Question : BSOD with "BAD_POOL_HEADER" when running backup

Whenver I try to run Msft Backup or Norton Save and Restore I get a BSOD with BAD_POOL_HEADER. It also says:

 xxxSTOP: 0x00000019 (0x00000020, 0xE6C5E800, 0xE6c5E820, 0x0C040601)

This actually started about 3 months ago with a copy of Norton Ghost. I assumed that that somehow I had introduced an incompatibility between Ghost and XP, so I uninstalled Ghost, and replaced it with Save and Restore. Same problem and result. Then I tried the standard Windows XP backup. Same problem and result. Note: This only occurs when i try to backup an entire disk drive to a new drive, e.g., create a mirror. The backups work perfectly fine if I backup individual folders one at a time.

Answer : BSOD with "BAD_POOL_HEADER" when running backup

Try the following (from pad1963's link - solution was not posted until 1/16 though - so re-read if you read it already):

1) regedit from the run menu.
2) goto HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE-10318}
3) Export this key so you have a backup of it. (I know this solves the MSbackup but I don't know if other problems will pop up.)
4) delete the key "UpperFilters"
5) re-boot
6) My computer did a "Found new hardware" when it re-booted and required another re-boot.
7) Go ahead and re-boot
8) Run your backup software as ususal.

If the above doesnt work:

You can download the latest version of MbrFix from http://www.sysint.no/en/Download.aspx

1. Reboot from a floppy or CD so we're not changing the MBR while Windows is running. (I'm not sure this is required, but it's what I did. I am very happy with the BartPE boot disk from http://www.nu2.nu/pebuilder/ - it creates a bootable CD with a pared down version of Windows on it. I ran MbrFix from a floppy after BartPE started up. I'm pretty sure any DOS boot disk would do.)

2. Just to make sure drive 0 is the right partition to work on, run the command:

Code:
MbrFix /drive 0 listpartitionsExamine the results to make sure that the drive has the boot partition and is the size you expect.

3. Again, to be safe, tuck away a copy of the current MBR with the command:

Code:
MbrFix /drive 0 savembr BackupMbr0.bin
4. The key step is to generate a new signature for the drive with:

Code:
MbrFix /drive 0 generatesignature
5. Reboot from your hard drive.

6. Windows will detect this as a new drive and ask that you reboot. Reboot as suggested.

Instead of doing the above, You might also be able to run a fixmbr command from recovery console:
