Hello,
Till now, all disk descriptors (in sector 0) I had seen for magnetical disks and CD-ROMs began with 45 52 02 00, that is the physical sector size was always 0x0200 (512d) even on CD-ROMs. On the other hand, I had seen 0x0400 on magneto-optical disks.
Yesterday, I cam across a CD-ROM burnt on a Mac Mini with the integrated burning tool and, to my surprise, I got 08 00 in positions 2 and 3 above.
Any comments?
