My OS supports all three versions (CHS, 28-bit LBA and 48-bit LBA), but would use 28-bit LBA as a first choice if the full disk capacity can be used with 28-bit LBA. It would only use CHS as a last resort if LBA is not supported.SparrowOS wrote: This whole discussion occurred because rdos said 28-bit was faster than 48-bit. That seemed to me as silly as saying CHS was faster than 28-bit. If you had a 1TB drive, who would use CHS even if it was faster? rdos is suggesting you only use the first 130Gig of a 1TB drive because he thinks the negligable port I/O time saved is worth it. In actual fact, he is a troll arguing for his own operating system that supports 28-bit and not 48-bit, being silly and dishonest.
OTOH, I still use only 32-bit sector numbers, but I might change that some day when it becomes a problem.
