[Q] My SD Card cant make an A2SD Patition

Hey guys - i just bought an awsome SDCard, a 32GB class 10. just put it in ma HD2 trying to partition it in recovery mode - but after partitioning, the phone (through titanium backup) the phone only sees the fat32 partition and not the sd-ext partition. now i'v tried using PC Software to partition and the tutorials all over but that doesnt help either.
what am i missing? i need help

Hi,
Did you partition in CWM with 1024M and 0 swap ?

simple idea/rule of thumb; class 10 cards are **** and you don't notice an increase in file transfer due to the limitations of the phone itself

Install ubuntu on your windows pc using the wubi installer (google is your friend here), it's very simple to do. Once you have ubuntu linux installed, go into the software center and search for 'partition manager' or 'partition editor'. Then install it. It should be listed in system tools as GParted. Plug in your sd card thru a card reader or a digital camera or another phone, and unmount it in gparted. Then create a new ext4 (probably 1 gb/1024mb) all the way to the right side of the space shown for the card in GParted. Then when finished click apply changes near the bottom of the GParted window. Done
Your phone won't show you that it sees the ext partition, that's all done behind the scenes. The only way to know is to install apps, and watch the system memory in settings/storage. If your memory goes down significantly as you install apps, something has gone wrong. If it only goes down a little (maybe 1-2 mb) after installing a bunch of apps, then all is well and working properly.

@ Malybru - no, my partition is 2048MB Ext - 256MB swap.
@huggs - that is strange because before i had an 8GB class 4 memory card - i had created a 1024MB partition and when i ran titanium backup - you could see the sd-ext partition below SDCard and Internal Storage
additionally, with the new cardz during every data wipe it skips the SD-ext saying that it cant find it - which never happened with the old card so thats why i believe that there isnt one

Weird. I've used quite a few different roms and have never seen the ext partition in storage settings. Wish I could tho.

its not that you could see it in storage settings.. but you could see it in titanium backup and you can mount it in recovery mode

Oh, I didn't know that about Titanium, thanks. I'm gonna have to take a look, for curiosity sake if nothing else

[Q] Quandry regarding SD large file storage for custom ROM install (Phiremod 6.3)

Hey forumers, first post, hope someone can help!
So I'm running Phiremod 6.3 (latest stable) as a custom ROM install on a Nook 1.2 (repartitioned to 5GB /data) and I have a nice big 32GB SD card. I want to put large video files (.vob, 4-6GB) on the SD card.
FAT32 won't handle that, so I formatted the SD card as ext4 (Windows Vista user, so kinda proud of myself for that
Nook won't see the SD card. Back to google, and I read that the first partition needs to be FAT32, then the second (ext4) partition will be mounted as /sd-ext.
My question is - if I repartition the SD card to a FAT32 first partition with a second ext4 (or ext3, that will work too, max file size is 16GB) partition, will I be able to use the ext4 partition to store and access my large video files?
I've been researching, and I'm confused - is there a CM7/Phiremod install/option specific to ext4, or should it be able to see it "naturally"? Does the ext4 partition become an expansion of the /system partition, as some posts suggest? All these questions, and more, can HOPEFULLY be answered by some kind soul flitting across these boards!
And if anyone has a suggestion about a better place to post this question, please let me know!
Cheers
PatMan
Update: I put a 1GB FAT32 partition on the card, then formatted the rest as ext4. I could then mount the ext4 partition using the command line on the Nook, and I could see all the files.
HOWEVER, when I go to play a ~5GB file, it only plays the first 20 minutes. Sound is synced, all files are DVD rips therefore 720, looks fantastic - but why is it not playing the whole file? I'm using both arcMedia and RockPlayer, same issue in both. Using different video files (seems to be OK with files <2GB), same issue. Files can be played on other machines, so it's not the files.
Is there some sort of Android system file size limitation causing the problem? I'm pulling my beard out here, any help greatly appreciated!!

[Q] SD card broken after partitioning ?

Hello xda !
I really don't understand a word about partitioning, but without the App2sd integrated in ICS and CM9, i really got a lack of space for my data.
So I tried to partition my 16GB sandisk cl4 sdcard with rom manager (i don't even know if the rom does support it...) in a 512MB partition size and 64MB swap size.
But now, my sdcard isn't recognized by my phone, and unable to be mounted. In CWM recovery, I can press "mount sdcard" which means it is not mounted yet, and i get an ERROR. :crying:
So i've got two questions:
- Is there a way to repear my sdcard (maybe by re-partitioning it in FAT32) and make it recognizable by my computer ?
- Is it possible to expand internal storage in our defy with CM9 to do Apps2sd ?
So if someone could help me, it would be...GREAT ! :good:
Baxt, an xda-lover.
PS: the data in the card had been saved on my computer so no problem about recovering it :victory:

Thanks i'm on windows so i'll try with mini tool partition wizard =)
EDIT: I chose FAT32 for the whole card, but should i choose logicial or primary ? What does that mean ?

