backup using shadow copy causes blue screen stop -- everything elseOK

[Guest bobfnospam@duxsysnospam.com]

On a Windows XP Pro with SP2 on a 3.2 GHz Dell Dimension 9100 with

hyperthreading and 3 GB RAM:

 

I just replaced the original system disk, which was having permanent

disk errors, with a larger disk using Seagate's cloning utility. The

system works perfectly except for one thing: I cannot use the backup

utility (ntbackup) if volume shadow copy is not disabled (and it cannot

be disabled for system state backups).

 

What happens if volume shadow copy is not disabled is that I get a blue

screen error BAD_POOL_HEADER, Stop code x19, parameter 1 is 20. If

volume shadow copy is disabled, the backup works properly.

 

What seems creepy about this error is that previously, with the old

system disk that the disk check utility said had bad blocks, the only

times in which disk errors actually appeared in "real use" is when I was

doing a backup with volume shadow copy!

 

Since the problem described above has appeared, I've put the hardware

through Dell's full troubleshooting suite -- everything passed. It's

been through disk error checking (including bad block scan) several times.

 

I've also enabled driver verification, checked for newer drivers for

disks, and removed some possibly questionable software (including Norton

corporate anti virus). Nothing has changed this error.

 

Since doing a volume shadow copy seems to be a key ingredient of this

problem, is there any program other than ntbackup that exercises it?

 

Is there any way to independently verify the operation of volume shadow

copy?
