  I have a Dell 2K3 server. When I put a external USB hard drive on it I get the notification down by the clock that new hardware was found. External hard drive found. Device is ready. Then it disappears. The safely remove hardware icon shows up and disappears right away and the drive is nowhere to be seen. Am I missing a service of something?

Do you have any mapped drives on the system? Its possible that there could be an existing drive letter conflict with the USB drive. If you open up disk management you can view all active disks and if necessary change the drive letter for the usb drive.

How about in device manager any yellow exclamation points under the usb devices? Have you tried rescanning the hardware for changes in device manager?

Not yellow exclamations. Nothing. The first thing I did was pop it on another computer. Works like a charm.

Hi,
First put the USB Drive on other computer and format it to NTFS file system then connect it to the server 2003 and you will see the drive without problem.

Jim,

Have you checked Disk Management after the drive is plugged in?

Control Panel -> Admin Tools ->  Computer Managment -> Disk Managment -> Is your drive listed?  Is it formatted?  Is it showing at all?  Perhaps it has a conflicting drive letter?  Drive letters are dynamically assigned, but who knows... It's worth looking at.

What is the size of the external drive?

  The Serverworks USB ports were too old. Replacing them with a USB interface card did the trick.
