RE: More than 256 sectors per track?

Hi Marko,

From all the drive specs I've looked at none of the drives go beyond
256tracks and 256sectors. Even CMD (and 64HDD) partition numbers are limited
to 256 when requested in binary, though 64HDD can support 999 if requested
in ascii and later will support "fff" when requested in ascii (but read as

I don't know the inner workings of IDE64, but assume it is limited to 16bit
clusters, with each cluster set according to drive size.

A similar cluster concept could be applied to CBM drives where 256x256
define the cluster, cluster size depends upon the media - it could be 256,
512, 1024 bytes long.

No, I don't think so, with the possible exception of the IDE64. The
CMD HD has a 16 MB partition limit for this very reason.
