I am trying to add a new drive to a system but it is not seen by Windows disk manager.
System is Windows XP Pro SP3
Motherboard is ASUS PN5-E SLI.
New drive is Western Digital Caviar Green 2TB (WD20EARX) SATA III. Purchased yesterday.
Drive is recognised by BIOS.
Drive appears in device manager under disk drives and shows status as “This device is working properly”.
Drive also appears in device manager under IDE ATA/ATAPI controllers.
Read Speed test initiated from device manager IDE ATA/ATAPI controllers passes.
Western Digital Data LifeGuard diagnostics recognise the disks and shows SMART status as pass and Quick test passes.
System already has two other HD. WD3200AAKS (320G system drive) and WD20EARS (2TB, SATA II)
I added the 2TB WD20EARS drive in back in June without problem.
I have tried with and without a jumper on pins 5/6 of the drive to force into SATA II mode. Without the jumper the Read Speed test initiated from device manager IDE ATA/ATAPI controllers shows “The current transfer mode is Serial ATA Generation 1 – 1.5G”, with the jumper it shows “The current transfer mode is Serial ATA Generation 2 – 3G”. The test run OK in both cases.
I have tried using the SATA and power cable currently going to the other 2TB drive (WD20EARS) but it made no difference. So it is not a cable problem.
I put the drive into another PC (Windows 7, Gigabyte P55A-UD3P) and it was recognised without problem. So the disk is OK.
I have been looking at this for half a day but no joy.
Any ideas? Something obvious hopefully…
