yesterday before i went to sleep i thought let me try ckfs.vfat -wa and what did i see. My flash 32 gb doesnt pass the block test. it stops at 16386 and wont continue. This looks to me a very good proof to nokia that the phone does have troubles...

it came too with the bootsector differs from the one in the backup.

and after all i got an input output error when i have troubles. after reboot the flash 32 gb is online again. but still didnt pass byond block 16386.
