When I modified the boot sector of an ST disk, as instructed a while back
(using Norton's 4.0 on a PS/2 Model 50 running PC-DOC 3.30),  the PC could
dir the disk fine, but any files we tried to copy off would be truncated.
Could this be related in any way?  I was hoping to not have to copy 30
disks to IBM format to get them on a BBS run on an IBM... it would take
weeks!
