[Q]Motorola Defy(MB525)/data and /cache partition problem (corrupted?)
I found my data and cache partition corrupted, and i dont know why.
I don't know anyway to fix it but do SBF flash (so far I am doing the THIRD SBF flash today, really frustrating)
 why i think data and cache partition corrupted:
1. I couldn't mount data and cache and psd partition in recovery, but i can mount sdcard (and can't unmount system partition, is it supposed that system can't be unmounted?)
2. when i booted up the system(Kayant's AOKP), the size of internal memory is 0.0B, as shown in the settings->storage
Is there any to fix without doing SBF flash?
How to prevent it/any precaution so that the partition wont mess up? (I probably did some wrong thats why the partition was messed up, but I have no idea what I had done wrong)
here is what i did:
I had had this problem before so I do a SBF flash and the problem is gone.(I installed Kayant's AOKP rom -4.1jb)
Yesterday I decided to flash another rom (that was Quarx's cm10.1 rom) i did a nandroid backup first, then installed the rom and installed some apps, after that I installed Kayant's Slim rom(from the new aokp paradise), i found some bug and at last decide to return to Kayant's AOKP rom. I installed the 2nd Init boot menu(coz i did the nandroid backup with CWMrecovery, not TWRP), and problems came while restoring it. It failed to restore /data partition, I tried more times but couldn't fix this. So at last I turned to SBF flashing.
I flashed and rooted it with SuperOneClick and installed 2nd Init boot menu then install the AOKP rom(didn't restore the nandroid this time) then factory reset-ed it with stock recovery, and I found the /data and /cache partition messed up again(obviously the partition isn't messed up right after SBF flashing because i can install the 2nd Init app).
Now I am doing the third SBF flash.
