A gateway computer P4 1.3 ghz, 400mb ram, windows xp pro sp2. A wd1600BB hard drive that has been working fine for over a year. Turned it on today and had a message saying: drive read error, press ctrl + alt + del to reboot. Downloaded and booted from floppy, the WD diagnostics. No errors on the drive. Ran HDD regen program, no errors. Booted from xp cd and ran recovery console, chkdsk /r. Errors found and recovered. Still get the drive read error on power up. Drive appears configured correctly in CMOS. Attaching the drive as a slave works, as I'm able to see the apps and data. Any clues to get this drive booting on it's own, greatly appreciated.
