I am pretty sure that my hard drive is dead. Vista basically disappeared off the computer and I can't find the C: even with the Vista repair or UBCD - SO, I am looking to replace it. Model: Hitachi HTS541660J9SA00 5400RPM SATA 2.5" .... I have been looking at a WD Scorpio Black 7200 RPM SATA 2.5-inch and need to know if that would work or what I need to look for in making sure it is compatible. Thankss.
