    One problem you might be having is that PC-DOS seems to store 
information internally.  The first time I do a dir on my st238 (30mb)
drives it lists all the files in that dir, then spins the disk for a
while to get the remaining space. (prints the listing, but stops at
the "available" flag and spins until it counts bits I guess).  After
that, it knows so it doesn't rescan at that point.

 All of this is conjecture based on observed delays and in no way
reflects any other information. (In other words, it's all guess work.)
