having trouble mounting my hard drives

I tried mounting my harddrives using mount /dev/hda1 and it says can't find /UnionFS/dev/hda1 in /etc/fastb or /etc/mtab. I looked on tux files and it says to do it mount /dev/hda1 /mnt/hda1 and it told me only root can do that so I used su to get into root and it used the command again and it said mount : /dev/hda1 is not a valid block device

how do I mount my harddrives? I have 1 laptop hardrive split up into 2 partitions and 2 usb hard drives, 1 partition each, all NTFS formatted, Preferably I would like to mount them NTFS writeable

I could use a little help, Im trying to get used to using linux as I would like to do a dual boot with linux cause I feel windows is slow, so currently I am experimenting with Knoppix 4.0.

Any help would be appreciated, please pity those of us who are linuxtarded

update: Ok i just found the Fstab mount manager, and found all my stuff its already mounted, now how to I make it so that it is writebable, or how do I use the NTFS emulation thing so I can write to it?

When you mount a hard drive you must give it several different parameters. You give it the device (e.g. /dev/hda1), the mount point (such as /mnt/myharddrive, which MUST exist in advance), and the type of filesystem (e.g. -t ext2).

e.g. mount /dev/hda1 /mnt/myharddrive -t ext2

NTFS writing can be enabled in 2.6 kernels, but it is limited. It works if the file size does not change.

The other way is a program called captive ntfs. I have not personally used it, I just converted my windoze 2k partition to FAT32 instead so I could read and write it.
