OK so far my problem has stumped everyone.
I have a rooted and hacked G1(HTC Dream) with a 16GB MicroSDHC that is divided into a 2GB Ext2 partition and a 14GB FAT32 partition. It worked fine for a while but then my G1 started to freeze up and reboot continuously so I took the card out and it stopped. I tried chkdsk in Vista and it hung in elevated .cmd prompt and it says i have bad sectors but it cannot fix in read only mode. I tried format in Vista and cmd and it tries, says the data is RAW and that it tried to convert to FAT but cluster size too big. Then when I try fs command for vfat in .cmd it still won't work. I used Paragon Partition Manager 9.0 PAID version to create partitions but now it hangs every time it tries to read the card and it won't format. Tried sdformatter and a low level formatter to and no good.
I have Terminal in my G1 but I am not familiar with Linux commands. I tried fdisk and it says the FAT32 is in read only mode. When I type busybox df -h it won't show the "/dev/block/mmcblk0p1" but it shows the Ext2 partition. But when I type the mount command it shows up as "rw". But i cannot access it at all to wipe the stupid card out.
HELP!!!!
1) can you mount the fat32 partition in you phone and can see the files?
2) did you tried as root *mount -o rw,remount -t vfat /sdcard* ?
Yes I tried it and it doesn't work. Is there anyway to flash the bootloader or the ramdisk?
assuming i have ramdisk.img boot.img and system.img on sdcard root and I want to copy to system files, anyone know the commands in Terminal Emulator?
Download the ubuntu live cd, burn it, then boot your computer with it. Plug your SD card into an external reader, NOT the g1. Run gparted and select the sd card from the list of drives and see if you can format or re-partition your card. If it wont let you then try selecting Device->Create Partition Table, to create a new partition table. If none of that works then either your card or card reader is dead.

Nevermind, it was a class 2 16GB card...i think I broke it...getting a class 6...
need help....
i have a 16gb class 6 and i need help or technically a walk through on how to partition this card....hence i am an extreme noob. i got into parted and it says i have a 16.1 gb so would that translate to 16001 mb? reason i ask is cause i dont know what to subtract 32mb from and such? also what is the optimal set up for a card this size? thanx in advance for any help that you guys may supply me...

hi, i have been trying to get a dual boot with wp7 (hd20 8779) with android jellybean (paranoidandroid) using ext4 on the sd.
i have right now:
magldr v1.13
ext4 recovery nand
partitions:
1st FAT 14gb
2nd EXT4 1gb (made via ext4 recovery)
there is no 'nativesd' folder that i can see on the sd card (to put the jellyb.zip rom in?) and it (ext4 recovery) will not let me install zip from sd (either jellyb.zip rom or dual installer zip. it just says:
Finding update package...
Opening update package...
Installing update...
Installation aborted.
I am also confused about which rom I should go about installing first at this point. wp7 or droid?
---- edit:
ok, i was using the wrong android rom. aokp nativesd worked. booted, tested it, all ok. but then i went to install wp7 and it erased it. wp7 booted, worked. took out sd, hooked sd up to computer, repartitioned to have wp7 ||| fat32 ||| ext4, but then when i put it back into phone and booted to wp7 (to make sure it was still there), it said available storage was entire sd card. so i powered down and tried to boot into android. now android was gone. tried to boot into ext4 recovery and that was gone too.
i am very close now. i just need help partitioning this correctly. i know now that the latest version of minitool will let me partition to ext 4 so that's no problem now. can someone please help me set up my partitions so that i don't lose one installation with another? also, i don't know how to check if something is mmcblk0p2 or how to set it to that. i haven't been able to find any instructions in doing so, just mentions of it across the forums.
please help
Okay.
You probably have WP7 now, right? You've already partitioned the card with xboxmod's CABs, haven't you? If not, please do those two steps before continuing.
Windows Phone 7 wipes entire SD card and creates its own partition every time it's installed or hard reset, and because of that you can't install Android ROM first and then WP7.
After that, just take MiniTool, delete the FAT partition and create two new:
First FAT partition, then on the rest create EXT partition. It should be mmcblk0p2 then, but you want to check it anyway. How to was in that thread:
6. (WP7 users) make sure the EXT4 partition is located @ /dev/block/mmcblk0p2
To check this mount your sd-ext partition in 4EXT recovery and use adb shell or QtADB shell and type df
Click to expand...

