Btw by cosmic rays, do you mean solar flares in particular? I do not know much about astronomy but I heard those can cause problems with electronics if they are very intense.

I'm not good at astronomy either... But I mean any kind of energetic particles that would come from space and cause small bugs by interfering with the hardware. I don't know much about that, but I know it happens, even though it's quite rare... And as I said, the guy that got these errors really knew his field. But I'm not saying this must have been what happened to your database...
I've been following nspire hacking for about two years now, and I was glad to read about the first ndless. I do need my CAS for other things than playing though, so I can't stick to v1.1... Ndless 1.7 is going to be great :-)

the filesystem got somewhat totally destroyed, I don't know how it is even possible. e2fsck found so many corruptions that I thought the disk was filled with garbage, such as if some block (and all the following) was not properly aligned.

I've heard of that before. From someone that was running a room with many servers, and approximately once every three years a whole row of blocks would get corrupted on one of those. He eventually figured out what was happening, something about the read/write system. For what I understood, when something was read, it had to be rewritten at some point, and sometimes it failed attempting to do so, leaving a row of corrupted bytes. He figured out that it was caused by cosmic rays... That sounds unbelievable like that, but he definitely knew what he was talking about.
