I ran Dell's diagnostic utility, and it failed on the hard disk check. It gave me an error code of 2000-0151. I also tried booting a linux live CD, and it took a long time to start up. It kept giving the error message "ata1: COMRESET failed (errno=-16)", and I heard some strange clicks afterwards, but it eventually started up. It took much longer than usual to mount the hard disk, but strangely enough I was able to get at least partial access to the disk. It froze when trying to access one of the folders, and after a while it clicked again. gparted couldn't detect the hard disk.
Is there something I can try to fix it? Or does it have to be replaced?
EDIT: Also, in the boot device menu, the hard disk does not appear.
EDIT2: I can no longer access the hard disk in any way from within linux
