Hello, I need a flight-control computer, that can be turned off while it is writing log files to the SD card without having any problems when turning it on again. Can this work with the default FAT file system and Ubuntu? Would that work better with ext4? Regards: Uwe Fechner
The key is whether you mean a graceful controlled shutdown or an abrupt removal of power etc. The former and it doesn't matter which file system you have really. I suspect you mean the latter, whichever file system you choose you'd need to turn all caching off and do immediate writes with Journaling - several options exist (vanilla FAT isn't one of them).
Hi, I found out the default Linux image is using ext3, and not FAT. So I assume that a hard shutdown is safe, without causing long delays during the next boot. This is nice! Uwe
