I have MTOOLS version 1.6.2 (Jul 5 89) and it corrupts files when copying
to/from low density (770 K) 3.5" floppy disks. It works fine with the high
density 3.5" floppy disks (1.44 M). I have compiled this with/without the
optimization and on both a Sparc 1 with OS 4.1.0 and an IPC with OS 4.1.1.
Does anyone know of a more recent version/patch/fix than 1.6.2 (Jul 5 89)?
[[Ed's Note: You may want to verify that the patches on titan.rice.edu
have been installed in your code. I am not 100% certain what the latest
version is - there are a couple of readers working on tracking that down
even as we speak. I *do* know that one of the problems fixed by the
patches on titan involved problems writing low density disks. -bdg]]

Is this actually a bug with mtools, or SunOS ? I have a problem with mtools on a 3/80 running 4.1.0. Although it works fine with 1.44Mb disks, on 720k it keeps producing "missing header" errors. But then does anything using 720k disks on the 3/80. Sun says that this is a known bug, but bearing in mind their priorities, your guess is as good as mine when it will be fixed. Just a thought ....
