ok, I have a sony cdu31a cdrom drive.

it does not use a caddy.  It is supposed to be single speed.
sustained transfer rate = 150 kbytes/secons
Burst transfer rate = 2.1 Mbytes / second

(from manual)

now my neighbor has a sony cdu31a caddyless (ahem this is same as mine)

however his is supposed to be a double speed.

I don't have his manual handy but the numbers show double speed type 
transfer rates.

so, what is up?  Was there a factory upgarde to some cdu31a's?

or is there another explanation?

any info you have would be appreciated.
