New Thumb drive dies while formatting?

I just brought home a thumb drive. PNY 32GB 3.0. I tried to reformat it for mac via a 2011 iMac using High Sierra. I used os journaled extended and the disk just died. I threw disk warrior at it and I am told that the directory is badly damaged and can't be recovered.

Has anyone ever had this problem. I also got a sandisk 3.1 128 GB thumb drive. I want to format it as well, but I am afraid something will go wrong.

Is there anything I did wrong? I have have formatted many disks via disk utility with no problems.

Cheers!

Not sure if it’s part of the problem or not, but your 2011 iMac only has USB 2.0 ports.

If jack-19’s formatting advice doesn’t get it working, then return it and try a different USB 2.0 FlashDrive or external Hard Drive.

Hi nelsonmay,

This is 100% the reason why I don't like/use flash drives. I always use external hard drives, or external SSDs.

But, please try this:

Go to Disk Utility.
Select "View" > "Show All Devices".
Select the top, non-indented, flash drive.
Click Erase
Pick a name, use Mac OS Extended (Journaled), and GUID Partition Map.
Click Erase and test again.

Cheers,

Jack

Wouldn't be the first failed flash drive, and won't be the last. Try the flash drive on a different system, as a test. If the problems persist across systems, see about returning the drive for an exchange.

I have never used the GUID Partition map option. It worked on the other drives. I just had a bad one. I buy them cheap so I can send things to my parents and friends. I also send my files to my accountant who can never seem to be able to download them from cloud apps.
