Cannot write to LUKS encrypted hard drive

Nemesissparadise · 04-03-2011, 02:15 PM

I am running Fedora 14 with the Gnome desktop and I have a 1 TB external hard drive that is msdos with approximately 200 gbs of data on it. I can unlock it and even read and copy files to my internal hard drive but I cannot add files to it, I use to be able to. I didn;t think i changed permissions or anything so can anyone advise me how to fix this or should i back up everything on it and reformat it and hope that fixes it?

Is the mount point read write?

Ok I have determined that it is a read only file system but after going to the link I dont understand how that helps me, that just tells me how to encrypt it as far as I can tell. What am I missing?

Create open and close scripts

Create a directory where you want to mount it to and don't forget to give you write permission to that.
openCrypto.sh

#!/bin/bash
sudo cryptsetup luksOpen /dev/sdb1 somename
sudo mount /dev/mapper/somename /mnt/somename

This is what I was thinking about. /mnt/somename permission to a user.
