    Go to computer management...there you can see the volume with the hard drive number i.e  hardisk0.

    You can recongnize from there......its is only easy and perfect step to do so........

    I don't know much about the HP ProLiant, but I've had similar issues with a desktop PC (same error). The problem was down to TWO issues. First of all the controller (the board on the hard drive itself) WAS at fault, AND the SATA cable. When I changed the SATA cable, I was able to get 99% of my data off of the drive before sending it away for warranty replacement - but I assume you have a RAID configuration so a simple drive swap should suffice.

    As for which drive number, are there any HP diagnostics you can use to identify the drive? I know that Dell have their own OpenManage suite and you can use this to make the LEDs of each drive blink.

    you may want to try to check and fix problems by running from a prompt command:
    “chkdsk c: /f /r”
    please note that tha /r parameter will make this procedure last for long time (depending on your disk) and shouldn't be stopped by user before end.
    The parameter “/f” tells chkdsk to automatically attempt to “fix” any problems it may encounter, and “/r” tells chkdsk to do a very thorough five step deep scan for bad sectors and physical damage while attempting to recover potentially unrecoverable information.
    Alternatively you may want to first run the command without the /r option.

    hope this helps

    normally if hard disk is faulty, it shows red light blips on the hard disk.  I will change the hard disk and the cable, I hope that solve the issue.

    ... not always true ... depends on what is faulty on the HD.
    chkdsk will inspect sectors and cilinders: I can assure you that I have solved a few problems with that command, I'd give it a try if I were in your position

    hope this helps
