That is a good idea. I do see a message in the syslog about mmcblk2p10 being unchecked when mounted. From post #25 I got the proper statically linked version, and it checked the partition. Fortunately it had no complaints.
I wonder if anything changed between firmware 1.00.00 and 1.00.04, since I vaguely seem to recall that I was able to run a dynamically linked e2fsck before (with 1.00.00), the one linked from post #1. (But maybe I remember wrong)
