Ubuntu

change drive permission

Asked by Randy Williams

I have a second SATA hard drive installed and formatted, ext2. The ownership shows as "root" in the drive properties. I want to change permissions on the drive to be able to use it. I tried the console command, sudo chown username:username /path/to/file, but I am not having any success. I don't know what I could have done wrong. I am cautious when it comes to using the command line terminal. The more I use Ubuntu, the more I hate to use Windows.

my windows partition is also shown as owned by root, but i can still use it. Are you sure you can't use it. Another thing: I don't know how big your second hard drive is, but it would be better if you format that on ext3 file system. Because of the jornaling feature, the ext3 is a more secure FS.

I don't see the drive listed in this output. I see sda partition 1 and swap partition 5, but no sdb.

I used the following commands to fix that:
cd /drive/mount/point
sudo chown -hR root:plugdev ./
sudo chmod -r 775 ./

You need to add your drive to fstab.

enter the following command in a terminal

ls /dev/disk/by-uuid -l

grab the UUID pointing to the partition you want to mount. Then create a folder wher you want the partition to be mounted. FInally enter the following line in the fstab

UUID=<the UUID> <pathToTheFolder> ext3 defaults,errors=remount-ro 0 2

save and close. enter the following command

sudo mount -a

and you're done !

You can now define permissions using chown and chmod
