Cool, just did a fsck on dd-ed images via PartedMagic @ Virtualbox -> T1/ext SD
fsck works directly on image files. No need to fiddle with loop back devices...
If I dump them back, they're fixed...
But first I will enlarge data partition to 512MB to get rid of Link2SD... Let's see if I get internal flash repartitioned via fdisk...
The steps in the wiki are incomplete!! They'll break the extended partition & internal sdcard...
