Trouble with mounting hard disks

[Rekkr]

Two problems.

First, I am trying to mount a hard drive which I put in AFTER the installation of Linux.

When I use:
mount -t <filesystem> /dev/hdb1 /mnt/path
Everything seems to work fine, until I go to access the drive I just mounted. I get an error saying I don't have the proper permissions. The same thing happens when I try to mount the partitions through the Control Center.

The other problem is with the drives I already have mounted (they mounted themselves on their own after the installation of Linux), I cannot change anything on the drives. I can't delete or add anything to the drives but I can open the files already on the drive. What can I do so that I have full read/write access to my mounted drives?

By the way, all the partitions which I am trying to mount are either NTFS or FAT32, both of which Linux (or Mandrake 10.1 at least) can support.

(EDIT: I'm pretty sure the reason I can't access the mounts I create through the BASH prompt is because they were created by root. When I try to create a mount while not being root, I get "only root can do that". So all I need is a way to change folder permissions...)

umount /mnt/mountpoint
mount -t <fstype> /dev/whatever /mnt/mountpoint -o rw

Thanks, but it still doesn't work. Same error message saying I don't have the permissions.

NTFS is only has read fully suported, write is a very risky business and can lose you a drive.

To mount readonly ntfs:

su
rootpass
chmod 444 /mnt/path

to mount fat32 which is fully suported in linux:

su
rootpass
chmod 777 /mnt/path
