Hi everyone
I've taken some time trying to solve this myself and checked the forums here pretty carefully, but if there is a thread already answering this I apologise.
I have a 32 Gb Verbatim USB Flash drive that I want to use with a Raspberry Pi as a datalogger. Since the Pi is weedy I'm using my Ubuntu VM to format it - but no matter what I do I get superblock errors. Gparted will happily create a new a new partition table and then format the unallocated space as EXT4 - and then when it rescans for devices it puts an (i) up against my new partition and tells me that the "journal superblock magic number is invalid".
I mooched about a bit looking at other people who have had similar issues - e2fsck doesn't seem to help.
The drive itself is relatively new, decent brand - I don't suspect a hardware error just yet, not least because I managed to get good old ******* to format the drive as FAT32 and it survived a pretty intense read / write speed test.
Any help anyone can offer would be gratefully received - I don't know enough about filesystem architectures (least of all EXT4) to make any properly considered progress.
Many thanks
Stefan
