The Replica device (2TB) has been backing up the system drive (C for awhile.
Recently the C: drive experienced a failure that caused data corruption.
Attempting a system restore (from the recovery CD, ISO version 1.01) always results in an error dialog
indicating that it appears that the USB replica device is not plugged in.
This same behavior is exhibit on two different computer systems using the replica drive and the recovery CD, ruling out BIOS issues.
This same behavior is seen with two different USB cables ruling out wiring issues.
In the failure cases mentioned above, the Replica USB dock's lights work OK, and the drive can be heard spinning up.
The drive's contents and file system continuity have been validated on a windows XP machine by plugging the Replica drive in via USB, and by exploring the contents of the drive.
Additional supporting information:
- After formatting a new disk drive and installing WindowsXP and NTBACKUP, NTBACKUP was used from WindowsXP to look at the full and differential backup (BKF) files on the replica drive connected via USB. The differential backup file can be successfully explored using NTBACKUP. However, the Full backup BKF file, when opened with NTBACKUP indicates that the file cannot be read correctly. This would appear to indicate the replica backup file is corrupted.
- I have noted that the replica icon is not showing up in the taskbar on the newly installed WindowsXP system, even after plugging the replica drive in. This appears to indicate that at least portions of the replica software itself are no longer on the Replica drive.
Please let me know if you can think of anything else that can be done to accomplish a rebuild of the system drive from the Replica backup.
