Question: How to partition memory card (Ext2/Fat)? - maemo.org

BrentDC | # 1 | 2008-08-04, 23:37 | Report

I've searched everywhere for an answer to this seemingly easy question, but have come up empty.

I have an 8GB SD Card, and want to make two partitions on it: a 3GB Ext2, and a 5GB FAT. How can I do that on the device itself? (I don't have a computer with Linux on it...).

Any insight would be greatly appreciated.

Two options... sfdisk (hard) or cfdisk (easy)

cfdisk doesn't look to well in the default terminal... but ig you have decent eyesight u can go into the properties on the terminal and shrink the font size to 10-12 and it works great. Assuming /dev/mmcblk0 is the device:

Code:

cfdisk /dev/mmcblk0

once u made your two partitions:

Code:

mke2fs /dev/mmcblk0p1
mkfs.vfat /dev/mmcblk0p2

U can get cfdisk from here:

You might be able to use Disk Management on an xp machine (I haven't looked into this, but I use DM to delete partitions).

Go to Run, then enter "compmgmt.msc", then choose Disk Management

No, Disk Management is for Microsoft file systems.

@BrentDC

When you are partitioning, place the FAT partition as the first partition and the ext2 as the second partition.

Ok, I will try this today. Thanks, everybody. Oh, and is /dev/mmcblk1 the external memory card? (I'm booting from the internal memory card).

Yes, /dev/mmcblk1 is the external.

You can check by running "df -h" and seeing the mountpoint of /dev/mmcblk1
/media/mmc2 is where internal cards are mounted, and /media/mmc1 is where external cards are mounted.

I installed cfdisk, and after a few hours (

), I figured out how to use cfdisk. I created a 5Gig Windows partition, and a ~3Gig Linux partition. All my files seem to still be intact (on the fat partition?), but how do you access the other patition; I hope a Linux filesystem was the right choice with cfdisk. The External memory card now appears in bootmenu, which seems like a good sign, but how do I access the Linux (ext2?) partition?

did u run the mke2fs command?

if so as root
mkdir /media/linux
mount /dev/mmcblk1p2 /media/linux

if u want to make it start at boot the u have to edit /etc/fstab... the line would look something like

/dev/mmcblk1p2 /media/linux ext2 defaults 0 0

there are several options u could add but u'd have to look them up.

That worked perfectly. What I was trying to do was mount it on /media/mmc3/ , but an mmc3 folder didn't exist. It makes sense that you need to mount it on a real folder not thin air! I don't know what I was thinking

Thanks for the help.

Ooh, goody, 3GB of ext2 playpen, Debian here I come

Hello,
I am just joining this conversation (if it's still even being checked!) and the link to cfdisk doesn't exist anymore. I was wondering where to download it so I can make two partitions on my card!
