|Look in Disk Management to see how the drive is listed there. |
While johnr is correct, the cost to recover professionally may diminish the importance of the files in question. I suggest you first answer my question. Then you could try using file recovery software.
That shouldn't harm the drive unless there is a mechanical problem, which could be made worse by running the drive weather you access it or not.
Below are some links to file recovery programs. If the disk simply has a problem with the file structure a program called testdisk may be able to fix it. Testdisk is a powerful utility and shouldn't be run before reading all the tutorials. Links to all ard below.
PC Inspector (freeware)
Zero assumption Recovery
The demo is limited
It will only recover 'up to' four folders per run
But you can make multiple runs
IMO the best, but not free
