I have an Ubuntu Linux machine that I'm trying to back up with the TrueImage build 3567 boot disc. When partitions are checked TI displays error "Failed to read from the sector 76,180,230 of the hard disk 1" (and many subsequent sectors). (If I ignore the error) During the backup "E000101F4 Failed to read data from the sector 72,254,357" (and many subsequent sectors). Ubuntu seems to run great, no errors, even when disks are checked (every 30 boots). Partitions are ext3. Any idea how I can get the backup to work?
