I noticed in your article about making DOS-less disks that you shortened the catalog so as to make some of the track 17 sectors available.  That's nice, but DOS will not allocate sectors out of track 17 unless a small patch is made to the allocation routine.

Change the byte at $B292 from $69 to $A9, and those sectors your freed will be usable.

Thanks, Larry!  You are exactly right.  Evidently FID uses a different scheme for allocation, because when I filled up my DOS-less disk my sectors in track 17 were used.  If I had used LOAD-SAVE to move the files, those sectors would have not been found.  From now on I am going to use your patch.
