Windows 7: Unmountable Disk Volume and BSOD

Unmountable Disk Volume and BSOD

I have a Compaq Presario CQ70 Notebook PC, upgraded from Vista to Windows 7.

This morning when I tried to start up windows I get a Windows Error Recovery message with two choices: Launch Startup Repair and Start Windows Normally.
With repair it starts loading windows files and then starts loading windows, but It gets interrupted and turn black with a mouse pointer. ctrl+alt+delete does not respond nor does sticky keys (5xshift).
When I start windows normally, It does load windows but gets interrupted again but this time with a blue screen what says Unmountable Disk Volume.

However, I am able to go into BIOS and advanced boot options.
I've tried Safe Mode but I get the blue screen with the UDV error again. I've tried using a bootable repair cd, it does respond but after loading the files I get the black screen again. I also done the hard disk self test which I failed saying to replace hard disk 1 but I passed the SMART test.
Is the hard disk completely broken or will I be able to safe my files on it?

Can anyone help me with this problem?

If you have access to another computer, go to the website of the manufacturer of the hard drive and download a disk drive diagnostic test.Then burn as a bootable cd and run on the computer with the quetionable hard drive.

Do you know where to find the manufacturer of the hard drive?

Go to the manufacturer of your computer and find the model and look under product specifications. You could also look at the drive by opening the case. It's best to use the test of the manufacturer but others will also work.

Thanks nickle and theog.

I have a Samsung hdd and downloaded the diagnostics tools, but I had some problems using it. I looked on the internet and was recommended Seatools instead.

I did a short test and a long test which I both failed, and in the long test I had about 90 errors. Afterwards, it told me it has failed some kind of critical test, so I'm going to backup my files using Ubunto and then I'll format my drive somehow and reinstall windows.

Thanks for your help. I'll will keep you updated if anything would still occur.

Failing the test indicates that the hard drive is dying.
You'll continue to have problems with it until you replace it with a new one.

Thanks usasma,

Luckily I still have a warranty for it and should have no problem getting a new one.
And I have my files as well, so I'm not worried about it anymore.

I'm glad to hear that you've still got a warranty, that'll take some of the sting out of the replacement.
Good luck!
