This combination does not work properly with respect to resuming from S3 standby mode. When you try to resume, the drive makes 4 clicking sounds about a second or two apart and then WinXP dies a horrible death (with all sorts of different errors, but most typically "Unknown Hard Error" and/or a bluescreen with stop code d0000144. ASUS tech support is uninterested in the problem. Hitachi tech support blames it on ASUS not giving the drive enough time to spin up after resume.
If this is an important consideration to you, look elsewhere for your SATA hard drive.
