It happens that no matter what I do (and I've tried almost everything) it formats but no matter what I do when I record a large file (2GBytes) it generates file system inconsistencies. First I thought that perhaps the device was defective. But when I try to write and read it, everything seems to be OK. It even passes badblock -w ... Any suggestions on what may be wrong?
