Hello- I just installed Kubuntu - Hardy Heron last night. Previously I had my computer dual booted with Ubuntu Dapper on my 80 gig HD and Windoze XP on the other, 20 gig HD. Last night I decided to do away with my windoze partition altogether because I never use it (besides I have a mac laptop anyway) but I did not know how to manually set the partitions so I just installed Kubuntu on the 80 gig one. The 20 gig mounts as /media/hdb1 and has a bunch of my old windows files on it. I would like to reformat this HD to be a logical drive - extension of my Kubuntu, but again, don't know how to do that.

Will gparted do this reliably in Kubuntu? Or, how do I do this with the command line? I have been trying to RTFM but am not having much luck deciphering what I am reading. Any help is greatly appreciated. THANK YOU!

Apparently all you want is to "format that partition"

#sudo mkfs.jfs /dev/hdb1

DONE
----------------------

Otherwise,

Install gparted or parted

#sudo parted /dev/hdb
> p

you will see the list of partitions

Why do you want hdb1 to be logical (within an extended)?
You can make up to 4 primaries on each drive... actually you cannot turn a primary into logical within extended without destroying all the data on the drive.


>mkfs is your command (see help)

On gparted it is on a GUI

of course you must edit /etc/fstab after that

#/dev/hdb1
<remove line below this>

<replace with>
/dev/hdb1 <tab> /media/hdb1 <tab>jfs <tab>...

Thank you very much, but all is not well!

I had to install mkfs first, before I was able to sudo mkfs.jfs /dev/sdb1. (Oh yeah, it's sdb1, not hdb1. I could have sworn it did say hdb1 before though...)

Successfully erased all data on that drive. Then typed in kdesu kate /etc/fstab to edit /etc/fstab.

All I saw was

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/sda1
UUID=87d51a87-cb1d-4af3-bc1c-debf3cb52ca4 / ext3 relatime,errors=remount-ro 0 1
# /dev/sda5
UUID=c73118ea-7d81-4b88-8a98-45a44639e1e5 none swap sw 0 0
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/scd1 /media/cdrom1 udf,iso9660 user,noauto,exec,utf8 0 0
/dev/fd0 /media/floppy0 auto rw,user,noauto,exec,utf8 0 0


So I then added these two lines:
# /dev/sdb1
/dev/sdb1 /media/sdb1 jfs

But after that, when I would go to mount the drive it just said "access denied".

I tried chmod a+rwx /media/sdb1 thinking that should change permissions but it did not do any good.

Then I tried qtparted, but it doesn't do anything. It looks like it's loading, but then nothing happens.

Then I downloaded gparted (it works- yay!) and tried to reformat the drive that way - but now the drive does not even show up in konqueror!

OK - I found a tutorial here: http://www.psychocats.net/ubuntu/mountlinux

about mounting linux partitions in Ubuntu. I followed those instructions and now that other drive just looks like another folder. Since I just wanted to clear out all the Windows junk and be able to have that space available for Linux files, I guess this will work. Anyways, thanks for the help. Gparted worked great.

You should add the line

/dev/sdb1 /media/sdb1 jfs defaults 0 2

in /etc/fstab

I had kept it open for other options

Oh I C. :-) Well that's ok. Since I'm still learning I will just file this info into my personal how-to manual for later reference. Thanks again!
