Ooops, looks like you are right.
In hdbdos.asm, there is
****************************************
* SCSI/IDE/DW START HERE
****************************************

then look for

                IFDEF     IDE
* SETUP - Setup the Command Packet

All the read/write and command setups follow for IDE. If writes work on the 
hardware but reads fail, then there ought to be a timing difference or incorrect 
command setup in this section.
