I have a problem, I have a Dell 2600PE which is running 2003 sp2 with a 6 port(2 internal 4 external) USB2 I/O card and installed a Antec USB external HD enclosure w/ a Western Digital SATA 500gb HD. The issue is when I backup my main server to this USB drive the task will some times complete and sometimes fail but every time the drive quits and I have to power cycle the USB drive to get it to work again. Things I have tryed is:
Remove indexing from this drive
latest drivers for I/O card
Different USB cables
Different USB ports encluding onboard USB ports on server
Checking USB enclosure power supply
Changing jumper on drive to limit to 1.5gbs transfer rate
Server has latest bios updates and firmware updates for backplane
I can manually copy large files from drive to this drive no issues. This server is dedicated to backing up our main server. I am using ntbackup on main server to schedule the backup (of which I have never had any issues using before). Log files say cannot open media (if backup fails) or the logs confirm the backup completed no errors but drive quits after operation. Any help would be great.
