This is a video on how to either A: Recover lost data on a hard drive or B: Repair the file system on the disk. Using Command Prompt I'll guide you through the steps to do this.
SATA IDE 2.0 USB Reader
Power Supply with SATA Conversion if SATA Drive
Step 1: Take the Hard Drive (HDD) that you wish to Repair or Recover and hook it up to the SATA IDE 2.0 USB reader and connect the Power for SATA to the Drive (If not a SATA drive and just IDE Power is supplied through 2.0 USB) and plug the 2.0 into the High Speed USB port.
Step 2: Click on the Start menu and "Right Click" on Computer and select Manage, once the window comes up select "Disk management" and locate the HDD you plugged in and find out the Drive Path letter, for an example mine in this video was G:, yours might be different.
Step 3: Open up the start menu and go to the search tab and search CMD and you will see Command Prompt pop up in the window above, Right Click on Command Prompt and Run as Administrator. Select Yes at the Prompt and it will open Command Prompt.
Step 4: Your going to perform a Check Disk so in order to do this type the Command CHKDSK DRIVELETTER: and hit enter and it will perform the Check Disk, once the check disk is done it will tell you if you need to fix the File System if so you will need to run the Check Disk again only this time type CHKDSK DRIVELETTER: /F once that is complete it will tell you if it was able to repair the problem and now we can Recover
Step 5: Type the Command RECOVER and you will see This: RECOVER [Drive:][Path]filename This is a guideline just simply replace Drive: with the Letter of your drive (using my example G:) and the path with where you want to recover for an example if i wanted to restore drivers it would be RESTORE G:/windows/system32/drivers.
Step 6: Once you've recovered your files your all set to go and you can recover multiple files and paths, If you have another computer use the files and paths as reference to help you choose the proper commands
