Hi all right i seem to have a issue with 4.4.2 where for some madding reason Apps like Mount2SD and Link2SD are not working at all.
I have made a EXT4 Partition on my 32GB Micro SDHC card U-1 Class 10 in the hope of placing the Apps such as games into it so as not to fill the Internal SDCard up.
With it only being 16GB and all with Music etc it fills very quickly especially when some of the game i play are like 1.9GB in size after downloading the apps data.
I am not even sure if the current kernel supports EXT4 either. So can anyone help me on this as i am sure it will help other members. I am planning on getting a 64GB SDXC card some time and then dedicating a full 32-48GB just for Apps and Data but i want to see if it will work first on the 32GB SDHC card first.
Thanks in advance.
i'm sorry to bump this very old thread but i have the same problem as well. i partitioned the microSD card with ext4 and everytime i try to use Link2SD or any similar app, the tablet restarts.
I'm using the kernel made by shaky, and i'm on Lollipop

can someone please help me?
I have tried many builds and they are all unusable for me when they are using SD partition.
Disabling it makes it usable again but no user space!
I have tried CW method of partitionig and GParted but always same result
My SD is Class 2, don't know if that is problem... tried many times to format it... tried many NAND ROMs.
Please help!!!
Brand, size of your sd card?
What format? Windows?
File system used in ext partition of sdcard?
Try a HDD benchmark test on your SD card. If sustained write is less than 2mb/s, then you want to use SD Card Formatter 3 with ERASE FULL (ON) and RESIZE (ON), if still slow, time to buy a proper sd card.
i noticed it by myself. got a 16 GB class 2 SDcard and since NAND-roms its really messy, changing the screens by sliding (stuttering - and gets worse the more apps are on it), loading apps are much slower than with SD-roms.
i ordered a 8 GB class 6 SDcard last friday, hope to get it tomorrow. will check it out with a fresh format and install asap. will come back and post my experience.
It's Kingston Class2 16gb.
First partition is FAT32 15gb, and second is 1gb EXT3 (also tried with EXT2 & EXT4).
It's strange but I remember that SD builds were much generaly faster (thats not the case when I turn off this partition).
Here are results:
Read 10.130 MB/s
Write 2.163 MB/s
I think they are good for Class2.
Any opinion is welcome!
Eww.. Kingston MicroSD.
You're right, their speed scores are pretty good. Stuttering is usually caused by slow reads, writes don't cause stuttering, except mainly when installing apps. Your card isn't corrupted, because the speeds are exactly on spec.
Well, the first few days of using ext partition on SD card for A2SD+ is going to be slow, till everything is written on the SD card, then it speeds up considerably. I recommend, try using it for 2 days, and see if you can't stand it.
SD builds already have everything in the SD card, including data.img where userdata is stored. However, with A2SD+, everything is in the NAND, but the application will move to SD Card ext3 partition, at the same time the Dalvik is also being moved there too. So yah, it can be slow, until everything is done scooting over.
My main problem is I have LOTS OF APPS. Because of this, I have to move them to the microSD card. The apps I usually move are the ones that eats up lots of space like games.
I've noticed another problem when I started moving the games unto my microSD card. Since the games has music files as well (like sound effects and in-game songs and whatnot) whenever I open a media player such as Ubermusic for example, I've noticed that those game music files also gets detected by Ubermusic. Because of this, whenever I choose "Shuffle All" and play all my music there would be times that I would hear Angry Birds squawking and them evil pigs getting smashed mixed in with my songs. (^_^") It has grown into a huge problem for me, since I can't move them back to the /data partition as there isn't any space left in there.
Currently, I use App2SD Pro to move those apps, and I hate it because even if you choose "Move All Apps" you still have to manually move them by pressing the button one by one and it has been so time-consuming. Because of this, I've been on a search for a proper solution.
Please correct me if I'm wrong.
Based on my personal research, I believe that we can partition the microSD card in such a way that it can have a /data partition of it's own, and that's what we call SD EXT right?
If that's true, does that mean that if I have this set up in my microSD card and my /data partition is full of apps, will the next app that I would install automatically gets installed to the SD EXT? Or do I need an app like Link2SD (based on my own research, I believe this app requires an SD EXT to work properly.) to manually transfer the apps that would not fit in the original /data partition?
And can someone please confirm-- since the app "Link2SD" says "link", does this mean that it just "links" or creates a "shortcut" in the microSD for the apps or does it really move the apps in the microSD?
And last but not the least, can someone point me out to the right direction where I can find an easy to follow guide (if there's any) to be able to create an SD EXT partition in my microSD card.
Oh, and by the way, I have a 16GB Samsung SDHC Class 2 microSD card if that would help.
Thanks in advance for all those that would help out! This community has never failed me, and I'm proud to be a part of it!

