What did I do?

This is on my newly upgraded Vista to Seven desktop HP. When examining the 'tree' with Windows Explorer each Drive or Removable Disk used to be identified by the title of the drive/disk or partition, i.e.: Programs (E). I just noticed today that only the title is now used and the identifying letter in parenthesis (E), for example, is missing. This is also true when using xplorer2, a different file manager. This makes it difficult to identify the removable disks, in particular, but that letter is important for me as it identifies the partitions as well. The same function on my new 7 laptop shows these with the accompanying letter. What did I turn 'off' on the desktop and where? Thanks

[Start] [Control Panel] [Performance and Maintenance] [Administrative Tools] [Computer Management] [Storage]

Right-Click [Disk Management] hit Refresh and also try Rescan disks and see if it works.

That did the job Peter. Thanks to all that responded!