Only use fat32 for primary....for secondary...use ext2 it will b fast.....but note then that partition will not b recognized in windows.....
Oh Nd...primary is d part where u will have ur songs n all...leave it to abt 13 gb.....d Rest format to ext2 and den use link2sd on ur phone....
N I wouldn't recommend swap on a cl4 card....it will significantly reduce ur card life....

Ok so I've Made two partition with mini tool partition wizard:
1 - FAT32 of 13.5 GB as "primary"
2 - EXT2 of 1.4 GB as "primary" too
Il choose "apply", each time it's a success but the EXT2 partition disapears and the FAT32 one takes the whole card (14.91GB) instead of the 13.5 I asked for.
Then, on the phone the sdcard is recognized as "damaged" so the phone ask me to format it, then I press ok, but I still have 14.91GB assigned to the UMS (Mass Storage) and no any 2nde partition (according to the Link2SD app).
What am I doing wrong ?
But really big thanks to you, my sdcard is working, that's the important !
(sorry for my bad english)

Choose logical!!!

For the EXT2 ? Already done, same result...

Sorry I don't have a PC to see d steps...but as far as I can remember...if u r using minitool ...den u need to click apply in the top left corner for every action.....
So...just format ur card again....den do delete all partitions...den partition ur card again....primary as fat32 and secondary(don't remember seeing logical...maybe so in newer version) as ext2.....remember to click apply after every step....oh btw one more thing....windows will not detect ur second ext2(which is a Linux fs) partition ever .....therefore mini tool will show dat part as unspecified or something.....just put it on ur mobile and run link2sd .....n select ur SD ext partition type(ext2) in d menu dat pops up......

Thanks, i know what I was doing wrong, I have used a usb cable through my phone instead of an sdcard adapter.
But now i don't know what I did, but my sdcard isn't recognized anywhere, even in mini tool... That's kinda anoying...

Just use an adapter to connect it to pc and reformat the SD card. Delete all the partitions and keep it to one only (primary).

I can't ! It doesn't apear in my computer (by adapter or USB) I can't see or do anything on it, from phone or computer...

Questions go in the Q&A section

Sorry I didn't really see it as a question.
But anyone could help me recovering my micro-SD ?

Best partioning tool is gparted. There are a lot of boot able CD images containing it. Or use a live CD (or on USB) of Ubuntu.
Try an adapter (maybe loan one from someone). See any link2sd guide for how.

Just google 'sd card isn't recognized' and are some tips on a makeuseof website.

ok, you need to use minitool partition wizard to partition your sdcard perfectly and when you convert the partition files system, please dont forget to convert it to primary partition, also minitool can do that!

Fix broken internal storage on GT-I9000M (/dev/block/mmcblk0 corrupted)

I bypassed dead internal memory on a GT-I9000M.
Symptoms:
- Your GT-I9000M is not booting or bootlooping no matter what firmware you are flashing it with.
- In recovery, you are seeing I/O errors on /dev/block/mmcblk0p1
- Trying to repartition and format the internal storage with fdisk or parted and mkfs.whatever fails.
To recover:
- Partition and format your 16GB+ external microSD with at least two primary partitions, vfat on the first one and rfs (or whatever fs is supported by your firmware) on the second one.
- Acquire a stock ROM, in my case I used JL2
- untar the PDA portion of your ROM of choice (you want zImage and factoryfs.rfs)
- Extract initramfs from zImage ( https://github.com/mistadman/Extract-Kernel-Initramfs )
- grep for /dev/block/mmcblk, there should be 4 .rc files containing references to it as well as within the binary file /init.
- use a text editor to replace all occurances of "mmcblk0" with "mmcblk1" (and vice-versa if you feel so inclined) in the .rc files.
- use a hex editor to replace "mmcblk0" with "mmcblk1" in /init.
- create cpio archive of your modified initramfs with `find . | cpio -H newc -o > ../initramfs.img`
- repack kernel and initramfs ( http://forum.xda-developers.com/showthread.php?t=789712 ), you should have a new_zImage now.
- Mount the factoryfs.rfs as a loop `mount -o loop,rw -t vfat factoryfs.rfs /mnt/loop`
- Modify vold.fstab - this topic is well covered elsewhere (swap sdcard and sdcard1, swap mount points), then umount your loop
- Flash factoryfs.rfs and zImage using your favorite method.
That's it! Your phone will now boot and complain forevermore that the external memory is corrupt. ToDo: use third partition on external microSD as external_sd...

To recap:
We're telling android's init and whatever .rc scripts contain references to the broken partitions on the internal storage /dev/block/mmcblk0 to point to an appropriate partition on the external microSD card /dev/block/mmcblk1. You can actually do anything you want with the partition structure as long as it's consistent throughout init and in vold.fstab. Different ROMs do it differently.
I am not responsible for misuse of your hex editor, lack of backups, etc. I highly recommend the unbrickable mod.

