I would like some opinions on this problem before I tell the guy the drive is bad. Is it possible that Seagate's drive diagnostic utility may report a bad HDD because of data/controller corruption? I know a lot of those SATA controllers are having problems right now.... Problem: System will not boot into Windows XP anymore. Worked for a month fine, but finally crapped out. On bootup, it displays the XP logo and blue screens when it loads ntfs.sys. Symptoms & Info: Attempting to install 2000/XP on this system fails. (Pre-installation blue-screens at ntfs.sys), depsite having the latest and oldest drivers available. BIOS of controller and board have been flashed to latest. Controller works properly in device manager when XP is installed on IDE. Computer does the same thing with a different controller (same chipset) and same SATA HDD. A different system with an alternative controller (same chip) does the same thing with the drive plugged in. Both systems work when the drive is NOT plugged in. Drive works in Windows 98, but since it cannot mount NTFS volumes.... Who knows. Seagate Seatools claims the drive is defective (fails SMART tests).