I may be new in posting, but as far as I know: SD-EXT is the whole sd card itself when your device does support internal second usb storage (also named sd card). That is the case for my Galaxy S2 where SD-EXT only refers to my EXTernal (i.e. removable) sd card; there's a fixed (internal) sd card too.
SD-EXT does not mean anything else for me.
Hope that'd be useful.

I'm guessing you are on a custom ROM. You can partition your SD with CWM recovery. If your ROM supports apps2sd it will use the ext partition.
Class 2 is letter used for storage than performance, though.

Hi,
I wonder if someone can help me, I've got WP7.5 install as a NAND installation, with Android 4.0.4 as a SD installation. Both work brilliantly, although I do have some slight problems.
Android won't detect an SD card installed, so I can't use some apps, that require an SD card to be present.
Does anyone know if there is a fix for this, surely I'm not the only person in this position.
Cheers
I'm guessing it's because your SD has been formatted specially by WP, and Android can't read this. Your FAT32 partition is probably too small for anything to be stored in it.
The Fat32 partition is 1.6Gb.
Is it worth making that bigger, or creating another FAT32 partition?
Cheers
Hmm, I'd guess that you wouldn't have any more than 200-300MB free on your SD as read by SD Android then. I don't know how much an SD Android build takes up but the data.img is at least 1GB of that. As for increasing the partiton/creating a new one, I don't actually think that's possible without losing your data is it?
Hi,
Thanks for your help.
I'm not too fussed about losing anything...
Here is what I have just tried without any success.
I have a 8Gb card partitioned like this.
1.*Gb
Primary, FAT32, (Android SD install)
2Gb
Primary, FAT32, (My hope would be that Android would see this as the SD card)
4Gb Other (WP 7 partition)
No luck unfortunately, any ideas?
Cheers
Are you sure you're using an 'unlockable' WP7.x ROM? If so, try formatting the storage card to normal and flash a Android build, see if it utilises the memory card like normal, if it does, then I would say that you're doing something wrong when setting it up.
Just double check each step of a tutorial (example: this one) twice and hopefully you'll only have to flash one more time.
Why do you have 2 fat 32 partitions ?...just use one fat 32 partition..in regular sd android....data image is used as internal memory and fat 32 part as sd card
I believe your second partition is not being recognised...make only one fat 32 partition you don't need two

Sorry but I am new here and have been looking threw as many posts as I can to try to find out if there is a fix for the Infamous ROM not recognizing a 64gb SD card? I have seen posts on the same topic in which I am posting on now with no answer to a fix but since I'm a new member and need to have at least 10 posts before I am able to post on the developers page I am posting here. sorry if this is the wrong area but I'm a noob and didn't know where else to go.
Thank you for your time on this matter, it is just very frustrating to be able to load such a great rom and not have the potential of utilizing a 64gb sd card.
You probably have the card formated as ex fat. You can either flash a kernel that supports ex fat or you can put the card in your computer and format is as fat32. My rom recognized it but I had to reformat as fat32 in order to get a couple 3rd party apps to see it.

I have a ScanDisk Ultra microSDHC 64gb card and when I go to format it, it doesn't give me the option to do fat32 only ntfs and ex fat. Is there another way to format besides going to windows explorer and right click format?
I used a free program called EaseUS Partition Master to format my Sandisk Ultra 64GB for my Galaxy S4. It was quick and easy to reformat from exFAT to Fat32. Hope this helps.
I have installed a Cyanogenmod ROM on my Samsung Galaxy S5 (although I think that my device model won't be relevant) and I want to mess around with others rooms on my SD card. However, my only micro SD card which seems to work as a storage for apps on my phone is a class 10 Sandisk ultra (hc) and I have a couple more class 4 Sandisks which are not in use.
The point is, the only sd card which I think will work as a reasonably fast storage for ROMs is formatted to have two partitions: an ex4 one and another one with a fully system called f2fs. This, as I have read, is not resizable, but there is a way to backup the data and move it to a smaller partition to free up space for another ex4 partition for Multirom. Any help?
