B&R 10.1 reports the 80GB Seagate system drive on my PC as invalid. The drive works fine as far as I can tell: - shows up as OK in Disk Management - HDtune reports it is OK and doesn't show errors when scanned - CHKDSK completed OK without correcting anything, but B&R still dislikes it - Acronis TI Home 2009 sees it OK, can back it up OK and the backup verifies OK The fdisk.txt report [extract] shows this drive thus: The B&R disk config screen shows this: B&R shows the other drives on the PC as OK and will back them up successfully. B&R works perfectly on another PC, including its system drive. Any suggestions as to how to overcome this would be much appreciated. BTW: The PC runs Windows XP Professional+SP3+updates installed.
