i have a windows 2003 std server (w/sp2) with a new internal ide quantum travan 20/40gb tape drive (firmware 3.10c) (new - quantum 20/40gb tapes) that appears to be causing the server to restart intermittently. i'm using the windows ntbackup.exe utility to perform all backup procedures. the tape dirve is on the same ide channel as a standard cdrom. the server restarts during backups jobs and while just spinning the tape up after insertion. i downloaded the latest drivers from quantum's site for win2k3 and installed them. i have downloaded taperx diag utility from quantum's site and tested the drive and it tests good. the drive works fine in another computer with no failures (five consequetive backups). the win2k3 server had a travan 10/20gb drive in it to begin with and it was having problems with a small belt coming off so it was pulled out and replaced with this one. no other problems existed with the 10/20gb travan that was in the server. the memory in the server has also been replaced and tested with memtest. i have pulled the cdrom off the channel and still had problems. i have ran two backups to another peer machine with no problems. i have not replaced the ide cable nor the power supply in the system which i have small suspect for the problem. the 2 seagate sata hard disk drives run off a pci sata raid card and are running raid 1. i have run a disk check on the drive using checkdisk and there appears to be no problems with the drives.
