>Description:
I have two physical computers with mobile racks and I pull out winXP and
put in freeBSD 4.11 or freeBSD 5.4 in each of them.  I used to install
multi-OSes on the same physical drive, but Microscrew made me sorry I ever
did...

I've been working this issue for about five days and have discovered that the
problem only occurs with the specific combination of high speed media
(Memorex 4x-12x) and freeBSD 4.11.

When I used 5.4 with the high speed media, it works fine.  If I use low speed
media with 4.11, it works fine.

Some freeBSD people have suggested that 4.11 simply can't be brought into
compliance with the SCSI i/o model in the 5.x series.  I'm going to continue
my troubleshooting awhile longer and see if it's just something not
configured properly in my 4.11.  I don't believe that's going to be the case,
but I'll look.      
>How-To-Repeat:
Acquire Memorex HIGH SPEED CD-RW (4x-12x) media and burn it with cdrecord under 4.11-STABLE.  cdrecord doesn't report any errors, but when you mount it, you'll get an i/o error. If you then use cdrecord -blank=all, it will complain that the media format is corrupt.
