Background: Backup and Restore was working fine here in Windows 7 Home Premium until I encountered hard disk cabling problems and the backup would just die, or would freeze the machine. Event 129, 'Reset to device, \Device\RaidPort1, was issued' was realized in the event viewer. In any event, at some point I removed power from the machine without shutting down windows and that messed something up, I believe in the registry somewhere.
The cabling problems are resolved but now Backup and Restore "lost" it's configuration and trying to reconfigure (set it up again) causes the 80070057 parameter error when clicking on "save settings and start backup" (after changing source and destination files/drives and resetting my modified US Regional settings).
The following were tried to no avail:
- chkdsk /r on all partitions
- sfc /scannow
- clearing the appropriate registry entries in HKLM (as documented elsewhere in this forum)
- running in a clean boot state
- running in safe mode
6. reading every appropriate forum post in here (some with questions not answered)
The only thing I've found to fix it:
Clean Installation of Windows
I don't wanna do that if I can help it.
Any Help?
I learned today that I also had a problem with the Task Scheduler. The thread (the URL below) shows the answer to fixing that problem, which is: Backup and Delete the contents of the C:\windows\system32\tasks folder. It also fixed my problem, because the configuration file (and other files) for Backup and Restore is stored here: C:\Windows\System32\Tasks\Microsoft\Windows\WindowsBackup
Oh happy day :)
