hello i recently find a hard disk from my friend western digital wd5000aakx caviar blue i already have seagate 500gb sata hard disk when i install the new western digital hard disk and goto bios its showing the error check attached images
It looks like the drive is shot to me.
The best you could do is probably run a check on the disk and try to repair it, without any guaranties you may be able to get it going.
