I was on Compuserve last night in the Windows Forum and read that Microsoft
and OnTrack came up with a solution.  It was a simple system.ini setting
in the [386Enhanced] section... I'll pull off the article, but for now here's
and excerpt from system3.txt file that should have been copied to your
Windows directory during installation:

:VirtualHDIrq=<Boolean>
:  Default: on
:  Purpose: Allows Windows in 386 enhanced mode to terminate
:           interrupts from the hard disk controller,
:           bypassing the ROM routine that handles these
:           interrupts. Some hard drives might require that
:           this setting be disabled in order for interrupts
:           to be processed correctly. If this setting is
:           disabled, the ROM routine handles the interrupts,
:           which slows the system's performance.
:  To change: Use Notepad to edit the SYSTEM.INI file.
Note: I assume this is copyrighted by Microsoft, but I'm also assuming you
all have it your own copy by now.

  Just change or add the entry to say false.  My read/writable optical disk
drive needs this setting, but I don't have an HD partitioned w/ OnTrack stuff
to test this.
