Hi, it sounds like the letter the computer wants to assign is already in use - which confuses it slightly. Do you have any network drives that are mapped...? It could be that the USB drive is getting assigned the same letter, meaning that you can't access it properly.

For example, if your computer has C: and D: drives as HDDs, and also has a CD/DVD drive using E:, your computer will normally try to use F: next - but often companies use this as a network drive, being shared from a server.

As you don't have admin rights on the computer you won't be able to get into computer management to check/change it, so you are left with a couple of options...

1) Get someone who has administrative rights (either on that computer, or on the domain- if applicable) to right-click "My Computer" --> "Manage" and check in the "Disk Management" area and check.

2) If your network drives are mapped through a script, then you can just right-click the drive letter that could be interfering --> "disconnect". This should then allow the USB device to get the letter properly when you plug it back in - if it doesn't automatically gain it. If the mapping was done manually, then you can do the same thing, but make a note of where it maps to, so that you can re-connect it later or give the same location a different drive letter. Just be aware that sometimes, if done manually, this could potentially use a different set of credentials to what you normally use...

The only other alternative I can think of would be to plug another USB device in first, which would attempt to use the letter that it is trying to use already, and then plug the desired USB drive in....
