I have a 750mghz computer running on windows xp with a maxtor 20gbyte ide hard drive, This was absolutely running fine for years but just recently my son removed the hdisk from my computer and installed it on his friends computer via the cdrom ide without changing the jumper settings which was set to master, he said it was detected on his friends computer as a secondary master and they transferred some game files from my harddisk to his friends comp harddisk. But when he reinstalled it on my computer the hard disk was no longer detected and a message appear DISK BOOT FAIL. I tried to access the bios set up and Auto Detect the disk but it can not be detected , the bios says Primary Master None.I tried to change the ide cable with a new one suspecting that it mught have been damaged during removal but still the disk cannot be detected.
Please help me I have all my important files on this disk .
