After poking around some, it seems ATA/ATAPI-7 Identify Device word 106 bit 13 is set to 1 and bits 0-3 are set to 3 (for 2^3 or 8 LBAs per sector) for a 4KB sector size (pin 7-8 jumper on a WD AF disks presumably changes this setting to 0,0). See page 121 of Atapi-7 volume 1 (google for ata-atapi-7.pdf).
Hopefully this helps in whatever `clean solution' you are looking for? _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
