Exclamation i9100 problems - FORMAT PRELOAD or VIPE FACTORY RESET

Hi lads, i have huge problem with my i9100, so i wanna make some steps to make it better.

I have installed CM11 with CWM v6.0.4.7
When i try to make - wipe data factory-reset, CWM give me error E:unknown volume for path [/sd-ext]
When i try to format /preload CWM give me error E:format_volume: make_extf4fs failed on /dev/block/mmcblk0p12 Error formatting /preload!

Something is not right.
I need to clear everything and start from beginning, I was thinking about installing a new krenel, then install some three file rom by ODIN.

What do you think ?
What should i do ?

Thanks in advence ..
