repairing HDD too costly. better get a new one. doesnt cost u much.

@~hunter~
always what? restart ah? try change ur friends hdd jumper. remove the jumper if there is. n chk the hdd cable. connect ur friend hdd to slave cable. NOT the master cable. try it. might solve it.

burn HDD mobo can send to RMA o not? if can, just send it. others, get a new one. nothing much can do. if can send to RMA, u r lucky. but ur HDD have to be under warranty la.
