Hi,
I'm looking for a way to backup and wipe the ext-partition. I'm using ClockWordMod and partitioned my SD with ROM Manager.
ClockWorkMod can't mount my ext-Partition - so there is no way to wipe it or back it up.
With other Recoverymods Restore didn't work at all. So I'm perfectly happy with ClockWorkMod as it's reliable - the only problem is, that I can't do anything with the ext-Partition...
Any suggestions?
Linux can read ext partitions and backup/wipe no problem, but if your a Windows user then you will have to try a different recovery such as AM Desire Recovery, he says he has ext wipe working

i had the same problem then i flashed the permanent recovery (www.unrevoked.com/recovery) and problem solved!
Seems like ClockWork doesn't work with ext2 for me. Tried various versions, couldn't mount any ext2 partition (and that's what you get, when you partition your SD with ROM Manager).
I reformatted the partition to ext3 with Linux (I know there are also other Recoverys, but I find them too unreliable) and now everything works fine.
Strange that ClockWork can only mount ext3 but no ext2...
Of course this solves my original problem as I can wipe and backup the ext-partition with ClockWork now.
I have the same problem with my ext2 partition here.
If I run ext2 -> ext3 in Recovery, is my ext partition wiped after that? Or is anything running unchanged afterwards?

I tried this, partition didn't get wiped and I was able to do a nandroid incl ext after that.

Shouldn't get wiped, no.
ok well on my Amon Ra Recovery.
there is an option for nandroid back up and theres another
option about nandroid + ext backup.
i think thats it.
but i have no clue what nandroid +ext backup.
what does ext mean? extension?
whats the extension for?
and there other options are google proprietary files back and restore.
what the heck is that?
please some give me answers.
it is for people have an multiple partitions on their SD card. ext is a type of partition
The ext partition is a linux partition type used by Dark Tremor's a2sd. Basically, if your custom rom supports a2sd, you can extend your apps installation space by creating an ext 2 (can be upgraded to ext 3 and 4) partition on the sd card besides the normal fat32 partition. If you don't have an ext partition, just do a simple nandroid backup. Otherwise do nandroid + ext backup if you do have one.
Hi,
I searched various forums but cant find an answer to this.
Does cwm 3.0.0.5 backup and produce an sd-ext.img?
I recently got a replacement sd card, so I did a nandroid backup after I flashed cwm 3.0.0.5.
I copied this to my laptop, and g parted my new sd to have 2 partitions fat 32 first and the last 2 gb as ext3, as per the requirement for modaco no sense kitchen rom (a2sd+ version).
New sd in desire, I copied the whole clockworkmod folder onto the new fat32 partition.
Wiped everything I could using recovery (clockworkmod folder still remains present).
Tried to restore but got a message at the end that "sd-ext.img not found. Skipping restore of /sd-ext. Restore complete."
When I boot the desire gets past initial alpharev s-off replacement image I have (I have s-off), then presents a blank screen. This does eventually boot. However all apps are not installed. I assume that the original dalvik cache was not transferred and was reconstructed by the restore with what it had.
Is this a known problem with 3.0.0.5?
Is there another version I can flash which doesnt have this problem?
Just to provide all possible info require (I think). My desire is PVT4.
Thanks in advance.
I used CWM 2.5.0.7 from the alpharev release.
In my backup folder, I have sd-ext.img present.
I created this sd-ext with CWM itself. (I did a backup of the sd and formatted it)
So no doubt that CWM 3.0.0.5 did the same.
First, check if you actually have the sd-ext.img file.
Second, you might want to try to update to CWM 3, since the alpharev release is 2.5.1.8.
Well CWM will create the sd-ext.img backup if it detects that the partition is there. If out doesn't detect it then it will skip it like it did. There is nothing wrong with cwm at all and out works. You could upgrade your recovery to 3.2.0.1 but it won't make a difference really. Only way around it is to use titanium backup as it will restore straight to sd-ext

Hi,
I used gparted to firstly create a fat 32 partition then secondly a ext3 partition (for apps) on a new sd card. I cant see a sd-ext.img file in the nandroid backup file produced by cwm 3.0.0.5 so I assume that it cannot detect the ext3 partition.
Do you have any idea as to why this is? Can I have done anything to help cwm "see" the partition.
I'll update to 3.2.0.1 to try if the same problem occurs in that release.
I take your point that I could use titanium backup to achieve the same. I dont really want to do this as as I find it a pain to re-install the large number of apps I like to carry about on my desire. The problem is that I know what runs well on a ext-3 partition and what only runs on int or system space. I only allow apps into system or int if I really them to be there so this means thatyou have to manually install each one of them to the relevant space. Also I use ext3 for dalvik cache (seems to improve performance).
I cant see a reason why 3.0.0.5 didnt see the ext3 partition and ideally I would like a nandroid recovery solution that could auto detect all partitions if present (as I guess many others would).
I'll update this thread when I have run through the update to 3.2.0.1 and done some more testing.
I think CWM doesn't backup ext-partition if there's no data
try the old CWM.. the one comes while you root with unrevoked3 .. coz I have old CWM and it does backup sd-ext.
I created the SDCard partitions using ClockWorkMod v5.0.2.0, now when I try to take a Nandroid backup,it works through all the partitions, until sd-ext and gives the following error :
"Could not mount sd-ext. sd-ext backup may not be supported on this device. Skipping backup of sd-ext" followed by the usual "Generating md5 sum..."

