USB external Drive failure with Event ID 51 followed by Event id 11

I am running Windows 2000 Server SP4 on a Proliant ML350.  I have always backed up my critical data using Retrospect when suddenly, I started getting delayed write.. errors with Event Id 51 followed by Event ID 11 (lots of them) in the System Log.  Apparently the external USB drive I am backing up to was failing.  I replaced the drive with a brand new external drive and the same thing happens.  I continue to get these errors regardless of the USB external drive I use.  This problem even occurs using NTBACKUP.  The only way I can bring up the USB drive after the failure is to eject it, power down the device and power back up.  Even then, the USB drive MAY or MAY NOT be corrupt. About half the time the USB drive is corrupt and requires reformatting.  I dont want to mess with the system in fear of losing EVERYTHING, yet I am in a real bind, as I cannot back up any of my data.  PLEASE HELP!!

Event Id 51 is a failure to write to the device, Event 11 is failure to communicate at a driver level,
Most likely the drive itself died.

Have you tried to remount the drive in a different enclosure and try again?

I have tried to attach several external drives with the same result.  This is why it does not appear to be a drive issue but rather a system or controller issue.  Also, if I disconnect and reconnect the external drive, the drive restores without issue but data on the drive is corrupt.  If I reformat the external drive everything is fine.  So I don't think this is a drive issue.  It seems that this problem comes into play when writing large amounts of data to the external drive.

you could be having a usb communication issue, or you could have an interrupt conflict with the usb bus.
Try setting in the bios, the irq to 11 or 10 and try to make it not share the irq.

That's where I would start.
Next I'd try turning off usb in the bios and add an add in card and see if the problem persists.

Did you get a chance to change the interrupt on the bios?

Sorry, I had an issue with my membership.  There is definately something with the USB controller because I have NO problem when accessing the external drive across the network attached to different computer.  Now, I am not sure where or how to proceed with the USB controller.  Should I still try to change the interrupt on the bios?

They are cheap and easy to replace. I'd replace it rather than mess with a bad controller. Just remember to turn it off in the bios before inserting the card, no sense in using wasted IRQ real estate.
