I'm fairly sure. At least at one time. Also true according to: http://www.dewassoc.com/kbase/hard_drives/hard_disk_sector_structures.ht m <quote> Early hard disks had the same number of sectors per track location, and in fact, the number of sectors in each track were fairly standard between models. Today's advances in drive technology have allowed the number of sectors per track, or SPT, to vary significantly, but more about that later. </quote> -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
