Recovery system says backup is corrupted
I took an "Entire PC" backup of a Window 7 PC. When I then brought up the Linux recovery system from USB flash "drive" and validated the backup. It reported that the backup was corrupted but I could still try recovering files. It gave no indication of what was wrong. I then rebooted Windows and ran a validate under TI 2015. I got no error message so I assume it passed validation.
This backup is needed for a full system restore - recovered to the original disks. The backup is either usable by the Acronis Linus recovery system or it is useless. I assume it restore from a file it thinks is corrupted.
I'm currently doing a TI 2015 validation of another PC's "Entire PC" backup. I will then try validation of that backup under the Acronis Linux recovery system.
BTW, I created the the recovery system under using TI 2015 - there isn't (or shouldn't be a) an incompatibility issue.
Update:
I've tried a few more things.
1. On the problematic PC, multiple backups on my external drive fail validation by the Linux recovery system. None that I tried succeeded. However, they all passed validation done under TI 2015.
2. On the problematic PC, a disk backup done to an internal hard drive passes validation under the Linux recovery system.
3. On a different PC, an "Entire PC" backup to an external drive passes validation done by the Linux recovery system.
Is there any way to fix this other than use a different external drive? This is an old Seagate USB 2.0 desktop drive. (1 TB, I think.)
