From the point of view of creating a CD, does this
matter? Or is the
block size issue only to do with transferring data from the CD unit to
the host, and iso9660 is the same on both platforms?
The block size just reflects how the host machine
chooses to read (or write) the data. The actual
pattern of bits on the CD-R(W) is not affected.
I've written a few ODS-2 CDs (OpenVMS format) quite
happily on a PC CD-RW (and now a DVD-RW). I've also
written a few CDs for my Ultra 5 too.
If you want to swap the CDROM in your SGI (or Sun
or VAX or Alpha) you will need one that meets its
requirements, obviously.
