Understanding storage under E4gt - Samsung Epic 4G Touch

I have my 32gb card partitioned with 27G FAT32 (primary and first partition), 2G EXT4 (primary and second) and 32MB of swap (third). This used to work fine with my old EVO but the 2G is unrecognized in my e4gt and I've not seen a way to get it working. Moreover I don't understand how the 27GB and emmc are being used or referenced.
The /emmc shows up as only 1.23G (?) as does /sdcard. There is also an /sdcard1 with 4.47GB, where the hell these values are coming from I have no idea since they don't correspond to any of the partition values. Under settings/storage the1.97 internal storage, the 11.5GB og internal storage and 27GB FAT32 shows up. I can't figure out how they correspond to what's in /emmc, /sdcard and /sdcard1 and I have no idea where the 27GB FAT32 partition is supposed to be in the actual file system you can explore with root explorer, the 2GB partition doesn't show up under storage or under the file system at all.

Sounds like you are running cm9.. it doesn't support the ext4 partition on our device, as their is no need. Swap is also not supported. As far as confusion about the rest.. try a newer build..

[Q] Using G1 Sdcard with G1 partition setup should I format?

Hey guys I am using my sdcard from my G1 with an ext3 (maybe ext4) partition, a swap partition, and a fat32 partition. Should I format and just leave the fat32 partition? or should I just delete the swap partition? I figure I won't need it since the Vision has 512mb ram. Thank you.
you also don't need the ext since you have nearly 2gb of storage accessible to you.
format to just fat32 and you'll be golden

Help me fix my SD Card

Hi there,
A couple days ago, I had a usb brick. I quickly fixed it, everything got back to normal except for my sd card : I think it's corrupted. Why do I say this ? Because I've got another sd card, and it's working perfectly. I can't get to format it via Gparted. It says the procedure failed, there was an issue and i couldn't format it. In addition, even though it's a 4GB card, it's recognized as a 3gb card.
When I try to use it in recovery mode, it says :
Code:
E:Can't mount /dev/block/mmcblk0p1 (or /dev/block/mmcblk0)
But when I use the other card, nothing weird happens.
I'd like you guys to help me repair my SD card.

Googled and found this: http://www.ehow.com/how_4850280_repair-corrupt-sd-card.html
1. link your desire with pc
2. enter "FASTBOOT Mode", it will display "HBOOT USB PLUG"
3. open dos windows and type adb shell
4. type fastboot oem rebootRUU
5. type fastboot oem enableqxdm 0
and retry
I already tried this, but it didn't work out ! I'm out of ideas...
So it says it's a 3GB card? You had an 1GB Ext partiton before?
If yes, that's where your 1GB's gone.
Recommended is to repartition your card again from scratch - Using Either GParted, EASEUS or MiniTool partiton.
Backup everything from it, then delete all partitions - and re-create them.

Actually, it's 3.7 GB and not 4GB (I guess it's normal though). And yes, the missing space was from the ext partition. Thanks god, the first thing I did was a backup of my SD card. Yet, I tried to format the card with Gparted (I'm currently running Ubuntu 10.10) but as I said above the procedure fails.
Then, I formatted in Windows, and I managed to create a 3Gb fat32 partition recognized in Gparted.
But how am I supposed to get my missing space back if this space isn't recognized in Gparted ?
I'm using Ubuntu 11.04 (natty) - and i'm able to mount my EXT partiton of the SD Card.
As I said, don't just format the card, but delete all partitions and re-create them, then format them.
Also, if your card is messed up badly, maybe you have to use the termina with commands to recover the ext partition.
Always format SD cards with the "SD Formatter 3.0" from the SD Association: http://www.sdcard.org/consumers/formatter_3/
This little programs formats the whole card (full capacity, erasing all other partitions) in FAT32 meeting all SD specifications.
Furthermore it alligns the LBA parameters (virtual heads, cylinders etc) and the fat32 parameters with the internal structures of the flash memory (eraseblocks), so that fat32 clusters never overlap eraseblocks. This speeds up write performance (in my case about 50%! ).
There is no better tool to format SD cards.
After that you can resize (But don't move it, just trim the end. The free space in front of the FAT32 partition is part of the alignment) the FAT 32 partition with gparted and generate an ext partition in the free space.
Finally one should run the ext alignment script (it's a zip for recovery mode) from baadnwz homepage (http://www.baadnwz.eu/2011/05/align-your-sdcard-fat-and-ext-partiton_16.html) to align also the ext4 partition to the flash cells.
boot up into android (with any ROM) and go to settings > storage > format SD card
this should restore whole SD as FAT32
funny enough Android could do it, while Gparted could not (gparted didnt see my whole sd, it didnt see the ext partition)

---> As I said too , Gparted fails to create partitions. It displays a "warning" icon by the sd icon. Unless I'm a fool, I can't get any further there.

