be an age/wear thing, as the drive is only a few months old - and it’s only been written to maybe a few times total. Just a few OS installs.
Thoughts?