If you don't have ADB yet, please download Android SDK where that tool is included. Or try QtADB, but I haven't used that one.
That instruction translates to:
1. Run 4EXT Recovery
2. Choose Mount... option
3. Mount /sd-ext
4. Run adb shell (type that in CMD when in folder with adb.exe, I hope you can navigate with CMD)
5. Type df and press enter.
Then install the ROM using 4EXT SD Recovery. Nothing complicated, I hope. That's how I've done that at least.
thank you

wp7 is installed. after several searches, i'm not seeing the cab files you're talking about. the current partition structure is 200mb fat ||| 14.67gb 'other' ||| I saw that part in the thread with mmcblk0p2, but I had no idea how to specify that when I made the partition or how to check it. Thank you. Yes, I have the Android SDK (had no idea that's where to find ADB) Thanks for elaborating that for me. I am going to do all this right now!
--- edit
how do i check to make sure its mmcblk0p2?
if i just repartition in minitool everything, do i still need the xboxmod cab files i can't find?
--- edit
i repartitioned with minitool and this is what i have now:
1st) 7.88mb (free) 0 (used) unallocated logical
2nd) 5.81gb (free) 11.65mb (used?) fat32 logical
3rd) 1.46gb (free) 101.80mb (used?) ext4 primary
4th) 7.67gb (free) 7.67gb (used) unformatted primary
now, i'm going to install ext4recovery nand and try to install android, is this correct?
--- edit
i'm not seeing adb anywhere. In android sdk tools i have two shortcuts: AVD Manager and SDK Manager. I don't see adb in either. I'm loaded into EXT4 Recovery Nand now.
--- edit
After looking in the android sdk program directory in windows i found adb-has-moved.txt It says:
Code:
The adb tool has moved to platform-tools/
If you don't see this directory in your SDK,
launch the SDK and AVD Manager (execute the android tool)
and install "Android SDK Platform-tools"
Please also update your PATH environment variable to
include the platform-tools/ directory, so you can
execute adb from any location.
--- edit
when i get this completely finished, I'm going to do it again to another phone, and I'm going to make a COMPLETE step by step guide from start to finish for noobies like me and post it.
---- edit
after going to a cmd prompt and navigating to the 'platform-tools' directory and typing adb, press enter, then typing 'df', press enter, i get this error:
Code:
'df' is not recognized as an internal or external command, operable program or batch file.
--- edit
i'm attaching a screenshot, i used the command 'adb shell' then enter then the command 'df'. although i have no idea if this is doing this to my sd card on my phone which has the sd-ext mounted.
Oh, you resized WP7 like that (with partitioning tool), okay, it's fine too. You will have to hardreset though. No need to use CABs then.
ADB is in C:\android-sdk-windows\platform-tools if you've downloaded it (platform tools) from that installer/updater of course.
Browse there with CMD and use adb shell.
Please remember to set both FAT and EXT4 partitions primary, else it won't work.
After you check if the partition is in that mmc02 thing, you can install the ROM with the recovery.
thank you

ok i'm attaching a screenshot of my partitions in minitool. i made the fat primary as well. now i'm going to copy over the aokp jellybean rom and try to install it. fingers crossed! also, i hard reset wp7 when i first installed it. i'm afraid if i do it now, it will undo all the partitioning steps i've taken after that. is this correct?
---- edit
ok, something went wrong, because after i installed android from ext4 recovery nand, i powered down, booted into magldr 1.13 and selected '1. Boot WPH' and it said: 'WPH not installed.' aaaaaaahhhhhh!!!! lol
any ideas where i might have gone wrong?
---- edit
btw, when i booted into android (1st boot) i checked the space, and it said the 5.81gb or whatever it was, so i think the partitions are intact. could this be a 'uselast24NAND' issue? i don't think i did that when i installed wp7, i couldn't remember when i was supposed to do that. ah geeeeeeeez