---> Yeah, Gparted is a bit lazy here.... Gonna try it if hypophysis's method doesn't work out. I gotta admit this kinda problem is pretty disturbing and pisses me off so much.... Waiting forward to get it over with.
Anyway, thanks a lot for helping me, you're good people here !
Well, I tried hypophysis's method. It formatted successfuly. But as you said, I had to run Gparted again in order to create an Ext partition next to the fat 32 one. But I couldn't --> It says it couldn't find the "first sector" I guess, and it couldn't determine the device specifications, it wasn't able to perform everything he wanted. Actually it recognized the whole sd card, but wasn't able to do anything with it. I couldn't unmount it or mount it....
I'm stuck at square 1 Gonna try to perform dzumagos's method later.

[Q] Ext Partition

Hi
I am having trouble to make my phone recognize my ext partition
THis is what I did ...
Format sd into FAT32
Use Gparted to resize FAT32 into a 6.4gb and 1GB ext4 and 32mb linux swap
And i wiped all data and installed the ROM(Reflex S 2.1.5)
When I boot into ROM, and go to Setting->Application ... i see i can use only 134mb as internal disk space
But in Storage and Mounts I can see that there is 1GB of ext partition
Please help

Your phone recognize the memory since in Settings it tells you have 1GB. You need to use a script called A2SD+ to be able to use that memory. The script will move almost all applications to that partition, but still use some of your phone's memory so you don't need to worry. This is normal.
But I did do the same process for my friend ... Installed same ROM and it recognizes his ext as internal

Are you sure the partition is formatted correctly and the ROM you are using supports a2sd+?

I am using reflex s 2.1.5 and am sure my partition is correct too

I can see
Total Space - 6.4GB
Avlbl SPace -6.15GB
Available on ext partition - 616mb
INTERNAL STORAGE
Available Space on /System - 9.13mb
Avialable Space on /Data - 130mb
Try reformat your SD card directly from GParted. So you enter in gparted, delete all partitions, make FAT32 Primary (First), make EXT4 Primary (Sencond) with no space between the partitions.
Also do you have installed A2SD+ script??

Move sd-ext to a new memory

Hi
I want to upgrade my sd card, I have a vfat partition of 3GB + 1 ext4 partition of 1GB at the moment on my card.
If I upgrade to a bigger sd card, and create same partitions (just different sizes) on the new one, move data across, does android complains?
Should be ok, as long as the device of the partitions are the same, no?
Thanks for the tip

yes man this is ok you can make different size parts but keep type (vfat, ext)
also you can keep the old sdcard until finish your job just to be sure about !

[PROOF OF CONCEPT] Full swap SD card for Xperia M/M Dual

Hi all,
After searching on the net and a bit of thinking, I have an idea about fully swapping the SD card with internal storage.
In my concept, I will divide the SD card into 2 partitions:
- 1 FAT32 partition for compatibility with other apps and the device itself
- 1 EXT4 partition for swapping
Then, I will inject a small code to the system to run during boot (I think I will use init.d) to unmount /data partition (I don't know if it's necessary) and remount it to the EXT4 partition.
The best part of this method is it's simple, more efficient than Link2SD (since it makes the /data partition gets fully hooked into SD card in no time) and also makes boot up progress faster (no apps check and relink)
If someone can help improving the concept or even turn it into a prototype or a real stuff, leave your ideas at the comments.
Thanks.
too good if this can really be implemented... if someone knows how to do it...please comment
Instead of mounting the sdcard as Data Partition, i would instead Turn of the sdcard Emulation, since the sdcard has lower rw Speed what would slow Down the Phone.

In fact, the internal EMMC storage is even slower than a SD card. Plus the sdcard emulation is a function implemented into Android kernel itself, while I'm just adding the code. And this is NOT for speed, it's for storage.
