There may be some bits of software that suggest they can use them, but I think with the advent of LBA directly addressing CHS is now retired with only sector addressing being important due to the way the data is physically placed on the drive. Who cares what cylinder it's on, and who cares which head is getting the data? It doesn't matter to us users... Cheers, Mark
