[UPDATE] Weird problem with sd-ext --> PROBLEM SOLVED!?!

itasoulas · Dec 22, 2011

Ok, I am on vo-1's CM7.2, this also happened with ICS2/Final.

SD-EXT worked great, I linked my data with link2sd and after installing some apps the partition is empy. Same thing happened when I used s2e in the past. I look at the sd-ext folder and there's nothing there. With link2sd when i try to create link for new installed apps it says that partition is read only. I checked permissions, everything was ok. Formating the sd-ext solved the problem but this is not a solution as all apps there can vanish at any time.

I checked that with 2 different sd cards, they are not the problem. I create the mount script with link2sd as ext3.

Can anyone help me on this one? I am tired of facing this again. Am I doing something wrong?

Something else when a card is partitioned through CWM 5, does this create a script for the card? Is link2sd causing a problem when it mounts the sd with ext3? HEEEEEEEELP!!!!

Delete all partitions of your SD Card and Repartition it. It woks for me a 2 weeks ago with same problem.

I don't think that will do, this card was out of the box formated and partitioned through CWM...

The thing is that I didn't even had the chance to backup my sd-ext partition cause the folder was empty!!!!! Does the oc kernel by ketut causing the problem? Just thinking...

Did you su before checking folder? How are you checking it's empty?
Mine is working fine with ext 3 type partition.

a dev's help would be great here. Either the card is not formatted properly from within CWM, or this is CM7 issue or... I really don't know. It's things like this that make me tired and wanna go back to stock rom where simple things work.

Honestly, can someone provide with a solution cause as I read in other phones forums this thing with CM7 is also there!

I decided to partition sd with this http://www.partition-tool.com/download.htm
Great tool but a bit tricky to use

So I succesfully created one fat32 primary partition and one EXT3 primary partition. Maybe I'll test it again with CM7.2 tonight and link2sd to see what happens.

I'm having the problem when partitioning through CWM so I don't think that will help you. Also Know that you said that you had partitioned with mini tool I don't think that easeus will also do it for me....

Still no response from a dev... too sad!

You can backup your sd ext via Linux OS or just VMWare and a Ubuntu vm. Last time I have made a backup and formated the sd ext with mini tool and it start working again. But now I don´t want to format but find a new/better solution. Somewhere I´ve read the read only problem is caused by canceling the sd check and you have just to run it through...

Prawesome · Dec 23, 2011

Since this problem is happening with various roms,it isn't a problem with the rom.
Try converting ext3 to ext4,this is not guaranteed to work but try it

[UPDATE]Weird problem with sd-ext --> PROBLEM SOLVED!?!

OK...PROBLEM SOLVED!!! (At least for me) So here's the story...

1. I used this http://www.partition-tool.com/download.htm to partition sd. One primary fat32 and one ext3 1024MB partition. So I was sure sd was formated and partioned correctly (be ware, this program is a bit tricky but I am not gonna guide you through this - tricky at first but not difficult). Just make sure that the cluster size for fat32 should be 32KB and for EXT3 4KB. You should have something like this http://imageshack.us/f/810/65663741.jpg/ Partition sizes depend on your sd size and how much space you want to have on sd-ext. Just showing this to see what the outcome of the process must be.

2. Then placed the card on phone, started in recovery and then did a full wipe. As you know, when you wipe data/factory reset, sd-ext is also formated. I wasn't sure though what file system does CWM use to format sd-ext, that's why I did leave the sd on the phone.

3. So while in recovery, I pulled the card out, checked the card with Easeus and found that the sd-ext partition was not formated with a known file system, it said partition unkown!!!!!!! So I formated sd-ext with Easeus as an EXT3 again and put back in phone which was still in recovery. Then started to flashing things.

So far, everything is working great with link2sd (mounted sd-ext with ext3 when app first started - then reboot). I tested the hell out of it, created links for apps, then remove links, move apps to phone and opposite, lots of reboots and shutdowns to check if the sd-ext will stop working....After 180 apps phone works great, sd-ext is still there.

BOTTOM LINE
I think CWM has a problem when partitioning sd/formating sd-ext. Bottom line is when doing a full wipe, don't have the sd on the phone. Format and partition it with Easeus (or one of your choice) or delete files/folders you don't want with that. Remember, both FAT32 AND EXT3 should be PRIMARY!!!

i already create partition using CWM ... y CWM format my sd to ext2?

GerasVille · Dec 25, 2011

First you have to flash rom and after this let the Ace in CWM and format the sd via mini tool and insert it again. Then just reboot and enjoy
