Hi all, I've read somewhere that the suggested mount option for USB key with FAT filesystem is "-o flush" instead of "-o sync" (if you want to remove the key safely, without executing umount or sync). sync option is quite dangerous (and slow) for flash file-systems since it does an aggressive flushing on the FAT, which can damage the flash. Anyway with flush option (kernel 2.6.32), I experienced the following: - if I create or modify a file on the key, the fs is sync'ed immediately so I can pull out the key immediately with no side effects - but if I only create a directory and anything else, the "flush" is not executed immediately, so if I pull out the key, the directory just created disappear (which is not what I would expect). Can someone please tell me if this is the right behaviour or am I missing something. Thanks Best regards Luca Ellero
