So i accidently bumped into my computer and my one harddrive stopped working. I cant remember hearing any bad sounds what so ever. So i rebooted my computer, again no bad sounds from the drive, and it spun like it should. In the BIOS it was recognizeable and it could find the info about manufacturer and the size of the HDD. On my desktop however the HDD was recognizeable but there "Space left" bar was gone (http://prntscr.com/683zyx). I am not able to run chkdsk, diskpart, run the disk manager or anything. They would all just freeze. I could not enter the hard drive either.
