Yes, it's builtin to ext2/ext3. There exists two tuneable parameters (use tune2fs): max-mount-counts # -c option interval-between-checks # -i option These are examined whenever it gets mounted. I don't know what the defaults are, I've seen them displayed when tripped in the past though. I think there isn't such a mechanism for reiserfs v3. I don't know about others such as xfs. The other parameter to be aware of is the sixth field (fs_passno) in the fstab line (if you're using an fstab entry). If it's set to 0 or not present, fsck will not do any checks when mounting at boot--though this probably does not affect your setup since you're dealing with removeable devices. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
