Cannot Open Disk Volume

My daughter purchased a HP Pavilion laptop about 3 months ago.  It runs Windows 7 Home Premium (64-bit) and has a single HDD but with a pre-installed reserve area (~ 20GB) for emergency recovery (designated as drive D:).

On bootup it reaches the standard Windows 7 “Starting Windows” screen with the 4 'orbiting' colours meeting in the centre of the screen, but then reverts to a black VGA text-only screen with the following error message:

Checking file system on C:
The type of file system is NTFS.
One of your disks needs to be checked for consistency.  You may cancel the disk check, but it is strongly recommended that you continue.
Windows will now check the disk.
Cannot open volume for direct access.
Autocheck cannot run due to an error caused by a recently installed software package.
Use the System Restore feature from the Control Panel to restore the system to a point prior to the recent software package installation.
An unspecified error occurred (766f6c756d652e63 3f1)

If you press a key to skip the disk check Windows 7 starts up fully and works without a hitch, and shuts down normally.  But every time a reboot is done, the above message repeats.

I’m wondering if the suspect disk is the D: system recovery disk, on the basis that the C: drive seems OK and the part of the message which states “Cannot open volume for direct access.”

Any clues anyone?  I don’t like simply ignoring messages like this for too long.

Thanks.

"Boot into Safe Mode. Turn the computer off (cold boot), start backup, before operating system loads, press F8 on your keyboard, when the Advanced Boot Options menu appears, use the up and down keys and select Safe Mode.

(Booting into safe mode may take several minutes.)

When booted into Safe Mode, log in, click Start
Type: CMD, from the results, right click CMD
Click 'Run as Administrator'
At the Command Prompt, type: chkdsk /r /f

When you restart your system, your computer will be scanned for errors and attempts will be made to correct them."



MAKE SURE YOUR DISK IS NOT FULL!!

Run a "Startup Repair" as follows:

    * Shut down your computer
    * After pressing the power button to start, start tapping F8 (about once per second)
    * A screen will appear with "Repair Your Computer".  This should be the first option - hit enter to select.
    * A dialog box labelled "System Recovery Options" will appear.  This says "Select a keyboard input method".  Press "Next>" for US.
    * At the next screen select your login name and enter your password.
    * On the next screen, select the first option: "Startup Repair". (There are other handy options here.)

For me it said "Attempting repairs" followed by "Repairing disk errors".

 

Once it was done, there was an option for "Diagnosis and Repair details."

For me this said:

  "Root cause found:  System volume on disk is corrupt.  Repair action: File system repair (chkdsk). Completed successfully."

 

I rebooted and everything was fine.

 

An easier option might be to schedule a chkdsk directly.  I ran a chkdsk without repairs earlier and it claimed everything was fine.

 

To schedule a chkdsk:

    * Press the Windows "Start" button
    * Select "Computer"
    * This lists Hard Disk Drives - click right on C: (the most likely suspect)
    * Select "Properties"
    * Select the "Tools" tab
    * Select the "Check now..." button
    * Leave the option checked for "Automatically fix file system errors"
    * Press "Start"
    * It should prompt for a reboot, after which it will check and fix your drive.

If that doesn't work, also try checking "Scan for and attempt recovery of bad sectors".

 

With neither option checked, it scans for errors without fixing.  As mentioned, it reported no errors for me, but perhaps it needs to scan after rebooting and this requires checking the first option.

 

I would also recommend that you order or create your recovery discs.  For the dv8, under "Support & Drivers" I was able to access a manual called "Backup and Recovery User Guide".  This has a section called "Creating recovery discs."  You might also find this on your computer by search for "creating recovery discs" under "Help and Support".

Thanks Nivlesh (and also Mr fixit22).

The only 'trick' was that pressing F8 did nothing.  The system took this as simply pressing a key to abort chkdsk running.

However the HP (it's a dv6) has a message at the bottom left hand corner of the screen when first POSTing which says to press ESC to access a menu.  This gives the repair (and other) options.  I'd describe it as an alternative interface to Microsoft's F8 option - a special HP-branded approach.

Anyway, chkdsk did its thing and the message no longer appears before Windows loads up.

Super, thanks.
