External Hard Drive Permission
I'm trying to change my external hard drive permissions so that I can write to it as well, every time I try chmod (or going through nautilus) it gives me the error of "read-only system file". Any ideas on how to change this? I'm a newbie still so I'll probably need detailed instructions if it requires using the text editors or what not. Thanks

check your /etc/fstab line that mounts the external drive (possibly /dev/sd?) and ensure that it does not include 'ro' in the "options" column (the 4th column) - if it does unmount the drive, remove the 'ro' and then remount and you should be able to add write access using chmod as you have been.

Post the output of fdisk -l command and contents of /etc/fstab file here.

leomburke is correct. In fact, your best bet is to use the mount option 'rw' (read/write), even if 'ro' (readonly) isn't there.

Setting rw to Partitions having Linux based FIlesystem will enable write access to root user only.
One has to take ownership of mount_point to have read/write access of Linux based FileSystems.

I am fairly sure it's not NTFS. I don't have access to the drive until I get home tonight but I am fairly sure I purposely formatted it as FAT. I'll try the suggestions here....I'm not sure why I would have to unmount it, I have never manually mounted it in this distro, I used to have to in FC3 but now it's basically just plug and play....is it a default to have it as ro?

If External Disk has FAT FileSystem then it will default to rw because Fedora support FAT read/write access out of box.
Check the output of fdisk -l command.

I checked the hard drive in windows and it was NTFS....I had to do some crazy stuff to partition it, move all the stuff (almost 100 gigs) to the FAT32 partition, then I deleted the first partition and resized the FAT32 partition....the only problem is it wouldn't allow me to make it more than 195 gigs or so, so I have 55 gigs being wasted....but good news is that I can delete and modify files on the drive now and all of my files were saved (at one point I thought I had lost about 10 gigs of music). Thanks all

The problem with FAT...
..is that it has a maximum file size of 1 Gig, so if you want to be able to store larger files (like video files for example), and also be able to swap the drive back and forth between a Windoze system, then you kind of need NTFS I think. So is there a workaround for NTFS?

Guys, this thread is well over 5 years old so I'm going to go ahead and close it, but if any of you are still having issues with Linux, please feel free to start a fresh thread with details.
