Since I posted my last summary I ahve gotten several responses from people
wanting to know what the patch was or how I modified my drive.
Well, Here is everything I know about Toshiba CD-ROM Drives and The HSFS Patch.

I obtained the following patch for the HSFS driver from Sun. I think
it will fix your problems.

For the NASA CD's, the 4.1.3 patch is the same as the 4.1.2 version, which I've
included below.

Subject: NASA CD's and SunOS 4.1.2
As you found out, Sun cannot read the guide star
catalog cdrom from NASA. This is because all of the data
files are of type RECORD, which Sun chose not to support because
there is no UNIX interface to access the RECORD structure file.
Attached is a kernel patch that you can make your Sun
machine to read the guide star cdrom. As a precaution, please
save your old kernel before applying this patch.
for SunOS 4.1.2 & 4.1.3

You need to reboot.
You can also edit the file in OBJ/hsfs_node.o.
Feel free to pass along this patch to those who need this fix.
