The "disk" column tries to count the number of entries in the disk
status message, and decides how many graphs to include based on that.
If you do a "view source" on the disk status webpage, you'll see a
"<!-- linecount:N -->" string showing what count it arrived at.

The "trends" column looks at what disk-RRD files exist; if you have some
filesystems that are not always reported, then there will be RRD-files
for these, but they will be missing from the disk status message - 
hence the difference.
