Trying to mount my old windows NTFS partition on new Xubuntu install.

The device '/dev/sda1' doesn't 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?

OnTrack disk manager (OnTrackDM6) was/is special code to overcome computer BIOS hard drive size limitations.

If you add the following kernel option to the boot loader you should be able to mount the NTFS partition.
sda=remap63

However, I do not know if the ubuntu default kernel includes this option nor if it works with any drive that uses the SCSI subsystem i.e. is referenced with a sdx device ID. From what I remember you need to use the ontrack software to remove the MBR special code.

This seems a little too advanced for my newbieness

Here is my /boot/grub/menu.lst, what line would i have to edit, and how?

You can use any text editor like kwrite, emacs or vi etc but you must be root to edit menu.lst.

BTW this will not work with a USB enclosure.

Still can't mount the disk. Any clue what to do ?
