The drive backup hangs at about 90%. The drive lights keep blinking, but never completes (half hour plus for a drive of about 1GB). Also the cancel button is grayed-out so users are forced the shut-down to safely remove USB drive.
Using PR2 on Mint Linux 10 (Ubuntu Maverick)
selecting entire drive w/ 7z, not maxed.
Seems OK on Win 7 though.