First check that WP7 still boots (if you've followed most of the tutorial for the old dual boot 1 sd card method you should be fine, otherwise you'll have to start over), and don't use 4ext nand recovery (doubt it'll run anyway), you need the 4ext SD version.
Just follow this , with the difference being having 3 partitions at the end ( FAT32|||EXT4|||WP7) then install via a SD ported recovery
thank you

ok, thanks hypoturtle. ok, i am going to take a little break, then find the sd version of 4ext, then i'm going to task29 this monster with hd2 toolkit and completely start over. i will update this thread with what happens and what i did. when i'm done i plan to make a complete step by step guide with links and all so there will be something with ALL the information and links in one place, placing all credit where it is due to the original developers. i am not a developer.
Yeah, that was the problem. You can't use NAND recoveries when on WP7 because they will format NAND and prepare partitions for Android, deleting WP7. For that you need SD Recovery ported by Xylo (available in NativeSD thread). After WP7 is installed, you don't even touch anything that's NAND related because it will break everything.
Check this video tut http://forum.xda-developers.com/showthread.php?t=944288
1. install wp7
2 make android partition as in vid.
You should have after the above.
<50% of sd card volume as FAT32 on first partition (primary)
>50% of volume unformatted (WP7) on second (primary)
Then you can create ext4 partition as second partition (also set as primary), I would use minitool again to shrink your FAT partition (but use 4ext recovery sd to format it see http://forum.xda-developers.com/showpost.php?p=31247925&postcount=3464 and the post before it)
So you have 3 partitions 1. fat android 2. ext4 3. wp7
I have not tried a smaller wp7 partition than 50%, don't know if it would work but 96edwy has suggested not to do this in vid.
thank you
thank you guys for your help. i have got it working and have made a step by step guide as i did it. just one problem, and i reaaaaallly hope its not a big problem. but in android it says no sd card. i need to know how to show whatever explorer program i use in android to look at the fat32 partition. anyone know?
i also need to know how to make wp7 see the fat32 partition that will have all the media files on it. anyone?
as soon as i get this information, i will post the guide. but i don't want to post it if there is something wrong (android and windows not reading the fat32 parition).
other than that both operating systems are still there and android is running from ext4 from folder nativesd!!!

well, i just checked it. i'm attaching the screenshot that shows the partitions. i'm a little scared to change the last one (the wp7 one) to primary for fear of messing it all up again. also, that shouldn't effect androids view of the fat32 which is set to primary right?

Can't imagine that would cause the issue, you have them layed out as Fat32 | EXT4 | Unallocated right? Have a look at df again see if vold/179:1 appears, have attached mine from PA

so thats how you see if it's called mmcblk0p2 or not.... finally. i never used it to set these up. is it too late? i don't even know how to get adb on my phone like you did, and i tried running adb shell from my computer but it keeps saying error: device not found.
how do i get it running on my phone as you did to check?

Screenshot is turned on in settings, system, power menu but yea it wouldn't work anyway, other than reformating the fat partition, i can think of much else you can try, i think you may have to tempt fate here and change the wp7 part to primary, can't recall if it messes anything up at this stage, i don't think so, as long as it doesn't require a format.

Hey Guys,
I have always used CWM Rom Manager but now it only bricks the phone when installed. "Encryption Error - Factory Reset", but that does not work, have to use AP Fastboot and reinstall JellyBean. Now that I have it up again, I want a recovery solution besides Titanium Backup that will backup the entire phone, like CWM did. So, I installed SafeStrap. (Rooted with Android 4.1.2)
Now I would like to format the internal SD Card to start fresh, but when I boot to recovery in SafeStrap, Wipe does not format the internal card. The terminal window in the Wipe action shows that it cannot find block device. But, the File Manager in recovery works just fine and the backup seemed successful. When I go to Advanced, Settings, there is one setting that cannot be unchecked. "Use rm -rf instead of Format?" No, I do not want to wipe the existing partition, I want to format the entire internal SD partition, so I do indeed want Format like CWM would do. Is there a way to uncheck this box and how do you do it?
SafeStrap does have a Terminal, use at your own risk. So do I need to Format the internal SD Card by command line? Command line Syntax, please? Since this is a deadly serious operation, I would hope to get an answer and someone to confirm it, if possible. Familiar with Linux so that might help.
Anyone can help, please?

