Basically, every time I go to clockwork recovery and try to wipe data and cache, I get this error.
cant mount block /dev/block/mmcblk0
I have reformatted many times my sd, even with rom manager but with no luck.
Still get the same error.
From what I understand, if I flash a rom that supports aps2sd+ then I cant install any apps from market because it cannot mount my sd card.
You probably have an ext2 partition which clockwork can't handle. I had to convert mine to ext3 to be able to format it in recovery. Apps were still being saved there, though.

I had this problem while my ext was ext4. I had a ROM that was OK using ext4 but clockwork wouldn't back it up, so I reformated SD with ext3.

After I read through several hundred pages on different topics but all treating the sd-ext one or the other way, I still think, that my problem has another twist.
I recently rooted my phone and I'm running Leedroid 3.0.8.2 APSD with S-On. Now everything runs perfectly: quick system info shows my apsd partition, apps are saved there (also new ones I installed after flashing the rom), titanium backups them and my phone runs smoothly.
But, clockworkmod cannot mount the sd-ext, cannot backup it nor restore it. And root explorer cannot find it.
I tried to format the sd card and remaking the partitions. I tried all other solutions I found on xda, but the problem remains.
Can anyone help?

hi,
seems that your problem is your CWM version, already read a problem's like this.. buggy recovery.
look into devlopment thread recovery cwm, think this issue is related there.
depends the version u got
http://forum.xda-developers.com/showthread.php?t=1112658
be aware that to flash new recovery, best way is to be s-off
hope this help
How did you format it? With Linux or the Rommanager,...? Is this problem new?
Maybe you have to flash a new version of the Clockworkmod. Therefore you would have to S-off the device.
Please give us more information.
I made the partions using MiniTool Partition Wizard on Windows. I have cwm 2.5.0.7. But the first time I made the partitions I used the rommanager.
The thing is, that the root explorer doesn't recognize the sd-ext either. I will try to flash a new recovery though. Can't I use unrevoked for this too?
The format of the sd-ext partition is ext3.

After the first partitioning, I zipalingned the sd-ext using the recommended tool by Leedroid. But after that I was stuck on the splash screen, so I remade the partitions using MiniTool.
Then I was able to flash the rom and get my phone going again, but had the problem with sd-ext.
A week later, I wiped the sdcard anew and tried again, but the problem persisted.

I had a similar problem. I solved it by flashing the alignment patch twice (first time: splash screen freeze, second time: bootup and mountable in recovery)
Goodluck

Please try to format the card with linux, the rommanager or the cwm. It is only possible to flash another recovery when you are s-off as far as I know.
You can also backup the data with linux. Copy the files to the card back and restore the ext in the recovery otherwise it won't work. I would also backup the apps with TB before just to be on the safe site.

Hi don 't use alignment zip iit was design for typical rom (data2ext ) 'use instead gpartes but since your rom with a2sd or whtever with ext boot means that U got a working ext fs... To see what is stored in ext use quick system info or browse to system/sd directory.

Hello!
I think, your ext is working well. If its not working, you should not be able to use the Rom as you described. As written by other user, look with root explorer into the directory /system/sd. Here you see the content of the ext-partition. You won't see a folder like /sd-ext in a file explorer. On a running phone the Fat32 partition of sd-card is accessable as /sdcard, the ext-partition as /system/sd .
After you mount your sd-ext in recovery, look into the mounts section, there you should see a line called unmount sd-ext - if you see this, the ext-partition should be successfully mounted. In recovery with mounted sd-ext you should be able to access ext-partition with adb, mounted as /sd-ext
Hope what I have written makes sense

Ah, I always thought that I should look for a folder called sd-ext. I know think that the problem lies with the cwm and the fact that v2.5.0.7 doesn't recognize my sd-ext partition, probably because it is ext3. The sd-ext partition isn't and cannot be mounted in recovery.
You think flashing a new recovery could help? And if yes, what is the best way to flash it when s-on?
Thanks!

I would try to format the card again (with linux or the rommanager, cwm).
You have to be S-Off to flash a new recovery as I told you before.
Therefore I would first try to format the sd card again (not with windows).
http://forum.xda-developers.com/showthread.php?t=1112658 if you want to flash a new version (You would have to s-off the device. It could be that you have to install a ruu and reroot the device for that procedure, because alpharev is not able to install the hboot with every rom)

I Use the same recovery like u. No problems with ext-partition (ext3) here. I don't believe its your recovery, I think its your sd-card or partition. Download gparted boot cd, burn it to cd, boot it. Delete at first all partitions on the sd-card, kick apply! Then build new partitions. There are a lot videos in YouTube about using gparted if necessary.

I tried using CWM to do the partitions, but couldn't find the command. Either way, I think I leave it at that, at least until the next update of Leedroid, as the Rom, TB and everything else works perfectly.
If any of you has another idea... Btw, does it matter which class of sdcard one has?
Thanks!

Gparted is good to use... No class shouldn't make a difference for partitioning on speed of data transfer etc

Solved
Finally solved my problem! I s-offed my desire and flashed AmonRa, did the sd-ext repair and got it going! thanks all of you for your support!
i formatted my sdcard then i made and sd-ext partition trough cwm 5.0.2.6
and s2e cant seem to find it.
cwm creates a corrupted ext-sd partition, if you are on windows use the minitool partition wizard, or if you're in linux, and already have the corrupted partition use gparted to fix the errors, or create the partition again.
Had told you already.
Dont create the same threads when it is answered

Px is based on CWM. Do U use CM9?
no...cm7.2
Well, everytime cwm formated the ext4 ext-sd it was corrupted for me... And I used gparted to fix it... When I used minitool to create the partition it also worked well.... Did you activate the ext4 setting in s2e?
Install a SD card/disk tool, s2e uses FreeSpace. It will display if your partion is well formatted or not. Also you can try mounting sd-ext in recovery, if it doesn't mount, it's corrupted. But the best solution is of course using Partition Mini.
I am trying to enable the option to move data to sd-ext on my ARC S , but it is not working , tried the reverse mount and it doesn't work either.
It only allows my to move the application , and i want to move the application data as well , so i can install and use more apps.
I tried ArcKnight Kernel , Lupus Kernel , Advance Stock Kernel , and all didn't work.
I am using Xperia Ultimate HD 3.0.2 ROM.
Could it be rom related ?
You must have an ext partision. In recovery you find that option but you must use a rom and kernel that support .ext partision
to create sd ext use MiniTool Partition Wizard then you dont format sd card
I did already try ext3 and ext4 and if you read my post I did mention that it allows moving applications and mount2sd shows the sd-ext partition, it just does not allow data to be moved

I had the same problem in the past! I deleted my sd ext partition with minitool partition wizard after that I make a new sd ext partition and I switched to px recovery from Phiexz and the problem was fixed.

Any ideas
try to use px recovery 0.3.6 beta or cwm 5.0.2.6 / 5.0.2.7
these are the most stable recoverys i used
- Save everything you care from sdcard
- Delete all the partitions
- Re-create partition table (msdos)
- Create a first partition (fat32, primary, will be seen as sdcard)
- Create a second partition (ext4, primary, will be seen as sd-ext)
Questions?
