The Partition formats are different on W2K vs. NT4.0. If you attempt to
write to a W2K partition with the current Linux NTFS driver - YOU WILL
CORRUPT THE DRIVE. You might be able to mount it and read from it with
the current code (some W2K configurations won't work though), but you
should not attempt to write to it. The formats of a W2K partitions are
using the Veritas Volume Manager Stuff they developed for W2K. The
obvious fix is for someone to study NT4.0 vs. W2K and add the necessary
support to **NOT** stomp on the database section Veritas stamps on the
W2K partition -- if you overwrite it (which you do -- you think it's
free space) -- W2K will be toast the first time it tries to mount the
volume after Linux has corrupted it .......
