What to do when a new hard drive doesn't appear

HELPROOM ANSWER You must first enable the SATA interface in the Bios. Documentation is pretty scarce on Bios features related to this, but suggests that 500GB 2.5in drives are supported only where two 250GB drives are combined in a Raid array. To get access to your new drive you may have to install the latest Bios – version F.59 (released in December 2008) is available at hp.com/uk.
