Chkdsk (Chkdsk.exe) is a command-line tool that checks volumes for problems. The tool then tries to repair any that it finds. For example, Chkdsk can repair problems related to bad sectors, lost clusters, cross-linked files, and directory errors. To use Chkdsk, you must log on as an administrator or as a member of the Administrators group. You can also run Chkdsk from My Computer or from Windows Explorer. You also need to repair your windows registry to sppedup your computer.
chkdsk /r Locates bad sectors and recovers readable information. chkdsk /f Fixes errors on the disk. The disk must be locked. If chkdsk cannot lock the drive, a message appears that asks you if you want to check the drive the next time you restart the computer. chkdsk /p Performs an exhaustive check even if the drive is not marked for chkdsk to run. This parameter does not make any changes to the drive.
Chkdsk (Check Disk) is a utility in Windows that is used to check the integrity of the file system and file system errors on a disk. It helps to diagnose and repair disk-related problems to ensure the system runs smoothly and to prevent data loss due to disk errors.
Well, you can try running chkdsk, a DOS program included on all versions of Windows. Open up a command prompt window, called cmd.exe. Type that in a run box, and a black-and-white window will open. There will be text that says C:\Users\you> or something like that, if on a Vista computer, or C:\Documents and settings\you> if on XP. Type: chkdsk /f This starts the chkdsk program, and the /f is a switch meaning to fix any errors. If that doesn't work, then it might not be easy to fix. You could try looking for data recovery software using a search engine such as Google or Yahoo. But I don't know how well any of these steps will work.
/F fixes errors on the disk and /R locates bad sectors and recovers readable information
