What's the console command for deleting the contents of the ext partition? (\system\sdcard)
Can you reformat the ext partition from the recovery console?
Thanks
If you want to delete the contents of your /sdcard then in recovery console mount /sdcard then rm /sdcard/* should do it for your fat32. To clear your ext3 do in recovery console mke2fs -j /dev/block/mmcblk0p2
hey guys, when i try and update my recovery through terminal emulator I get an error
after the line
"mount -a"
i get:
mount: mounting /dev/block/mmcblk0p2 on /system/sd failed: No such file or directory
mount: mounting /system/modules/modules.sqf on /system/modules failed: No such file or directory
mount: mounting /system/xbin/xbin.sqf on /system/xbin failed: No such file or directory
What is wrong here? it seems as if my sd card is missing files?! Can someone give me the files i am missing or would an sd card reformat fix it?

The first error means you don't have an ext2/3/4 partition and you should be fine
The second and third are common errors and don't really mean anything
Just continue flashing the recovery
alright cool, i have now got the new amon recovery!
Hey,
I like to mount my external SD Card as ext3 to support large files. The SD Card is formatted with ext3 but now Android shows only an empty folder.
So i tried to remount the SD:
Code:
mount -o rw,remount -t ext3 /dev/block/vold/197:33 /mnt/sdcard/externald_sd
But it doesnt use something... Does anybody has an idea? Some Example or sthing else?

u need a kernel that supports ext3. u can ask one of the guys compiling at the moment if they have time to add an ext3 module for u.
May be a stupid question:
would ext4 work instead? I thought the system partition would use this FS.
filesystem is already ext4

well the system uses ext4 so it should work, but i'm not sure what u're trying to achieve. i use a 16 gb class 10 formatted fat32

He's talking about formatting external sd-card
When I get him right, he has a file that exceeds the 4GB FAT32 limit.
So he looks for an alternative to FAT32, which might be some kind of ext*-FS.
wintel your right!
In the Android-Hilfe Forum someone said the system expect first an vfat partition and then the ext. I think thats wrong cause its not working but somehow it has to go.
Hmm should I write these mount command I postet in the init.rc? Or something else. Would be very nice if you post your ideas!
Thanks
init.rc+ ext3 module/object included in kernel
Hmm okay thats good but how do I use them? So I can read and write to my external sd card with an ext3 or ext2 partition.
Thanks
Come on guys where are the great developers?!
Ok I did a test with busybox inbuilt mount, but I tried only with an image.
Not with a real SD card! This worked for me:
On a linux box:
# dd if=/dev/zero of=/tmp/image bs=1M count=1k
# mkfs.ext4 /tmp/image
Copy file to your phone. Then:
On the phone with terminal:
# mkdir /sdcard/mmnt
# busybox mount -o loop /sdcard/image /sdcard/mmnt
To unmount:
# busybox umount -l /sdcard/mmnt
Anybody tried that?
If I understand u right u puting an image file (ext3/4) on the sd and mount that as a virtual disk. Wouldn't the image file be bound to the same restrictoins as other content on a fat32 file system? Like the 4 gig limit!
YOU WILL LOSE ALL DATA ON YOUR SDCARD IF YOUR FDISK
BACKUP WHATEVER IS ON THERE FIRST!!!
YOU'VE BEEN WARNED
using a photon 4g but....
what i did was get an external sdcard reader writer...
(used ubuntu) and let it mount
fdisk device and DELETE ALL PARTITIONS
write
fdisk again
create a linux primary type 83
type mount and grab the /dev/sdcX value (it was /dev/sdc1 for me)
umount that
then
mkfs.ext3 /dev/sdcX ... ( heres the thing though with cyanogen mod 7 kernel 2.6.32.9 SMP PREEMPT)
had to reboot twice for it to be seen in file manager...
its buggy but it does work for the most part
Reviving an old thread, but I just found that I can format a MicroSD under NTFS and it will work with Paragon's NTFS module. At the very least, my phone will mount the drive. I partitioned and formatted it with ext4 on my Linux machine and it didn't recognize it, but I did have it use the GUID partition table. Hoping to be able to load up some videos to take with me.

The problem is with the shell interpreting the special character ":"
To make it work, first create a symlink to the device node:
Code:
ln -s /dev/block/vold/197\:17 /dev/sd2
Then mount it:
Code:
busybox mount /dev/sd2 /mnt/tmp
Code:
sh-4.1# ls -l /dev/sd2
lrwxrwxrwx root root 2013-11-16 14:45 sd2 -> /dev/block/vold/179:17
sh-4.1# mount|grep sd2
/dev/sd2 /mnt/tmp ext4 rw,relatime,user_xattr,acl,barrier=1,data=ordered 0 0

An improvement in technique to mount ext formatted SDcard:
1) be root and open terminal
2) insert the card
3) see the block device and partition names from dmesg
4) mount device to location of choice (create the directory if needed)
Below is an example of an SD card with one ext4 partition on it
Code:
bash-4.1# dmesg | tail | grep mmc
<6>[20230.719541] mmc1: new high speed SDHC card at address 0007
<6>[20230.722803] mmcblk1: mmc1:0007 SD32G 29.3 GiB (ro)
<6>[20230.728352] mmcblk1: p1
bash-4.1# busybox mount /dev/block/mmcblk1p1 /data/mnt/sdcard2

Would this work just the same way with i9000?
After this, no more access to the extSD by the Windows PC but only with Ubuntu, right?

Since it's generic Linux kernel and busybox functionality it should work on any 'droid. The SDcard device name might be different than in the above example - you will see the correct device and partition names after you insert SDcard and run `dmesg | tail` on the tablet or phone.
(of course your device must be rooted and have busybox...)
Typically Windows is engineered not to recognise anything that does not come from Microsoft, so you will not be able to mount the Linux partition via Windows.
hi
I would like to mount an ext4 partition of the SD. If I mount it with a terminal emulator, I can only access it with the terminal-app. Is there a way around this?
Hi:
I've messed up my Note 9 pretty bad, such that no partitions mount in TWRP except cache - I'll need to do a data wipe, but I need to save data that I have in the Internal SD.
I've discovered via fdisk in TWRP that the media part - the Internal SD is partition sda25 - however can
t mount it in the terminal through a simple: mount /dev/block/sda25 /mnt
I get an error: mount failed: Invalid argument
I've tried: mount -t sdcardfs /dev/block/sda25 /mnt
This gives me also an error: mount failed: Not a directory
Mounting with -t vfat or exfat gives the Invalid argument error.
Anyone can help me with how to mount it, so that I may copy data off of it manually? I don't want to lose it. Many thanks.

cant you simply wipe the affected partitions(except data of course)? then flash a rom?
have you tried;
mount /sys/block/sda25 /mydata
or
mount /dev/block/sda25 /mydata
or
adb
mount -o rw /dev/block/sda25/data /mydata
in both cases /mydata is just the mount point so I believe it can simply be called what ever you want including just /data
have you read:

edit:
by any chance when you first flashed twrp, did you forget to format data?
if yes then flash back stock AP file(original phone's firmware) in Odin AP slot only and you should be good to go.( you shouldn't loose any files in internal storage)
