Two things:
1. The 256mb rootfs is formatted to Ubifs. This filesystem does not need a fsck tool, and seems to be /very/ resilliant when it comes to corruption - Seriously, I haven't ever had it fail.
The optfs, on the other hand, is just ext3, and it /is/ fairly succeptable to corruption. Maemo will attempt to fsck it upon boot, but it doesn't always work, resulting in the "five dots" reboot loop.
Mydocs and the SD card aren't needed for boot.

Now, Backupmenu only uses files on the rootfs, so it's a lot more resilliant to optfs corruption: Wipe the optfs, it'll still work.


2. Fusi, yes, there's a magnetic sensor. When the back cover is removed, the SD card is unmounted(so it's safe to remove).
