hi,
For me Tweak software was not worked but restarting three to four times it worked for me - I didn't even change any settings just installed the tweak software.

hi,
I would also suggest the Knoppix disc for this too -- it's an excellent tool for eliminating possibilities of OS problems. Sometimes when the computer unexpectedly restarts, it has trouble restarting. Instead of taking the power cable out of the hard drive, just power the system off for ten seconds and power it back on and see if it starts correctly. You may also want to turn off any power saving functions in BIOS

hi,
Try to installed or used another external storage device in that port.

try to check the setting in disk management.
Click Start>>right click My Computer>>Manage and then on the left-hand side click on Disk management.

If this is an IDE hard drive, make sure you have the jumper setting right. It may have been changed to "slave".

As a final test, try the drive in a computer that isn't having issues. Perhaps your PC's problems go deeper than the hard drive.
