Marvin Clapp. Hotswapping is dangerous to the media. I found out that this time, the problem was in Windows. The drive G was turned off. I used tweakui to turn it back on.
It is working fine now. Thanks for the input. Windows Server has a tendency of attempting to assign a drive letter to the USB hard drive that is already in use. You will then see a place to change the drive letter. You problems are not resolved. The operating System will assign the letter of your choosing and from then on, you will have total and complete access to your External Hard Drive.
Also, the operating system will indeed remember the letter that you assigned to it and when you unplug the hard drive and plug it back in, the system will assign it the same letter again.

Some other things that we have done: - replace the motherboard same model - tried an add-on PCI USB card - tried an add-on eSATA card and drive this was the showstopper that caused us to use the workaround in my second post So, which driver s should I roll-back on a server that has been in service for 2 years now and otherwise runs fine?

I didn't have access to a Knopix CD, so I'm not sure what the results there would be. And I did not want to muddy the water with this in my initial post, but the server I posted about actually experienced a catastrophic crash right before I made that post and has been replaced. Once the brand new replacement server was set up and the USB drive with the most recent backup was connected to it, it began exhibiting the same symptoms.
As before, that same drive can be connected to an XP Professional workstation without experiencing the same issues. I thought about malware, but I can't find any evidence of that and the drives have frequently been reformatted before use.

If you are running Windows Server and you are wondering why your USB Hard Drive is not seen by the Operating System after you plug it in, here is the answer to this common problem. Windows Server has a tendency of attempting to assign a drive letter to the USB hard drive that is already in use. You will then see a place to change the drive letter. You problems are not resolved. The operating System will assign the letter of your choosing and from then on, you will have total and complete access to your External Hard Drive.
However, it then opens the Found New Hardware wizard and looks for a driver, which of course it doesn't find. The drive shows up in Device Manager with a yellow question mark, but does not show up in Disk Management. The same thing occurs with a WD usb hard drive. I ran updates last night but am still having the same problem. Any ideas?
