Every CDROM drive placed in a PC supports 512 byte sectoring (usually right out of the factory.) The rarer find is a 2048 byte sectored drive common to old Sun hardware -- infact, most Sun's cannot boot from a CDROM that doesn't power up in 2k mode. (All of my plextor drives have a jumper for setting the block size.)
Personally, I wouldn't blame the drive. The biggest problem is the limit in the HFS driver.
