In addition to making sure your buffer does not span a 64k absolute memory
boundary,  you should make your read and write request size an integral
multiple of your track size.  For the RLL drive you mentioned, I believe
the track size is 27 sectors (13.5k) so try reading & writing 54K
at a time instead of 64K at a time to avoid additional deblocking from
partial track read/writes.
