Code:
/dev/sda1 /mnt/xp ntfs-3g rw,nosuid,nodev,uid=jschiwal,fmask=0177,dmask=0077,utf8 0 0
This is the fstab line that I use for my windows (ntfs) partition. Use your own username for the uid= option of course. I installed the "fuse" and "ntfs-3g" packages. First you need to modprobe the fuse module. After that you use the filesystem type "ntfs-3g". This will give you read/write access.
