the intersting bit is right at the end
where two request sense commands are sent back-to-back
and the second one returns all good (since request sense
clears sense information).
this same disk works fine on a sata cdrom. so either
- this cdrom does something cdfs can't handle, or
- usb/disk is doing something cdfs can't handle.
as a guess, it looks like usb/disk errored out 0xa8 (read 12) before it
was sent.