Hello guys.
I was looking for a similar guide to link to my friend but didn't find anything, so I decided to write my own.
Personally I didn't find any good guide regarding partitioning from android itself, so I think it's also more unique guide because you can easily make your own partition layout without using PC at all.
Why I should use EXT4 instead of FAT/exFAT?
1. We're running Android, Android is based on Linux. EXT4 is native linux-proposed filesystem, while FAT/exFAT is not.
2. All our internal partitions (/efs /data /system /cache /preload) use ext4, natively.
3. CM has poor exfat support, while fat32 is not recommended for big file systems (over 2 GB) because it doesn't work well with them, thus microsoft implemented exfat.
4. EXT4 has better stability and performance, especially on Android devices, compared to exfat and fat.
When you should not use ext4 over fat/exfat?
- When you for whatever reason use your external sd card in windows environment physically. Android works in MTP mode, you'll use your ext4 external sd card the same way as you use internal one under windows. But if you for whatever reason puts your external sd card f.e. in usb adapter connected with windows then it won't work. So yeah, if you keep your external sd card in your phone then you're fine.
Expert Way (Requires fdisk/mke2fs utilities (busybox), works always):
1. Launch any terminal from Android environment (f.e. Android Terminal Emulator or adb shell through PC)
2. Make sure you have root (su command)
3. Make sure you have all required utilities. Type fdisk --help and mke2fs --help, both commands should print usage. If you get "command not found" then you don't have required utilities. Either install Busybox or CM-Based ROM with native busybox support (tested on ArchiDroid 2.X)
4. Unmount your external sd card (umount /storage/sdcard1)
5. Launch fdisk partitioning program on your external sd card (fdisk /dev/block/mmcblk1)
6. Destroy partition table (o), create new partition , make sure it's primary (p) and first one (1).
7. You can check if you're satisfied with your partition layout (p). When you're done exit and save changes (w)
8. Create ext4 filesystem on your partition (mke2fs -t ext4 /dev/block/mmcblk1p1)
9. Reboot
Android should automatically detect and mount external sd card in ext4 after reboot.
Here you can find a short movie which shows going through expert way recorded by me
Intermediate Way (Requires USB Adapter and some patience, should work like a charm):
1. You'd need USB Adapter or any device which can read micro sd cards on PC
2. Open any linux-supported partitioning program (f.e. partition magic, gparted, parted), it needs to support ext4.
3. Delete all partitions from your external SD Card (typically, one fat/exfat) and create one ext4 partition.
4. In case you'd also want hardswap create 2 partitions, one primary ext4 one and second primary swap one.
Newbie Way (Requires PhilZ Touch Recovery, may not work):
1. Launch PhilZ Touch Recovery
2. Select "Mounts & Storage" => "format /external_sd"
3. Select "ext4" as a filesystem
4. Please note that it can take some time. This way you should get running ext4 filesystem, but personally I didn't test this method, as I prefer more advanced ones .
This guide is more or less universal but I'm using sgs3 external sd card paths so I want to make sure nobody bricks other phones . Personally I suggest using expert way, as it's probably the easiest one.
Hit thanks if it helped, I hope it did .
@JustArchi thanks for the tutorial. Now for the sake of sdcard wearing. I would like to disable Journaling. How do you do that?
EDIT: also i noticed after formatting the externalsd card there is 3 GB occupied by nothing (?) This is normal?

tune2fs -O ^has_journal /dev/block/mmcblk1p1 should do the trick. You can put it in init.d if needed.
Also no, you should get full size of your sdcard. Are you sure that you've firstly destroyed partition table (o) and then created new full-size partition , as showed in the video?
You can use fdisk also to get information about your external sd card and find why is it smaller than it should be.
HI, My 64gb is two partitioned one hardswap and other primary.
Will I lose data on both partitions if I delete partition and format to EXT4?

You will lose data contained in the partition you are formatting. If you leave the other partitions untouched, you won't lose their data.

Just don't use (o), as it will destroy everything. Use an option to delete selected partitions (d, if I remember correctly) and create them through n.

