Nandroid sees no sd-ext ?

I run nandroid with a new partitioned SD-card.
I partitioned the SD-Card under Windows to 28GB FAT32 and 2 GB Ext-2
The backup process nevertheless says
"E:can't mount /dev/block/mmcblk0p2 (file exists)
could not mount sd-ext. sd-ext backup may not be supported on this device"
any ideas?

It has to be EXT3. Not EXT2. I'd use the phone to create the partition then upgrade it to EXT3.
On a side note, I didn't know Windows could create an EXT partition as it's a Linux file system.

The same way that Linux supports Windows file systems like NTFS - additional drivers!

Excellent, thanks for that Dave. You never stop learning in here

Forgive my noobness but what advantage does having the ext3 partition have? Is it required?
Thanks

Then I just setup my SD card with ACRONIS TRUE IMAGE 2010. It let'S you install a new HDD with various file formats

How to create ext3 partition on SD-Card under Windows

This post is for people scared of Linux (like me)
I finally found a way to partition a SD-Card under Windows. I tried more tools, but only one was able to work with SD-Cards. Here's what you need to do:
1. Download and install MiniTool Partition Wizard (google it, i cant post links)
2. Resize original FAT32 partition to make room for the ext3 one. If you have enough space, the data on the card shouldn't be affected, but make a back-up just in case.
3. Create the ext3 partition on the space made available and apply changes
The first partition should be FAT32, and the second ext3, make sure you have them in this order.

Almost all custom partition managers can do this in Windows-Partition Magic, Paragon, Or Gparted with VMWare

They can, but not on SD Card. Windows doesn't support partitions on memory cards. I tried Partition Magic, Paragon, Easeus, none of them work.
I didn't try Gparted with VMWare tho, you might be right about that.

Paragon works for me on Windows..And Gparted is what I use

Strange, it didn't work for me (see attached pics).

Just install the latest ClockworkMod, or Amon-RA and do it through recovery.

Is it useful to have an ext3 partition on SD card with stock 2.2 rom ?

It's useless, you need a ROM that supports it.

quick question - if I create an ext3 partition using this method or any other way, and then move the apps I had on SD (the old way) back to internal, will it then move them to the ext3 partition automatically? I just want to make sure I have this right myself before I attempt it.
I'm using Oxygen 2.3 ROM RC-6 which supports apps2sd etc.
thanks in advance for any replies.

I'm using 9.0 Pro, you're using 10.0 server, if that helps..
I still prefer Gparted though..On Vmware.

The a2sd+ script is built in, it executes at installation. Best way would be to use Titanium to backup ur froyo a2sd apps, wipe+install a2sd+ custom rom, use the option of Titanium, to move to sd.

and how do you want to put data on the ext3 partition ? ... you will need linux, its the best way...

partition works, but..
i tried minitool and easueus, both partiotion my 16 gb sd card, but...
I use miui rom, xpart(data2ext). the script works, but the phone is slow as ........
someone any idea?
i also have a 8 gb card, same partitions, but no problem..
any idea how i can tets my 16 gb card?

Minitool is crap. Haven't used easeus but its still under Windows, which is a no no
Gparted is the only decent tool that will nicely partition an ext partition on your sd whilst aligning it properly. This is both my personal and professional opinion.
Now because it doesn't run in windows, its a bit more long winded but so much more worth while.
Virtual machine (vmware player) is the best method. There is a link to a guide to set this up in my signature

[Q] Repartitioning

I've already partitioned my SD Card with Fat 32 and 512mb Ext 3.
The problem I have now is some of the ROM's I like suggest having a 1gb Ext3 or 4 partition. How easy is it to repartition? How do I back up what's on the Ext 3 partition (I'm guessing though that I can't without a Linux OS on my PC)?

