OK so I reformatted my hard drive and used Express HD as a disaster recovery tool. It worked perfectly. My first subsequent backup worked perfectly.
Since then I keep getting yellow dots telling me there are problems during the backup.
The latest problems are these:
12/6/2009 2:32:04 PM: Copying Local Disk (C:)
File "C:\NVIDIA\DisplayDriver\195.62\WinXP\English\PhysX_9.09.0814_SystemSoftware.exe": can't read, error -1127 (data error detected in file using cyclic redundancy check)
12/6/2009 2:52:47 PM: Snapshot stored, 139.2 MB
12/6/2009 2:53:01 PM: Comparing Local Disk (C:)
An error occurred during the verification step. The MD5 digest for the file "C:\Program Files\Common Files\Adobe\Adobe PCD\cache\cache.db" did not match, error -1129 (MD5 digest mismatch)
12/6/2009 2:56:28 PM: Execution completed successfully
Completed: 506 files, 3.0 GB
Performance: 551.6 MB/minute (403.2 copy, 873.0 compare)
Duration: 00:24:24 (00:13:31 idle/loading/preparing)
Can anyone diagnose why I get errors with certain files?
