This is really a Linux question, but since it is specifically about embedded systems, I'm hoping this group is a good place to ask.
My application is based on an Atom, with a small USB flash drive (SLC) for its storage. I'm trying to decide what file system to use. The application doesn't do a lot of file accesses, and of course I'll mount the partition(s) with "noatime" since I don't care about recording access times. But I'm concerned that if someone yanks the plug, rather than pushing the button for an orderly shutdown, the next boot will do a long "fsck", and the user will think the system is broken. So I guess the questions are these: Are ext2, ext3 and ext4 all equally likely to need to do an "fsck" after a disorderly shutdown? Do they typically take different amounts of time to do an "fsck"? Or is the journaling of ext3 and ext4 something that should be avoided on a flash drive at all costs, even though my app won't be doing much file access? Also, my app stores its own data in a directory tree of typically a few hundred small files. Would it be a win or a lose to break this off into a separate small partition? I was actually thinking of making this a FAT32 partition, so that I could yank the drive and access those files in any other machine. Any insights would be appreciated. -- Ciao, Paul D.
