Depends on how you cleaned things up here. If it was through something like Disc Cleanup then not it wouldn't have deleted anything but a Registry Cleaner very well could have.
Instead of looking in Device Manager look in Disc Management and see if it appears there. If it does look at what is shown. I'm guessing that it will appear as RAW and this comes about because the user [b]Has Not[/b] used the safely Remove Option available under Vista before either unplugging the drive or turning off the computer.
When you tell the computer to shut down it doesn't dismount any External Drives and position them for a Power Down it just cuts the power tot hem and they have to fix themselves. The same thing happens when you unplug them without using the Safely Remove Option.
The solution here is to Open Drive Management and format the drive so that it is usable again as the Partition Tables have been corrupted.
If there is Data on the Drive that Must be recovered you should send it away to a Data Recovery House and let them recover it as you run the risk of destroying Data if you do the wrong thing.
However if it would just [b]Be Nice[/b] to recover the Data you can use one of the many Data Recovery Programs available any will work but the ones that Rebuild the Partition Tables will be the fastest.
Here is a short list of the better ones but it is by no means a complete list of all the available software.

While the last 2 are from the same company they are very different products. Win Hex should only be considered for use by someone who knows Hex Inside Out while Davory is a great cheap General Purpose Application.
Personally I prefer the On Track Option but it's anything but cheap. However because I use this type of software a lot it's paid for itself many times over by now, for a cheaper option Spin Rite from Gibson Research or Stella have both very good reputations by other TR members.