in order to repartition you would have to use some other recovery (AmonRA or newer clockworkmod perhaps) that has the option to make 1GB ext partition.
regarding backup - NANDROID backups SD-EXT, and every recovery has an option of restoring some partos of bacup only (like only sd-ext but i think you dont need that since you want to change ROM) other option is to use a linux os, dont worry you dont have to install it on PC, generally you can run linux from a CD and make changes on EXT as you wish (again i dont know what would you like to do there)
if you dont want to / cant update recovery, download program Gparted LiveCD, and burn it to a CD. it will be bootable, boot it on your PC, then plug phone while in recovery with USB Mass storage enabled, choose the SD card in gparted, and expand your 512mb ext to 1gb ext3/4 partiton (still after the FAT32)

http://www.partitionwizard.com/download.html I'd reccommend using a partition tool from your PC, more reliable in my opinion ^_^

[Q] ext4 What is it?!

I have been using a custom ROM for a while now and I have been seeing in the thread that many people are using ext4.
I have asked many times in the thread and recieved no reply.
So my question to you is what is "ext4" and what bennifit will it be to me as a Desire owner.
Thanks

1. Google is your friend
EXT4 is a file format used by Linux (Android = Linux). When threads talk about EXT4, they are referring to creating an EXT4 partition on your SD-Card e.g. have 14GB FAT32 and 1GB EXT4 (from 16GB SD-Card.. 1GB is always non-existent)
What having an EXT4 partition enables you to do, is to have Apps/Data2EXT scripts which move apps to the EXT partition, giving you a lot more internal space.

Moving some of the app data to the sd-card is different to having an EXT partition and A2SD.
If you activate A2SD, the system will install and store your apps on the EXT partition, and your internal memory will not be filled up, and will remain at xxxMB. Furthermore, with an EXT partition you can use D2EXT, which makes your phone use the EXT partition as the data partition, so if you have 1GB EXT4, your phone will see 1GB memory.
If you use the inbuilt "move to sdcard" function, it only moves some of the sd-card to the android-secure folder on your sd-card, however your internal memory is still used up.

In addition, moving apps to sd-ext partition doesn't break app widgets like the stock app2sd method that Gingerbread use.

Reason: With A2SD / DATA2SD / etc. Android still "thinks and tells" the Apps are still installed in the internal memory (at least this tells me my logic).

if it's MW based on oxygen, instructions on how to enable ext4 partition are in the first post, no need to use an app.

backup your sd card 1st
then use only 4ext recovery (requires s-off to change recovery) or gparted to create your partition (step 5 here)

EXT4 SD card partition not appearing or working

Hi,
I have upgraded from 2.3.7 to a JB MOD. I prepared my SD card in gparted with a 500mb FAT32 and the rest as EXT4. I have inserted the SD card and 'setting\storage' only sees the in built 150MB EXT and the 500MB FAT32 on the SD Card but no 3GB EXT4 partition. In terminal I ran a2sd install and on the reboot it said 'optimising' apps and I thought it was moving apps. However, when I install apps from the store they are installed on the in built RAM.
Using app2sd I can't move any apps I used to be able to on 2.3.7.
Can someone please advise?
Thanks
Paul

Here is your most likely scenario because it happened to me: If you created your partition on a PC, for some reason it doesn't work properly (well at least in my case). Then the phone doesn't read the SD card properly. What you should do is upgrade clockswork mod recovery on your phone to the most recent version and create the EXT version using the recovery console by booting into recovery.

Thanks

it should be 500mb ext4 and the rest fat 32, also 1gb ext4 is recommended and dont use ClockWorkMod recovery to partition sdcard, use 4ext recovery instead. CWM makes bad partitions

I've redone my card (3GB FAT32/500MB EXT4) but my in built memory seems to run out of space for apps quickly. I thought the SD-Card EXT4 partition was supposed to add more space for apps to the phone.
Is this not true?

Hi,
I am using Elk759 JB ROM. I did run the a2sd in terminal after redoing the partitions. It reboots and says optimising apps 1/...79 (whatever number). I can't tell if it has moved anything onto the EXT4 partition of my SD card.
I will boot into a live linux and take a look on that partition.
If it isn't working is there anything I can do?
Thanks

That seems to have worked as I've installed loads of apps and it hasn't complained about space.
Thanks for all your help.
