These should help you especially if you have data on it
If you haven't and it offers you the chance to format it, simply do that.
Download the Windows version of TestDisk. http://www.cgsecurity.org/wiki/TestDisk
Unzip the downloaded file to your C: drive and open C:\testdisk-6.8\win > double click " testdisk_win" (the program doesn't have to installed).
A. At the first window select “No Log” and press the <Enter> key.
B. Select what drive to analyse, choose “Proceed” and <Enter>.
C. Select partition type – Intel if it’s a PC.
D. Select “Analyse” then <Enter>. The drive/partition will be analysed.
E. Select “Proceed” at the next screen, then <Enter>.
F. Press “Y” if the partitions were created under Vista – “N” if not.
G. TestDisk should say “Structure OK”. Choose the drive/partition to fix. Then press <Enter>.
H. Select “Write” and press <Enter>.
I. Press “Y”.
J. Press <Enter> and close TestDisk. Reboot the computer.