Corrupt internal storage
Hi b0nafide,
My internal storage is also corrupted (i9000). I'm getting the same errors you descripe in your post. I'm trying your solution in wich you install android on your external SD. I bought a 8GB cat10 SD card....
But I'm stuck at the step: 'Extract initramfs from zImage ( [//github.com/mistadman/Extract-Kernel-Initramfs] )'. When I start the script nothing happens, except for my terminal closing. I'm using a virtualy installed Ubuntu distribution (Backtrack 5).
Do you have a tip? Perhaps you can help me through Teamviewer???
Hope do hear from you... I want to use my phone again
Greatings, Eldoro

My sgs is dead.
Please b0nafide, can you upload this modificated kernel (zImage and factoryfs.rfs) just for noobs like me?

Yes that woud be great. ..

Yesterday, I made a flasheable pack of JW4, but it doesn't run. Now i'ḿ trying to modify JVU, but a strange thing happen when i'm repacking zImage...the script spends a lot of time in order to make it, and i can't be able to verify the correct pocess of new_zImage.
It's my first post in XDA, because normally I use HTCMANIA... I'm Spanish...and my English it isn't so good. Even, I should said that it isn't my phone...i'm repairing a friend's phone, so it's difficult for me to explain or speak about different ROMs or kernels....sorry
It's very important to advice that the scripts posted should be modified to get it run...because I found different problems to execute on Ubuntu.
Now it's 1:30 am...i'm trying "ext_JVU"....tomorrow i'll tell you the results.

I will try this layout. At first I prepared sdcard with 2 partitions which currently boot into Android but storage isn't working:
1st primary fat32 (6gb)
2nd primary ext4 (2gb)
You said raiserfs, should be that rfs type partition?
Update: I just noticed that both partition on my sdcard are fat32. First partition which should be internal storage I had to format again (not sure why). After this internal storage is still not available when in Android. I guess some mounting point is not good. Second fat32 partition is where the data is I guess (picture attached)

Exactly the same result as grozni. Same errors upon installing but booting into android. Amazing work! Also formatted 2 partitions. WiFi also not working btw. Hangs on obtaining ip...

Is imposible to start Andoird without a rfs partition to mount /data (or ext4, for ROMs wich has fixed the troubles with ext4/rfs file systems...)
I can´t start the phone, because i get an added problem (my system can't format rfs data..but i don't know why)
I'm going to review the file /system/etc/vold.fstab who manages the mount points of the internal and external storages.
If anyone gets the correct configuration...please post it..
Tomorrow is Monday...and although I'm Spanish, I have a job (****ing crisis)...and i haven't so much time as weekend
Edit: wifi sockets are created over /data partition, if there is any problem in this partition is probably to get troubles obtaining IP

If I understand correctly samsung rfs and reiserfs are not the same thing? Why you use raiserfs on sdcard layout?

[How-To][P3100][CM11][dataOnExt] use second partition of external SD-Card as /data

Hi,
I was looking for a tutorial how to use a second partition of the external SD card as /data partition. 1 day and about 10 complete system wipes later...
How I mounted the second partition oft my sdcard as /data:
You have:
a P3100 (not tested on others yet)
Cyanogenmod 11 Rom
a fast micro sdcard -32GB
Step 1 prepare the sdcard: you need a fat32 partition and a Ext4 partition (use a PC with a cardreader and gparted or something like that)
Step 2 For the sake of simplicity, I am going to assume you already installed your rom and the tablet is rooted
Form a terminal with su:
create a directory
Mount the second partition (/dev/block/mmcblk1p2) on that directory
copy -a -v /data/* yourDirectory/
Step 3 - modifing the rom and fstab.espresso
Now you have to extract the boot.IMG Form your rom, using dsixda's Kitchen
In case you have no idea how to use this kitchen (like me) here is someone doing exact what we need
After changing in the BOOT-EXTRACTED directory, you have to edit the fstab.espresso...
simply replace the mount source of
Code:
/data
with
Code:
/dev/block/mmcblk1p2
save the file and rebuild the rom
Step 4 install your new rom with cwm and reboot...
If everything went well the second partition of your sdcard is now mounted as /data
My internal storage is now (in the storage view of settings) about 20GB big and i will never have to use link2sd or apps like that again
Nice side effect the access to the highspeed sdcard is a bit faster than the access to the internal storage
You have to modify all updates oft your rom in the same way before installing them
ToDo write a script to automate the process
PS.: plz tell me if something is unclear or not understandable or this is the wrong place for this thread OR you know a shorter way to do this (thats my first post here)

Happy modding! Feel free to quote any or all of the thread, just give credits where it is due
On a related note - have you confirmed this to be working in your device? And does your device use a part of the /data partition as internal SD Card (/data/media fused to be /sdcard)?

OK thank you,
Yep its working, the complete /data is on the sdcard now including /data/data and /data/media, my internal storage is now about 20gb big xD
I am not really sure if there are crazy symlinks in /data but atm i have no problems
The "real" sd partition is still fat32 formated and used as before the modification, and because i didn't mount the second partition anywhere (only as /data) the rest of the system doesn't know that it exists...
(problem: there is now a unused /data partition on my internal tablet storage and i have no real idea how to use this free storage)
