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. Regards, BMS
