I am servicing an HP dv2125nr notebook computer. The problem was that it came up with a blue screen while booting and said, "unmountable_boot_volume."
I took the drive out and mounted it in my desktop pc via the on board SATA controller. I booted to my system and ran a chkdsk and an anti-virus scan on the notebook drive. It found some problems and fixed them. I put the drive back in the notebook and it started working again. So far so good.
I put the drive back in the desktop pc and made an image backup to my internal IDE drive. Still, so far so good.
I bought a new Fujitsu hard drive off of ebay, received it, and mounted it in my desktop pc thinking I could restore the image file from hard disk to the new Fujitsu drive. However when I powered up the pc, the pc speaker beeped once as it always does after posting, then it froze at the screen where it displays the components attached to the IDE and SATA controllers. After a few seconds, the screen went blank and the system rebooted again. It stayed in this loop until I had to manually remove the power. I was unable to get into the bios settings. If I remove the new drive, of course everything is fine again.
I called Fujitsu and told them the story and they said it could be a firmware problem where it was only designed to operate in certain systems. That was news to me. I never heard of a new, empty hard drive being designed to only operate in specific systems.
Have any of you encountered a problem like this before? I doubt the hard drive is defective but on the other hand, I can't think of any other reasonable explanation.
By the way, if I put the new drive in the notebook and try to boot with a utility cd, the same thing happens. It freezes on the HP logo though it doesn't constantly reboot.
Thanks for your reply.
