[SOLVED] Extra hard drives

[AmpersUK]

I have loaded 8.04 onto my first hard drive. I am not dual-booting with any other operating system.

I want to put some of my data onto my other hard drives.

When I try to copy files over I get an error message. Something along the lines that I don't have permission.

I check the hard drives and find they are owned by "root".

How can I change this so they are owned by my own user name. I am the only user on the computer.

I am using a desktop ASUS with three 500GB hard drives and 2GB of memory.

can you post these

sudo fdisk -l
cat /etc/fstab

can you post these

sudo fdisk -l

I typed these into Terminal and received the following:

And then checked, and get the message that I don't have permissions to copy to the other hard disks.

You just need to add them to fstab and they will mount at boot. Have to make folders for them to mount in and then edit the fstab file.

I will call them respectively disc1 and disc2 - you can change these to more suitable names as long as you change them for the folder name and in fstab - they must match

sudo mkdir /media/disc1
sudo mkdir /media/disc2

Now backup and edit the fstab file

sudo cp /etc/fstab /etc/fstab.2605
gksudo gedit /etc/fstab

Add these lines to the end of the fstab file

/dev/sdb1 /media/disc1     ext3    defaults        0       2
/dev/sdc5 /media/disc2     ext3    defaults        0       2

To check that they mount

sudo mount -a

If all is ok they will also mount on boot.

It is possible to use UUID, install does that by default, as well - trouble being if anything changes with the partition so does the UUID - but fstab would need changing manually. If you want to use UUID run this command

sudo blkid

It will give you a number similar to
UUID=604bb2b5-bc2a-4730-9208-2c50e05816b8

for each of your partitions - where the lines to add above look like

/dev/sdc5 /media/disc2 ext3 defaults 0 2

change the line to be

UUID=longnumberandletterchain /media/disc2 ext3 defaults 0 2

here is how i did mine .. hope it works for u...


Open up a terminal window and run the following command:

 sudo fdisk -l 

this would give u a list of all the drive on ur pc ..
mine looks like this

Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xb61906e5

/dev/sda5 1 6254 50235192 83 Linux
/dev/sda6 6255 6527 2192841 82 Linux swap / Solaris


if u see the drive u wants to mount .. that means u can mount it .. in my case the drive i wanted to mount is /dev/sda1 ...

now once u have seen the drive u want to mount
u now would have to creat a virtual drive .. this is where ubuntu would mount the drive .. (ubuntu mounts all drives in /media)
so u have to create a virtual drive in /media where ubuntu would mount ur drive ... the name of my virtual drive is Data

so in my case i just did

sudo mkdir /media/Data 

make sure the name of the virtual drive contains no special character or space .. very important ..

to give the drive writable partition just do this - substituting Data for what ever name u use-

sudo chmod 777 /media/Data 

If you want to mount your drive right away, and you don’t care if it’s mounted automatically every time you boot - then in terminal run the following command:

  sudo mount /dev/sda1 /media/Data 

now the sda1 in my case would be mounted in /media/Data
to made it to me automatically mounted each time i reboot .. then u need to add the it to ur fstab

run this

sudo gedit /etc/fstab 

add this to the bottom of file

/dev/sda1 /media/Data ext3 defaults 0 0

remember substitute both the name of my hard drive for yours (mine is sda1), and my mount point name for yours. Then save the file.

to make ur drives to me mounted without reboot just do this

sudo mount -a 

they u have it

if u have any problem let me know ..

change the line to be

I tried the first part but got the usual message saying No, and mentioning "backend" whatever that means.

I tried just the first part but got a little bewildered when I got this result:

Hi - you need to post the error messages you get so we can see them please, yea can be bewildering I know

You can use the UUID's instead of /dev/sdb1 or sdc5 when you edit the fstab file.

Are you saying that you get an erro when you try to run the mkdir command?

All 3 of your drives are there - the way it works inlinux is

sda - drive1
sdb - drive2
sdc - drive3

then add numbers for the partitions on each drive

sda1 - first partition on first drive

In your case you have extended partitions as well - to confuse you more

sdc5 is a partition on your 3rd drive - we are trying to get it to mount fstab with this line

/dev/sdc5 /media/disc2 ext3 defaults 0 2

Clear as mud I'm sure.

Lets get the work done and then we can look at what we've done and try to get a bit of understanding - got all day and most of the night


Edit - you are running these commands ina terminal aren't you?

u see am quite new to linux myself but from the little i know ... Ur system seem to have seen the 3 other drives .. u just dont know it ..

u need to know that

In windows disk drives are assigned an alphabet letter, and traditionally - floppy disk drives were a: and / or b:, and the main hard drive was c:/. Then the first cdrom or dvdrom was d:/, and any additional drives would be e:, f:, and so on. In linux it’s kind of the same, but in a different format. All hard drives installed are listed in the ‘device’ or /dev directory. All drives start with the appendage “sd” i (think for storage drive)

So, if you have 2 hard drives and one cdrom - then you have 3 devices. You have a sda, sdb, and sdc. The number of partitions comes next. If your main hard drive is linux - and you have 3 partitions, then you’ll have a sda1, sd2, and sd5. The partition numbers aren’t in a logical order - sda5 is always the swap partition.

from what i can see

u have

Disk /dev/sda: 500.1 GB, 500107862016 bytes --your first drive

Disk /dev/sdb: 500.1 GB, 500107862016 bytes -- your second drive

Disk /dev/sdc: 500.1 GB, 500107862016 bytes --your third drive

[quote=forestpixie;5045833]Hi - you need to post the error messages you get so we can see them please, yea can be bewildering I know

OK, since rebooting for a second time, I can see the hard drive icons on my desktop.

When I tried copying a small file to one of them, I get the following error message.

Error opening file '/media/disc1/JMorris852.pdf': Permission denied

So it seems I can now see the drives, but they are listed in the "Permissions" tab, under "Properties" when I right click the ocons on the desktop as...

The permissions of "disk 1" could not be determined.

and

The permissions of "disk 2" could not be determined.

So something so far seems to have happened so we are probably half way there?
