Is that some kind of partition? What's the deal? Why use it?
Also, is there a way to detect "loss" (undetectable) EXT?
They are just Linux partitions. I'm no chef but I believe apps2sd is simply a hack to get Android to read the file systems.
AFAIK you can't detect a "lost" partition through Android as it us only configured to read FAT.

Can anyone make a tutorial that shows how to partition SD card for the Android Eclair for Kaiser -- Dark Themed ? Please, greatly appricated if you did =]
Moved as not ROM Development.
Think your best bet is to PM one of the peeps releasing builds to ask if they can? or ask in one of the numerous droid threads.
I suggest using Gparted.
As I understand, Android can read ext2, which is light years ahead of fat32.
Warning: The following assumes that Andriod's file system and base operation operates like GNU/Linux
I'm not sure this will work... or how to get android to do this... but:
In GNU/linux, you would make a line in /etc/fstab for the device, unless it is handled by an automounter they designed.
Anyway, you can resize the fat32 to two partitions, and you should be able to make a 2ndary partition on the SD for linux.
I assume you are running windows, so to run Gparted, you will need to use the Live CD.
http://gparted.sourceforge.net/download.php
A sample fstab line:
Code:
# <file system> <mount point> <type> <options> <dump> <pass>
UUID=7d126676-b613-457f-b50f-5f69929b06d6 / ext3 errors=remount-ro 0 1
/dev/sda6 /home ext4 errors=remount-ro 0 1
I'd assume they have some sort of andriod application that opens a terminal with bash, or edit the /etc/fstab by some other means.
Best of luck!
Or you can just do this in Fat32

Thanks for the attempt at an explanation. I'm in the same boat as the original poster. I think the problem is that Android is currently running from my SD card on my Tilt, so I don't know if it's possible to partition the card while Android is running.
I've got a Windows 7 PC at home, and I can boot it from a Linux CD if needed... but I'm a total Linux NEWB. I'd really appreciate it if someone can point me to instructions for how to partition a 4 GB SD card to accommodate an Androd build along with being accessible form Windows Mobile.
Can someone give an overview of the process and maybe some partition size guidelines?
Thanks,

Gparted is good, it lets you resize partitions without formating them. It's part of the Ubuntu live cd's.

i repartitioned my sd card with a 64mb swap,2gb ext2 and the rest fat32 using ra recovery. im running cyanogen 4.2.13. when i type 'free' into terminal it says 0 for total,used, and free. am i missing something? or do i need to "activate" the swap partition? TY
here you go
forum.xda-developers.com/showthread.php?t=542899
remember search is your friend
i came across this great site about swapping: http://wiki.cyanogenmod.com/index.php/Compcache
im wondering what other options others on this forum use and which one is the most recommended?
compcache
swap
or
backing swap
ty
backing swap seems to be the way togo, but i would like a professional opinion.
2GB its too much for an EXT partition.....i have seen (somewhere) that the recomended size its 512mb...not sure tought...
About the Swap...idk, but i like Compcache...some devs (like WG) says that their roms runs better without Swap.
EDIT:
Here is what i was talking about the EXT partition.
This was on [Guide] Partition your Sd Card, Upgrade to Ext3, and Install Apps2SD.

Partition Fat32/Ext2 with App2SD
Open up Apps2SD
It will show you a screen telling you that your card is not partition and you will have a sliding bar to choose the amount of space you want for an EXT2 partition
I suggest a max of 600mb for EXT2 space (I use 500mb)
Press Ok
You will get a Force Close screen DONT PRESS FORCE CLOSE PRESS WAIT
You will get a reboot message, Press Reboot
You now have a EXT2 partition

is there a specific reason to not have a large ext2 partition? i wanted to have plenty of room for both apps2sd and installing debian. im using this guide:
http://all-google-android.com/googl...verdale's-debian-boot-v-2-0-updated-03092009/
the thing i like about this one:
" this will run a full Linux distribution (Debian) on the Linux partition of your sdcard (EXT2/3/4). I have written the script to bind Debian folders to your regular folders, and thus give you access to the entire system while running Debian"
I only have FAT 32 and linux swap. I just notices that I can't mount /system/sd. If this is because I have no EXT, is there still a way to run switchrom?

perhaps this would answer your question, i was having a similar problem, have yet to test the updated switchrom, will update back here once i have tested it

can someone explain this to me....how does this works?
What do you want to know, they are different file systems...thats about it.
Only OC roms ahve support for ext4.
what exactly do they do?

They are filesystems. You partition your SD card to have one so that ROMs that utilize apps2sd will place your Apps into that partition on your hard drive.
ext2 is an open source alternative to fat16/32
ext3 introduced journaling to ext2
ext4 introduced many performance enhancements and better reliability.
That is a very simple explanation and the differences between the versions are very technical.

you need to have rooted your phone and loaded a custom recovery. Then reboot into recover and partition the SD card with a ext2. In the partition screen update your newly ext2 partition to ext3(I would not go to ext4 unless you really know what you are doing).
If your custom ROM supports it then the apps will be stored on the SD. You need to check with the ROM you load. Most ROMs support it but you need to double check.
I'm wondering if it's possible to create an ext3/4 partition on the SD-card and use it for files over 4gb. The main reason I want this is to play with Backtrack 5 for the ARM architecture. I'm guessing it should be as simple as partitioning my SD-card w/ a Fat32 partition as the first partition and then ext3/4 as my second and then adding a mount option into the fstab file. Just wanted to run it by anyone else that has already done it, or knows a better way.
PS. In case anyone else is interested, here's a thread with partial instructions on install Backtrack (if you're familiar with Linux, figuring out the rest shouldn't be difficult): http://forum.xda-developers.com/showthread.php?t=1074723&highlight=backtrack
Edit: Just found this: http://denniskuntz.com/blog/2011/05/11/backtrack-5-on-the-nook-color/ So, it seems it's possible. But, still have the question of can you have both a FAT32 and a ext2/3/4 partition on there and keep your nook functional as normal, but have a separate partition to run BT5 off of?
