xperia S cache format failed on block 13

Hello all,
First some background
as you can tell i have an xperia s. I had initially rooted it in .45, installed CWM, installed .55 system and CWM again, and had a perfectly healthy tool on my hands. A week ago i realized it had suddenly started to eat up the battery in half a day. I uninstalled everything i could think of, and nothing happened. So i though of going back to a previous CWM backup.
That proved impossible since the backup sequence always stopped at a formatting error. After a dozen attempts i lost my patience and used flashtool to install and root .45. Then CWM, then OTA to .55, and then CWM again (it was lost after OTA update to .55).
Took me about a day to put everything back.
That was yesterday.
Today i tried to install the camera mod from xperia V (had it before and truly the focusing is faster, cannot vouch for anything else though)
And there it was:
Instructions for installing the zip require to wipe cache first.
Through CWM when i tried to wipe cache, both ways available, i always get the same error
make_extf4fs failed on /dev/block/mmcblk0p13
I have seen that before on my phone but everything works OK in normal mode. Only time problems arise is when i need CWM...
I have also seen it reported in xda but nobody posted a solution.
Any thoughts?
I cannot take it back as defective either, because it works ok:silly:

I decided to take it a step further.
Went into CWM and chose wipe data/factory reset.
Here is the log

can u connect it to fastboot?
if u yes, from fastboot: fastboot erase cache. fastboot format cache. i think that flashing ftf full wipe can fix that too.

I am having this issue even after multiple(2-3) full wipes.
Let me be clear about that.
First time i encountered the situation i though it was just a glitch. So i went all out and erased everything. Reinstalled .45 , rooted, then OTA-ed to .55, then installed CWM (i actually installed it first at .45 but during the update to .55 it was lost, so i installed it again.) Problem insisted , so i re-did it all a couple of times until i run out of time to keep installing everything!!!
Now, as for the "manual" format you are referring to. How do we do that?
Can we do that through flash tool?
I was thinking of connecting the phone to the flashtool in flashmode and choosing only wipe cache.
But in order to do that i first have to choose an ftf and i was worried that i might erase everything again. I absolutely have no time to be installing everything again...!!!

I never tried but i think i can connect it to fastboot. But i am not much aware of fastboot process. SO i am hesitating to flash it..Though i'll give a try n will let you know the results.

Don't worry my friend. The phone does everything it is supposed to do.
I have tested it as hard as i can but no error pops up during any operations.
Just when you format cache through CWM

Same problems here. error at block 13. Is there any fix yet? TIA
edit: So block 12 is for /system and block 13 for /cache I think and block 14 is for /data or sdcard. errors on all of that.
edit again today: Found the fix HERE. by just installing via fastboot ics17.elf (Advance Stock ICS Kernel)

I have the same errors again and again. Now each time i want to change the rom I have to flash Sony .45 rom, upgrade to .55 then root and flash CWM. It's either that or get stuck in à bootloop.
I've sent full error log on another thread.

That's true. My bootloader is locked as well

isn't there way to track the problem and see what causes theses errors. apprently there aret terribly specific to some phones or some roms, stock or custom.
there should be a way to make a log of what's going on and have a dev help us with this.
here's the link i posted my error log with cwm :

According to Arakmar, the CWM formatting issue was fixed by updating the MMC storage driver in the kernel. As far as I know, drivers are a part of the kernel source which is then compiled to give us the zImage. Compiled zImage+ramdisk=custom kernel
As custom zImage cannot be installed on locked bootloader, this method won't work. There must be some other workaround to this problem..

that's this workaround we're trying to find. i've been told that a recent install of busybox should fix the problem but AFAIK it does'nt work on my phone.
Edit : problem is still here. I've tried to change the rom i'm using today, first, by flashing CWM v2, but get the same errors.
Had to flash .45 firmware, upgrade to .55 by sony upgrade, root, flash CWM and then wipe and install rom.

Plz help...this is a serious issue 4 me...seen different thread,,, but no sol.

I had those formatting errors sometimes, too. For me, it was solved by formatting /sdcard (first backing it up), after that, I could format other areas, too.

Same for me too. My XS also needed a motherboard replacement. For everyone, if possible then just unlock your boot loader and flash a kernel in which this bug has been fixed. Hopefully in the JB update Sony will update the mmc driver.

Deleting 20 giga and restoring it is certainly not my idea of a quick backup and restore .
For the time it would take to copy 20 giga back and forth i could have installed everything again by hand..
Good info though.
I have noticed that formatting /data also lets us use it without the block errors

As usual I recommend to begin from scratch by flashing 3-Parted GB FW....(with re-partition activated)
This is the "swiss knife" for all major problems regarding FW etc...

Note that you choose the correct GB(!) FW for your Phone.
Let your Phone boot completely after this...
After this JB again - and if you like CM

I hope I get a solution on fixing this problem.

Which recovery and version are you using?
Is the device currently rooted?
Were ANY other modifications made to the device prior to this occurring?

Hey thanks for your reply!
My device is rooted and unlocked.
I'm not really sure about this but I used wugfresh's root toolkit to root but it failed, so then I used cf-autoroot by chainfire.

Sorry to say, but I had the same sort of issue with my Huewai Ascend P1 LTE as one of the partitions wouldn't unmount. The device still boots but the wifi is broken. It's pretty much a paper weight now. :crying:
Its one of the few things which puts me off rooting. If I dont need to root, I dont.

Thanks for your reply! I think I need root I'm a type of a guy who can't live without root! Thanks for helping though!
