i have 2 hard disk 250 gb seagate and the problem is with 500gb seagate hard disk the problem is when i start the computer bios show both hard disk but my pc always hang at welcome logo so i restart my pc and the bios only detect my 250gb hardisk and if i completely turned it off then bios can again detect both hard disk but again same problem
note:- when bios doesn't detect my 500gb hard disk i can still see that its processing or vibrating one of my friend suggest me that it is the problem with pcb of the hard disk