I have a 512 MB Ext .Phone recognizes the sd-ext without any problem. I have mounted and configured it using S2E.
WTH is going wrong ?Any ideas ?
Thanks

S2E here, too - how did you partition the card - CWM? (I'd guess usually that shouldn't lead into problems...)
Did you also mount the partition manually in CWM? (I'm pretty sure that I didn't - but that's still an open question / if I have to / should) - what CWM version?

Yep,obviously,I used CWM 5.0.2.0 for the partition of the card.
I am using CWM 5.0.2.0 for the Nandroid backup and I have also tried via ROM manager to no avail.
SD-Ext is already mounted
Hbu?Have you achieved the Nandroid backup(including ext) without any problem ?What CWM did you use ?
I just don't understand why CWM can't back it up when it was created by itslef.
Does CWM 5.0.2.0 supports ext3/4 ?
I am pretty sure I created ext3 partiton using it and now when I mount my SD card via ADB,it shows the file system as ext2

Have you made nandroid with cwm 5.0.2.0 ?
Yep
Then surely it looks some issue with your SD-ext,I would recommend you to repartition using minitool partition wizard,For now you could use app extractor app to restore your apps/data from nandroid.
you can try cwm 5.0.2.8 (the latest available) this is the link of the tread
http://forum.xda-developers.com/showthread.php?t=1566677
I know that the recovery have some problems creating / formatting partitions ext (eg creates ext4 but reformat in ext3 when you wipe), then I suggest GParted utility on the ubuntu live cd to partition the microsd.

BTW,I have already backed up my applications using TB and the app data should be in internal memory as it was not moved to ext.
I just want to have the recovery fixed to backup.
You can't just copy the whole SD card on the PC as it can't read the sdext# directory.
Most of the people recommend CWM for the partiton of the card and they didn't have any problem with that.Which recovery did you use ?
Doh! I am clueless
tb save the app to a folder on fat32 (microsd) You must backup this partition before reformatting the entire micro sd or use gparted to erase/formatting only the ext partition

I prefer FASTBOOT
I had been using cwm 5.0.2.8 for a long time with no issues while backing up and restoring nandroid including sd-ext.
But due to mirroring bug in temporary 2.5.0.7 with 5.0.2.8,i downgraded to v5.0.2.0.
From then I started to have problems in restoring nandroids made previously with v5.0.2.8.I did everything again(partitioning,backup and restore) with 5.0.2.0,and it all started to work as before again.
So,I jumped to a conclusion that if you create sd-ext with specific cwm version then you should use the same version to backup or restore nandroids.
I know this sounds silly but proved to be good in my case.I might be wrong though.

my experience with cwm 5.0.2.8 I restore old backups made with 4.0.1.4 without any problems and found it very useful for advanced restore
Flashed recovery 5.0.2.8,now when i try to backup(nandroid) it goes like this :
Backing up boot image...
Backing up recovery image...
Backing up system...

Nothing happens after that(waited for 30 mints) and when i try to reboot the device it gets stuck on htc logo for few mints and then boot into recovery.
Doh!Seriously,I am fed up with this ****.

I'm using 4.0.1.4 - by accident because of that wrong PC49IMG file in the index thread and I'm really too lazy to update.
Re. your problems: There are a few reports that CWM (all versions) sometimes fails with wiping/formatting (or does it a bit dirty) so I'd guess this very likely could also happen with partitioning (if I'm correct the partitions will be wiped and formatted also, then). I really would just repartition again - and afterwards I'd do a complete wipe/format of the sd-ext - just to make sure...
Keep in mind that a sdcard is not a hard drive...
Hello, first calm down, you have just installed a recovery
second probably the trouble (as you have already said) is the card, the formatting you? if you do not want to lose the data on your ext partition with gparted can copy them like a fat partition
even if given the situation I suggest you start from scratch. deep Formatting
partition with ubuntu live cd and flash the rom (I understand that will not boot up right? The ext partition is recognized as the first boot). There is a possibility that the micro sd does not work well anyway good luck I hope I can help you

Cosmicdan has been recommending to use TWRP with his kernel. What I want to know is if TWRP backs up the vendor partition. The last time I did a cwm backup and then restored after some issues, i ended up losing a lot of apps because the vendor partition is not backed up by cwm. I was using 5.0.2.7.
So no one knows if TWRP backup does the vendor partition?