Hi, thanks for te help, but now a have a 1 gb lost by system data or 0.8gb if i disable the journaling, that is right??? Thanks

It depends on your rom and also if you created ext4 properly. I've formatted my 2 GB SD Card to EXT4 and I got 1,80 GB free (yes with journaling). This is because 5%-10% is reserved for "super blocks". Read more -> http://en.wikipedia.org/wiki/Ext4

Hi Guys,
I am new fairly new to rooting and using terminal emulators.
I have a rooted samsung galaxy note 2 with superSU, busybox and shell terminal emulator. I verified fdisk and mke2fs
(fdisk --help and mke2fs --help) but then when I tried the command
"umount /storage/extSdCard"
I get the error message "Operation not permitted"
Can anyone tell me why this might be?
Thanks
/storage/extSdCard is the path to the external sdcard on my device.

I get the error message "Operation not permitted"
Can anyone tell me why this might be?
Thanks
/storage/extSdCard is the path to the external sdcard on my device.

Did you login as root before? (su)

I did not.
However, I did try again and got the sane result. I used these commands in shell terminal emulator:
su -
mount
umount /storage/extSdCard
result: "Failed: Operation not permitted"
I have verified root with root checker...and after typing the command "su -" I was prompted by supersu to "allow"
I believe this issue will likely be something simple that I am not aware of.
I have tried this on my galaxy note 2 and my tab3 8.0 with the same results.
I really appreciate any help offered.

Try to execute su -c "umount /storage/extSdCard"
It worked flawlessly in my case.
Thanks Archi. I was wandering around looking for a solution to the problem with my sd(I'm nooo0b if it goes about Linux/Android ). My Archidroid 2.3.3 did not recognized/mount my external card, so after following your instructions (using the terminal in android) now I can enjoy my 64gb sd card.. Great job!

Ok. That worked. Thanks.
I then tried (su -c "fdisk /dev/block/mmcblk1")
Then...press m for help...or pressing "o" gets me a syntax error.
I have attached a screenshot.
Thanks again

Okay, you're user, not root. This is a weird android shell, that's why.
Try to use "su -i" to get root shell, then use fdisk (without su).

Still didnt work. After typing "su -I" the next line still says "[email protected]:/$"
I was thinking I could try a reinstall of shell terminal emulator...or perhaps you could recommend a different one to use.
I will try again later tonight.
Thanks

Try android terminal emulator, you must gain root shell. Typically "su" command does that, "su -l" should as well.

Alright...typed su and gained root....got through ttothe last step.
I typed "mke2fs -t ext4 /dev/block/mmcblk1p1"
and the result was: "mke2fs: invalid option -- t"
I have trying to read about mke2fs and the -t option but no luck so far.
Thanks

Hello Archi and thanx for the tutorial
I followed all the steps, done it to the end, but after reboot I couldn't make any folder on SD card.
Card is recognized, formated as EXT4, but for some reason there is no way to put anything to it
Tried again with gparted, ended with same result.
Tried to change ownership, but that also didn't work out...
Now i reverted card to fat32...
Any idea what could be wrong?
btw, using NeatROM 4.4.2 with boeffla kernel and Philz 6.00.8
thanx in advance

Try using Minitool partition wizard, it helped me a lot of times.
When you open it it should show you all hdd (external, internal) partitions, and flash memory drives. Right click on your sd card and delete partition, and then create fat partition and click on apply changes. MAKE SURE you are deleting sdcard partition, not something else. Of course, by deleting partition you'll lose all data on the sdcard. Hope it helps...

Why not use the Window's command line disk repair utility "Diskpart".
If your sdcard cannot be formatted normally then you need to perform
"Delete/Create" partition in diskpart before you can format it.
In disk part there are a lot of options you can choose from including
"Delete partition", "Create partition"... Delete and Create partition
is what you need to do before you can successfully format it.
Just click on RUN in your start menu and type "CMD" and press "enter"
then type "diskpart" and press "enter" again.
I have done this many times with great success.
Good luck!

If you want a list with examples of how to use diskpart
then click on this link: http://technet.microsoft.com/en-us/library/cc770877.aspx
You will find it very helpful, it gives all commands and examples of the
command line options.
At the command prompt just type "diskpart", you can type "?" and "Help"
in diskpart itself to give you examples of the commands.
Good luck!
