I have a Dell 330 Precision with a 18GB Ultra SCSI boot up hard drive (refered hence forth as "Disk C1") connected by an Adaptec 29160N SCSI Controller card. The hard disk, Disk C1, is loaded with windows 2000 Profession SP 3 operating system. There is no other OS but the hard disk has Norton Utilities 2003 and Antivirus. The Norton utilities ran weekly to defrag the drive.
Recently I had a boot-up problem. The boot progresses naturally in the beginning, goes past the bios setup, where it correctly detects the Disk C1. It then goes through the blank screen saying "Starting Windows" and the white bar at the bottom goes through, the black screen. The screen switches to the Windows splash screen saying ... "Windows 2000 Profession, Built on NT Technology". Below the blue stripe there is progress bar about 75% finished saying "starting window....". The progress bar stays there for over 3 hours, and there is no disk activity. The computer fails to boot-up.
I have narrowed the problem to the SCSI hard drive, Disk C1, by trial and error. Replacing the hard drive with another (called Disk C2) and re-installing windows, works and the computer boots up fine. If I have the tainted Hard Disk C1 in SCSI chain (with a different ID setting then 0), the computer still hangs up even if try booting from a good bootable disk Disk C2.
Among other things, I have:
a) Checked the SCSI drive through the Bios for errors. It is error free
b) Tried repairing windows 2000 using startup CDROM containing Windows 2000+SP1 and installing the SCSI driver through F6. Unfortunately the startup proceeds, installs all drivers and stalls for over 6 hours at "Starting Windows".
c) I have tried a bootable disk with Boot.ini, ntldr, ntdetect.com etc. The bootable disk works with a new format scsi (Disk C2) but fails with the old scsi, the Disk C1. Because of the /SOS option the, I could see that the memory was checked fine and it stopped at the "check file system".
d) I have also run the dell diagnostic on the system, all hardware including the hard disk, Disk C1, checks out okay.
I need the data in the disk and would like to know why the disk failed; viral, software or hardware. So my question is how do I get to access the disk? And what could be wrong with it?
