All partitions missing when copying

Question

I bought a new 320GB SATA hard drive few months ago no recently when i try to copy something to the drive after about 20 seconds the all the partitions in the hard drive suddenly disappears.
The hard drive is not shown in either Disk manager or device manager. To get the HD work i have to restart the PC again.The same thing happens when i try to copy. Even when i play any audio or video after abt 5 minutes i get the same problem.
The drives are NTFS and im running Windows XP.. Xan some one please help me solve the problem??

Answer 1

The problem was the ide hard drive that i had connected, there seems to be a speed issue. Changing the ide to a different sata drive solved it

Answer 2

did you check all the wires ? sounds like a disconnect of the wire somehow ... otherwise the hdd is broken...
