Provide as much detail of the issue here:

I got 4 new Toshiba drives - 64gb USB 3.0

Previously using 4 x 32gb usb 2 drives...

I formatted the new drives to fat using disk util and a few other apps through windows to try various things.

I can export to the old drives with no hassle at all.

2 of my new drives after exporting the 2 folders im trying to get on there i keep getting - DEVICE LIBRARY CORRUPT

There are no errors during the copy process or when i plug it in.

If i copy and eject safely, plug into a cdj it doesnt find the playlists "as if its corrupted"

Sometimes it also crashes rekordbox when i plug in.

All my mp3s are on my SSD, so ive done numerous re exports.

When deleting/ renaming the .edb files which should i do?

Waht should i use to analyze for corrupt audio?

I dont think its audio as it copies with no hassle and works on the usb 2 32gb
