Sounds to me like a problem with your USB drive rather than with Easy Transfer.
The mig10 file is corrupted. Copy all the other mig files off the drive and then run something like CHKDSK to try to repair the USB disk. With any luck, the corruption is in the file table rather than in the file itself.
Good to see you got it sortedNothing worse than telling a customer you ballsed up and lost their stuff (I did, once
)
Lession for anyone reading this in the future is - don't rely on Windows to back up your data!
