Hi, I am trying to upgrade my Seagate 250gb drive with the above. The WD drive is recognised as an external drive attached via USB. The original Seagate is recognised in BIOS. I am using Vista sp2 on a Dell 1525 using AHCI BIOS version A11.
The WD drive when inserted into the laptop is not recognised in BIOS., although as I said it is recognised when attched via USB.
