First I couldn't find e2fsprogs. Turns out they are in Chinook repository, not Diablo.

I removed gparted-hack, with the thought that I'd install e2fsprogs first, then I changed my mind and decided I wanted to have gparted-hack installed, just to see what happened when I tried to install e2fsprogs after gparted-hack.

That's when I found that my mmc cards were no longer visible! I must have to reboot to see them again....?

So I downloaded the .deb again, this time into my Documents folder, and installed it.

Then I added the Chinook repository and installed e2fsprogs.

Ran Gparted. Usual error (with maemo gparted only) about memory card being corrupted.

Hooray, all ! are gone. That was it; I didn't have e2fsprogs installed. Add that to dependencies.

EDIT: Why can't my tablet find e2fsprogs for diablo, when it is right here? Why does it not show up until I add chinook?

EDIT2: Aha, it ISN'T there, only the diff.gz and .dsc files are there, no .deb!
