It's drive letter issues.
Others report adding an USB 2.0 Hub helps.
At least it's a work machine and you can get your IT staff on it.

Ok, I tried looking for something out there that could help, to no avail.
So here it is:
At work I have a Windows 2000 NT computer. I have two external hard drives attached to it - both WD. I just got a LaCie (sp?) external. I had to reformat from FAT32 to NTFS....
Basically, the computer reads the drive when I plug it in, but in turn the computer no longer properly reads the other two externals - suddenly I can access the files and sometimes I can see the folders.
When I unplug the new drive (500mb, and the others are 250 and 320 respectively), the other drives become readable again.
So - how can I get all three to run and be usable at the same time????
