In my program which diddles with the floppy disk, I do the following


   DoIO( ETD_WRITE) /* To write out a track of data, in sectors */
   DoIO( ETD_READ) /* To verify it made it to disk okay */

The question being, do I need an ETD_UPDATE in between the
write and the read, to force the READ to actually read from the
disk, and not just from a track buffer in memory?
