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

hey, I installed the CM7 today by using the clockworkmod 0.8 (I used the VEgan 5.11 before )
I wipe cache partition, wipe data, wipe, wipe Dalvik Cache
but when I wipe Dalvik Cache, there is a error: can't mount dev/block/mmcblk0p2
anyway, I install the CM7 successfully... but I am a little worried about that erro...
so why this error appear? what is that mean?
do I need to fix this error and then reinstall the CM7?
sorry for so much naive question! thanks!
savage0,
I've read two or three explanations for why that
error comes up -- but I really don't know why.
I do know that a pile of folks have been getting
that message almost since the G-Tablet came
out and I have never heard of it meaning anything
significant -- or anyone having problems as a
result.
Forget it is my advice.

Exactly. Had that issue since my first flash and nothing fixes it. On the good side, like the Rev says, it has no known meaning or consequence.

The correct error message actually is:
Code:
E:Can't mount /dev/block/mmcblk2p2
(File exists)
As butchconner said, it's a harmless error message. It just means that
a) You don't have an external SD card in the SD card slot, or
b) If you do have one, it does not have a second partition on it. Most likely, you have a SD card with a single VFAT partition.
When you select the "Wipe Dalvik Cache" option, CWM does, basically, this:
1. Mounts the /data partition. This, on the gTablet, is the second partition (Linux ext3 type) on the internal SD card, /dev/block/mmcblk3.
2. Mounts the /sd-ext partition. This is the second partition (generally of Linux ext3 type) on the external SD card, /dev/block/mmcblk2.
3. Mounts the /cache partition. This is a yaffs2 filesystem (on /dev/block/mtdblock4) on the in-built NAND flash chip.
4. Prints a "Confirm wipe?" message and a "Yes - Wipe Dalvik Cache" menu.
5. Removes the entire /data/dalvik-cache directory tree.
6. Removes the entire /cache/dalvik-cache directory tree.
7. Removes the entire /sd-ext/dalvik-cache directory tree.
The error message you noticed comes at step 2 because there is no external SD card, or, the external SD card does not have 2 partitions on it.
The second line, "(File exists)", is the left-over result of a mkdir() system call used to create the mount-point directory which already exists.
If you can read C code and wish to look at this further, look at the show_advanced_menu() function here:
https://github.com/CyanogenMod/android_bootable_recovery/blob/gingerbread/extendedcommands.c
The link is for a newer version of CWM, so the error message is different.
Cheers!
sorry for posting here.. tryed to search but no luck..

I am having the same issue and cannot get my nook to get beyond the CWM screen. The question: Has a solution to this been identified?
Thanks.
When you boot into recovery try wiping data to factory reset, wipe cache and dalvik cache. Then install the ROM from the SD card afterwards.
Sent from my NookTablet with CM10.1
can anyone help me?

it's fix, just re-partition your sdcard on cwm.
sorry for bothering.
I have Samsung Galaxy y s5360.
I have installed CWM and Custom Rom of Cynagenmod on it.
When i go to wipedata/factory reset my Phone I face the Following Error
Formatting /sd-ext...
E:format_volume: make_extf4fs failed on /dev/block/mmcblk0p2
A samilar error occurs when i try to restore my Orignal OS from recovery manager.
E:format_volume: make_extf4fs failed on /dev/block/stl19
What should I do?
That's just the error that CWM gives when trying to format a partition that your phone does not have. It does not indicate an issue with the internal storage not being wiped. However, the factory data reset in CWM does not wipe /data/media where stuff like pictures, some types of app data, your download folder, and others are located on the internal storage part that your phone considers the "sd card" not to be confused with the external SD card. If you want to wipe that to perform a full wipe of everything in CWM you will have to format the internal storage in the Mounts option from the main page of CWM.
