Hi georgesjeanandenis,

That code means, "no drive detected". I know, so helpful. :emotion-18: The next step is to remove and reseat the drive, which you've done unsuccessfully.

Here's what I would do. With the hard drive in your desktop, run the Dell diagnostics on the laptop drive. Or you could run the WD lifeguard diagnostics (whatever they call it).

Thank you so much for your quick answer. I will try that and let you know....

Set the CMOS TO ATA mode in the D830 and reinstall windows. SATA Operation = ATA

It will not see the drive WITH SATA Operation = AHCI

You receive a Stop 0x0000007B error after you move the Windows XP system disk to another computer

STOP: 0x0000007B (0xF741B84C,0xC0000034,0x00000000,0x00000000)
