there is something built into the new slax (not sure about old versions) that enables this its called ntfs-3g,
it should be run just as that goto run and type :
CODE
ntfs-3g
it should give you access to be able to enable write and read access to the drives
on a note though, slax dosent have the newest version of ntfs-3g, and on their most recent changelog they listed this:
QUOTE
STABLE Version 1.2506 (May 6, 2008) -- Release Notes
* Fix: In certain, rare circumstances, any area of the ntfs volume, except the ntfs boot sector, could get corrupted. The chance for this to happen is higher for close to full disk utilization and using one of the more uncommon, less than 4096 byte cluster sizes. The cluster size is logged under the /var/logs directory usually in the 'messages' or 'daemon.log' log file, as the blksize mount parameter. All stable releases have this issue since version 1.328. Upgrade is strongly recommended from all ntfs-3G releases.
so id proceed with caution as they have admitted to have corruption problems (i personally have never had an issue and have been using ntfs-3g on ubuntu for a while, but just make sure you understand the risks)
