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!

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

Guys, After a while i'm using my htc desire hd . I downloaded the new rom n copied to sd card. booted phone to recovery mode.
as usual wiped everything. some how Sd card is not showing up. it's says not mounted. even i tried to mount it's not mounting either.
with Samsung I could use Odin to flash a new recovery or rom.
I don't know what to do with htc desire HD ?
any help plz
Get the pd98 zip and install thru hboot. Then see if you can do it over again. Are you rooted or not ?
Also did you format SD on computer or on phone. If you did a true full wipe meaning SD as well then your ROM is no longer on card. After full wipe you need to mount USB then copy ROM to SD then flash ROM.

Yes the phone is rooted. n currently using a custom ROM. some how thought of flashing different rom. now stuck at recovery.
curently cwm is 5.0.2.0
Just wondering how can I flash a newer version of it...
In recovery do a full wipe
1. Wipe factory
2. Wipe cache
3. Wipe dalvik
4. Format partitions (except SD card)
5. Format SD card
6. Mount USB
7. Copy ROM zip to SD card
8. Unmount USB
9. Install from SD
10. Flash ROM
11. Reboot
All done from within recovery. Do not exit recovery till all steps complete

I've already copied the ROM into SD card. it's 32 GB Sandisk class 10 sd card.
I have done all those steps but I get error : E: cant mount /sdcard/
Did you try reformatting SD card on computer or even try another card if you have another one.

Hey everyone,
I have recently rooted and S-OFF my HTC Desire, using Revolutionary.
I have partitioned my SD card and installed Mounts2SD application from Google Play store. Busybox and Init.d seem to be configured ok but still, Mounts2SD doesn't seem to work and I can't get my applications to use the 1GB partition off memory that I have dedicated on my SD card.
Some help would be much appreciated!!
Thanks a lot in advance...

1. How did you partition your sd-card?
2. Did you configure m2sd correctly?
3. Are you one of those guys who think that the internal memory itself will be larger, thus expecting to see "1148 mb" of internal storage in settings? You will still see 148 mb, but the partition will be there, doing its job.
4. What did you move to sd-ext? Try moving app and dalvik cache.
Hello,
1. To partition my SD card, I booted the phone in recovery and I partitioned it from there. And I know it's done because my SD's memory is now 1GB less.
2. All the boxes in m2sd application are checked. It doesn't let me change anything.
3. I didn't expect to see the internal memory larger.
4. From what I read, I thought that after m2sd is configured, it will move the applications itself to sd-ext. So by still seeing 126/148MB of my internal memory occupied, I suppose this didn't happen. How can I move an app manually??

In the Content section, select "Application" and "Dalvik Cache".
What recovery do you use?
I tried checking the dalvik cache and also data, but not only nothing changes, also every time I reboot the phone it goes back to the original settings: only application is checked....

Ok. That explains it. Your sd-ext wasn't done properly. Check my guide for correctly partitioning your sd-card :
http://forum.xda-developers.com/showthread.php?p=37383522#post37383522
Then use the mounts2sd flashable zip. It's safer.
http://forum.xda-developers.com/showthread.php?t=1342387
I have followed your guidelines and installed 4Ext recovery. Then i partitioned my SD card with that and i installed m2sd using the flashable zip.
Then still m2sd not working and i'm still getting the annoying low space notification. So i installed FreeSpace and it seems like i don't have an ext partition. The only things it shows there are:
- Cache 40MB
- Data 147MB
- SD-card 2731MB
- System 250MB
My SD card is 3.66GB. So from that, the conclusion is that the partition was created but the system cannot access it..?? What could be wrong?? How should i proceed? Just try to partition the SD again??
Thanks a lot

Yes, partition your sd-card again.
1gb goes to your sd-ext. It's normal for freespace to show 2731 mb.
For some reason my phone couldn't access SD-ext, even if it was partitioned correctly and in recovery it could see it. So i wiped everything and istalled a new ROM. Now it works perfectly!
Thanks a lot for the assistance!

Pls help me: I wanted to intall int2ext and was saying that no app2sd partition found(when formatting /sd-ext) so I used this tutorial to format my sdcard: http://androidandme.com/2009/08/news/how-to-manually-partition-your-sd-card-for-android-apps2sd/
I made it.(I made the ext partition in ext4 but after this i saw that you need s-off to work +it was not booting...stuck at the HTC image or at the ROM boot image. I downgraded to ext3--removing ext4 partition and adding an ext2 one , than upgrading it to ext3). All worked fine, the phone was booting e.t.c. Everything was fine. Because i had the app2sd partition i installed int2ext and formatted /sd-ext. (all worked fine)Then I pressed on Reboot now(in recovery mode) and again: is not booting up. It is stucking at the HTC Image or at the rom boot image.
What to do to install int2ext and to make it work without any problem?
Thanks in advice.
