Nandroid sees no sd-ext ? - Desire Q&A, Help & Troubleshooting

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

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

[Q] A2SD+ mounting sdcard in windows

right so i have now formated my sdcard with an ext4 partition and a fat32 and it works quite well but i cant seem to mount the sdcard in windows so i can transfer files over to the fat32 partition, it works tho in linux on my laptop so what am i doing wrong :| ?
Did u format it by yourself ? I used ROM manager to create ext3 partitions and no problem with windows, it just doesn't see ext partitions which is normal.
Is your FAT32 partition the first partition on your SD card, or did you create the EXT partition first?
Regards,
Dave
fat is first but it seems after a phone reboot it works in windows again :S

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.

See mine..
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] Deleting a partition on the SD card.

How do I remove a hidden partition that I created with ROM Manager
Thanks.
it depends what OS ur using, if ur in any Linux variant id use Gparted
if in MS windows i think u can do it by
click 'START'
then right mouse 'MY COMPUTER'
and left click on 'Manage'
then click 'Disk Management'
from there u might be able to see the Ext3 or Ext4 partition, to delete and resize the FAT partition.
If not just download a LiveCD eg Ubuntu and use Gparted off the LiveCD
Thank you for the reply, I sorted my problem and didn't need to delete the partition.
Much appreciated mate.

[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 ^_^

Actually partitioning to EXT under windows cause only problems.
Use gParted or recovery from my signature.

Just read forums more often, you'll find numerous people having a bootloop after partitioning under windows.

Links2SD with Linux

Hey,
I am using Linux as my primary OS (Arch Linux). I don't have Links2SD installed at the moment, but I'm thinking of installing it. Since I use Linux as my OS anyway, is it necessary to have a FAT partition? Can I just format the whole sdcard to ext3 or ext4?

Why would you format whole memory card as Ext4? BTW Link2sd won't work well if you have partition of more than 2 GB.

So that I will have The whole of my sdcard as internal memory. I basically don't need FAT/NTFS because I don't use Windows. My OS (Arch Linux) can read ext* filesystems too. In fact, all drives on my PC are ext4.

the only problem that I could imagine is that link2sd expects the ext-partition to be the second on the sd-card. but I don't know how link2sd works. I did it manually and just linked /data/app and /data/dalvik-cache to the ext-partition on the sd-card. another good reason to use 2 partitions might be the fact - if I'm not completely wrong - that the first partition is unmounted if you connect it to the pc and activate file transfer mode. if you linked whole /data to this first partition you might run into problems.
You'll still need a fat partition. Or at least two partitions, one for files and one for link2sd.

You mean if I put music in my Link2sd partition, it wont be playable?
Android and ext4
I'm not sure Android can read music files on ext4.
