That's the same problem as having a NT disk that doens't boot ...

What you can do?

A.
You can create a "clean" NT installation on another hard disk, then install the disk with your information. This way you can read all your files. Or if you have a "spare server" you can install the disk there.

Disadvantages:
a. You lost the installed software (i.e., you need to reinstall all server applications).
b. You lost the drivers for specific hardware you may have, so you will need the original disks or download them if possible from the net.
c. You need to recreate all your security structure : user accounts, permissions, shares, etc.


B.
You can use a Linux machine for the same purpose, making sure your linux box can read NTSF.
Disadvantages: same as above.

C. You can use Partition Magic to convert your partition to FAT32.
Disadvantages: same as above.

So whatever you decide, is a painfull decision... sorry.
