Backup Hardware Error 20/40 Dat

Using Windows 2000 Built-in Backup utility, when I run a backup to tape that takes more than a few minutes, I get a "Hardware Error" or "Hardware error writing to device" form Windows 2000.
I am using the Compaq 20/40 DAT that was supplied with the server and have installed the latest available driver from Compaq.
I can backup smaller numbers of files.

Following is Backup Error log for the faied backup:

What is the firmware revision on the tape drive ?
Have you run diags on the tape drive ?
What brand / type of types are you using ?
What controller is the tape drive attached ? what port ? are hard drives attached to same channel ?

Re: Backup Hardware Error 20/40 Dat

I had a similar problem with HI DDT connected to an Adapted 2940 SCSI controller. To solve this I down loaded the driver for the SCSI adapter from Adapted and replaced the Windows 2000 SCSI driver with this one.

Good luck
