resize2fs: Bad magic number in super-block while trying to open /dev/sdc6
Couldn't find valid filesystem superblock.
Ok, not quite as planned. Parted also can't seem to cope with the funky overlapping first partition. So I'm trying fdisk. I have a dump of /mnt/storage, so I made a new ext3fs and restored the files.
Reassemble partly, power up and hold breath...
