Error when doing factory reset in CWM

when flashing roms, and doing WIPE DATA/FACTORY RESET option in clockworkmod v4 or v5 it gives a error E:format_volume make_extf4fs failed on /dev/block/mmcblk0p2
what is this? It looks like it still wipes data though, also it gives similar error when you go to mount and storage menu and choose the format /sd-ext option ..... looks like the sd-ext is messed up....
how can I solve this???
You need to format your SD card using CWM. It is missing the second (EXT) partition...
if u format u lose everything
the mount things isnt a prob

Close Please. Solved

Hello guys,
I have a very strange problem that noone else has because i cant find anything about it on the net.
I have a Galaxy s3 with cyanogenmod 10.2 and boeffla 2.1 stabe using twrp as recovery. I´ve set up my system and made a backup of everything. then i´ve wanted to check if the restore is working so i restored my backup. after a reboot my entyre phone was set to factory state. happened 2 times . cyanogenmod was still installed but i had to configure the entire system again. after downloading all apps i decided to install cwm instead of twrp using cwm 6.0.4.5 touch for i9300 flashing via odin 1.85. everything worked fine and i booted into recovery to make a backup. cwm then says: Error cant mount /system so i tried to mount the system via the storage option. still says cant mount /system. then i rebooted my phone and again everything was gone... im really angry because whats the point of using a backup and then everything is gonna be erased.
i hope someone can help me with this. i also would erase everything and start from zero so that everything works.
Edit:
manual factory reset shows this:
formatting data
Error mounting /data.
Error mounting /sdcard/ . android_secure!
Skipping Format
formatting cache is working
cant format sd card.
&
Cant download apps from google play because of server problems...
show log:
mount: mounting /dev/block/mmcb1k0p16 on/data failed: no such file or directory
W: failed to mount /dev/blockmmcb1k0p16 (file exist)
cant wipe dalvik cache
!!!phone gets resetted everytime after cwm says error cant mount /system!!!
regards
Can be closed
I´ve installed original Samsung firmware and then CWM + CM10.2 + Boeffla 2.1 again and now CWM can mount everything and the Backup also works. maybe Twrp ****ed something up. i dont know.
regards

[HELP]Moto E TWRP error in filesystem and Boot-loop.

Im using Moto E 1st generation, Bootloader unlocked with TWRP custom recovery. I was using custom rom Marshmallow by Temasek and I thought to change the rom. Recently, I upgraded TWRP to 3.0.2-0.
I have wiped system, dalvik, internal storage, cache and data everything went smoothly.
when i tried to install Rom zip i encounter and error that causing boot loop.
HTML:
mount: failed to mount /dev/block/platform/msm_sdcc.1/by-name system at /system: invalid argument
unmount of /system failed : no such volume
Patching system image unconditionally ...
flashing Supersu..
scripting succeed result was []
update partition details
...done
when i reboot, my phone goes in boot loop.
i tried with repair or change file system but still the error is same
my file system and format
/system ext4
/Data ext4
/cache ext4
Please Help to recover my mobile thank you...
flash the stock firmware, some times it fix this issues.
flash the stock firmware without flashing the recovery partition, and flash again twrp to avoid any issue, then flash temasek

TWRP cant mount /system

Booting into TWRP give me an error "Unable to unmount /system, partition or resource busy" and subsequently, i can't flash any GSIs to the system partition, i get the error "Unable to install images to file systems". It is possible to boot into fastboot and flash however.
This seems to be an issue regarding to TWRP mounting /system, iv'e read up a bit on it, and it seems that a data wipe in TWRP should fix it?
i
Im on TWRP 3.2.1 for the H9

TWRP on Swift 2x: Failed to mount '/data' (Invalid Argument)

Hi all.
I'm trying to make a last backup of the stock Android of my Swift 2x before flashing LineageOS. But TWRP (version 3.3.0-0) Seems unable to use the /data partition. I got various messages like:
Could not mount /data and unable to find crypto footer.
Failed to mount '/data' (Invalid Argument)
I tried to format the partition: Wipe -> advanced wipe -> repair or change filesystem -> change filesystem -> ext4 but it didn't change anything.
What's wrong? What can I do?
Thanks a lot for any hint.
bumping this thread as I also ran into this issue.
When using TWRP, the data and system partitions can't be mounted. they also show up as being 0mb in size.
Because of this, no backups can be made and a full system wipe also yields errors.
What I did was change the filesystem to ext2 and then change it back again to ext4.
Doing this at least allowed me to flash crdroid, but making backups still doesn't work.
Whenever i go into TWRP again, it's the same thing again: unable to mount and partitions show up as 0 mb in size.
Anyone know what's causing this?
Wileyfox encrypts there data when you factory reset your device or after youve rooted your device .To get around this you need to do a factory reset using stock recovery once thats done then turn off the device. Then using minimum adb and fastboot type (fastboot boot twrp.img) that will boot your already installed twrp now erase data internal storage etc you'll notice you can finally delete stock os youll see internal storage is showing mbs available again etc worked for me perfectly.
