22: they are just straight images of the disk in question, with sectors stored in
23: the expected logical order. So, on a sector basis the images run from sector
24: 0 (bootsector) to however many sectors are on the disk. On a track basis the
25: layout is the same as for MSA files but obviously the data is raw, no track
26: header or compression or anything like that.
