Using ubuntu hardy
To check the filesystem: sudo fsck /dev/sdb1
To mount it
To check what the filesystem table says about it sudo gvim /etc/fstab
To make it read-writable chmod 777 /media/disk
To mount sudo mount -rw /dev/sdb1 /media/Nabla -t ntfs
To unmount sudo umount /media/nabla
Might need to make the Nabla directory first.
To mount ntfs drives gksudo ntfs-config (be careful with this, my advice is only to mount for special purposes or read only. If your data is not very valuable then go for it).
