SOLVED: Unable to write to secondary hard disk

[webheadjunky]

Hi there

Re-installed Kubuntu Karmic Koala from scratch after failed upgrade

Used Pysdm utility to automatically mount internal second hard disk and it automounts fine
However, I cannot write to this at all!

Have used sudo chown -R raaj /media/sdb3 which executed through all sub folders and files and
then I rebooted but still no change!

Any ideas??

Thanks in advance

Re: Unable to write to secondary hard disk

If the sudo chown command succeeded, then apparently root does have write access to the drive. What do permissions look like on the folders and files of the drive?

Hi there

Thanks for quick response

I am down as the owner

I wonder if there is something wrong in the way I am mounting it...I tried editing \etc\fstab\ and added an RW in column 4 to make sure it didn't mount read only but that hasn't worked

If you post a copy of fstab then maybe someone will be able to tell whether something is wrong with it or not.

Thanks
Hope this formats ok:

# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>

/dev/sdb3 /media/sdb3 ext3 errors=remount-ro,rw,users 0 0
/dev/sdb1 /media/sdb1 ext3 errors=remount-ro,rw,users,noauto,user 0 0

sdb3 and sdb1 are for the same hard disk
Unfortunately, I'm learning the ropes and I think I inadvertently managed to create two mount points for the one drive!!

Re: Unable to write to secondary hard disk

could you post the output of

sudo blkid

and

sudo fdisk -l

that's a lower case L not an I

Re: Unable to write to secondary hard disk

thats the strangest disk layout I'v ever seen and I personaley dont know how to straten it out.

is you'r hole kubuntu install on /dev/sda ?

and /dev/sdb just extra storage ?

or is /dev/sdb part of kubuntu?

as it apears in fstab it looks like /dev/sdb is just extra storage in /media!!

is so it should be safe to remove it all togeter from fstab and repartition it.... but all data will be lost so coey it off some ware safe first.

Re: Unable to write to secondary hard disk

Crap, what a mess. Sorry but I don't understand what you've got there.

I'll just say this. You don't mount drives. You mount filesystems. A file system exists on a partition. A partition exists on a drive. Generally speaking:

sda is a drive
sda1 is a partition which might contain a mountable filesystem.

Heh heh

What can I say...I'm a talented learner!!

Aye, the second disk is just storage

I was planning to backup and wipe and re-format to EXT4 so will do that anyway

Just in case I don't have permissions...is there a killer command that will let me reformat it to EXT4??

Thanks for all the advice

Re: SOLVED: Unable to write to secondary hard disk

I usualey do ALL my partitioning with a Gparted live cd.

it's never faled me.

Re: SOLVED: Unable to write to secondary hard disk

Yeah, in GParted Live CD session,
Device > Create partition table
and you'll have to set a disk label, MSDOS being the default (the standard PC MBR).

I don't think most of us are familiar with your Sun Disk Label or the notation /dev/sdb1p1 etc.

Re: SOLVED: Unable to write to secondary hard disk

I honestly can't remember how I did it last time!

It was over a year ago and via instructions posted on the Ubuntu forum

How do I create a Gparted live cd? I have the application installed but not sure how the live cd thing works

Thanks again

Re: SOLVED: Unable to write to secondary hard disk

GParted (Live CD, USB, HD)
http://gparted.sourceforge.net/livecd.php
New Manual. New man page. See Documentation:
http://gparted.sourceforge.net/documentation.php


You have to download the iso file and burn it as an image to a CD, using, say K3b, same as you'd do to make a Kubuntu Live CD.
