sorry for didn't give any reports yet... (still exhausted from new year eve barbeque party)
ok, but now here some reports for what i have did with cwm 22.214.171.124 so far:
> flashing rom (with sd-ext format process included) still false reformatting my ext4, on my case to ext3 (tried by flashing cm7.1 rc3)
> doing wipe/factory reset also still false reformating ext4, on my case to ext3
> formatting sd-ext, formated my ext4 to ext3
> try some cwm-recovery restore/advance restore sd-ext, also formated ext4 to ext3
> doing backup & all the things that nothing to do with cwm sd-ext reformatted proccess seems work properly & have no problem on me
my conclusions so far it still have issues with anything to do with cwm-reformatting sd-ext process...
