NTFS Drive Wont Mount

[couverman]

I have a Windows XP system that i am trying to copy the ntldr file back to the system so that it will boot, i am using Knoppix Live CD.

When Knoppix loads, I see the HDD on the desktop When i double click it I get -

Could Not Mount Device. The reported error was mount: I could not determine the filesystem type, and none was specified

fdisk -l shows:

/dev/sda1 * 2 30393 244123740 44 Unknown

I run:

mount -t ntfs -o user,umask=0222,nls=utf8 /dev/sda1 /mnt/windows

and get the error

Bootsector checksum failed
Failed to startup volume: Invalid Argument
Failed to mount ' /dev/sda1': Invalid Argument
The device '/dev/sda1' doesnt have a valid ntfs
Maybe you selected the wrong device? Or the whole disk instead of a partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?

This is a mission critical PC and really need to get it back up and going. Any help would be greatly appreciated!

"/dev/sda1 * 2 30393 244123740 44 Unknown" is the clue.


the type of filesystem should be in place of Unknown .... It looks to me like this partition has been damaged pretty severely.....

There is probably a way to recover it but Im not really sure how.

Good Luck!
