I'm afraid i am a relative newb to the nix world, although having been a unix user at uni and at home i haven't done all that other than be an end user.

My linux distrubtion, being Fedora, is installed on a second hdd, XP being on my primary, and this linux disc is at ten gigs, plus my swap space etc, but i want to partition the rest of it so i can use it, atm its just dormant. I've only ever used disk-druid on install or PM in windows, so atm i'm at a loss, as i've done some googleing and it looks as though i can't run disk druid outside of anaconda, and guessing i need to use fdisc but i'm a little scared that i'll end up destroying any of my partitons. I can't seem to find much help on the net, or that i can understand in the least, so hoping you guys could help me out a bit.

Cheers guys

Fdisk is pretty easy to use. And the changes don't take place until you write the table, so if you think you messed up or you want to stop, you can quit without losing everything. Also, check out cfdisk, which is a little easier to use.

cfdisk is not on fedora @ default

Do

fdisk -l

You can see partitions of my server (for the geeks yes partitions could be MUCH better but he! its a P2 my own temp fileserver at home)

Sort out wich partition it is about and use fdisk :

fdisk /dev/hda

The number of cylinders for this disk is set to 9729.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

all you need to know that there can be 4 primary partitions the fourth must be an extendend (can be primary 4 btw but that is stupid)

you make the partition and give it 83 Linux in the L list (default btw)

then write (w)

after that you can do mkfs.ext3 /dev/hda3 (for partition 3 on master ide drive on first ide interface)

now you can put him in /etc/fstab and mount the sucker
NOTE when you use label in fstab use e2label to label the disk but is basicly for higher purposes)

fdisk is simpel and great dont use easy tools learn the core with youre unix background you should know this also

use : man fdisk

hope it helps

dude thats stunning, thats exactly what i'm after, i'm doin a lotta learning here, forgotten how such a small thing can be such an accomplishment, heres what i got:

but how do i tell it to be a fat partition, when i made the partition should i have typed b for W95 FAT ??

thanks again

okay i'm one better, but i dont get how to format it,

/dev/hdb3 27048 155061 64519056 b W95 FAT32

i take it that mkfs is make file system, i worked that out, but how do i go about it, would it be

mkfs /dev/hdb3

i dont understand the .ext3, isn't that a type of format? so would i want .fat or am i way off?

You just need to use the commands. Press m to see them all. First, delete the partition you wish to get rid of. Then, create a new partition. It will default to Linux. Then use the 'w' command to write the table and quit. To create a file system, you can use a number of tools. Use 'makefs' for ext2 and ext3 filesystems, and 'mkreiserfs' for reiserfs filesystems.

i got the fdisking down ok, i just can't seem to sort out how to format it to fat, i'm getting a bit tired, may leave it for the morning

What filesystem do you want to use? You might want to put a bit of research into Linux filesystems. The most common filesystem is probably ext3. I personally use reiserfs.

i actually want it to be Fat32, and have worked out how to do it,but i'm getting a error that i dont understand:

firstly, i've made hdb3 in fdisk to be fat according to the partition table:

Disk /dev/hdb: 80.0 GB, 80026361856 bytes
16 heads, 63 sectors/track, 155061 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

/dev/hdb3 27048 155061 64519056 c W95 FAT32 (LBA)


so its there, hdb3.

i'm now using mkfs.vfat or mkfs -t vfat:

root@localhost puk]# /sbin/mkfs.vfat /dev/hdb3
mkfs.vfat 2.8 (28 Feb 2001)
/dev/hdb3: No such device or address

and

[root@localhost puk]# /sbin/mkfs -t vfat /dev/hdb3
mkfs.vfat 2.8 (28 Feb 2001)
/dev/hdb3: No such device or address


it can't find the device but it is there as i proved with the above table, am i missing something here?

cheers

Some versions of Linux require a reboot after creating new partitions.
