It’s already formatted in exFAT. When it halts with that error message,and I view the drive in My Computer, all it shows is ‘exFAT’ – and it shows no unused space. It doesn’t want to ‘eject’ like a regular USB accessory, so I just shut the machine down, remove the USB drive, and restart. From there, whe I start the SecureAccess2, it’s seemingly back to normal – but NONE of the files I was trying to move are present. This software is about as unreliable as it gets, and it uses up gobs of my time. There just has to be a better solution.
