I have a Western Digital Caviar Blue / SE / SE16 (SATA II) hard drive. A few weeks ago I got bluescreened but didn't think anything of it since I rebooted and experienced no further problems.
Last week I came home to find my PC hanging on the HP Invent BIOS boot screen (it had been fully booted when I left). I hard-booted the machine, and it booted fine. The next time I booted, the PC ran CHKDSK automatically. CHKDSK ran to completion, but on automatic reboot the machine hung on the HP Invent boot screen again.
This has happened numerous times in the past week. CHKDSK runs to completion and doesn't find any bad sectors or other errors, but then the machine hangs on reboot.
I updated my backups of everything. I was able to run Windows Backup and Restore and create a new image file, but the log showed numerous errors indicating a bad disk.
I downloaded the manufacturer's diagnostic tool here:
The quick-check showed no errors. I am running a full drive scan but it hasn't yet turned up anything. The drive is not making any odd noises.
Is this a bad hard drive or is it something else? The bluescreen and the boot failures seem to indicate that the disk may have problems, but thus far I have not been able to find any errors via any diagnostic tools.
