    Some drives have firmware tweaks downloadable from the manufacturer which
    can be used to force the drive to never negotiate a faster data rate than
    UDMA33 (or whatever the cable you are using is capable of). I'm thinking
    of Samsung in particular here.

    However, I agree, this is *annoying*; I don't know of 80 + 4 conductor cables
    for 2.5" ATA drives. If anyone knows of such things then please do let me
    know, as I've had significant problems with a development system at work which
    is Mini-ITX form factor based with a 2.5" drive.
