63s/255h is more or less "standard" now. Alignment issues can be solved by picking a good multiple of _heads_ or _cylinders_: For first partition, pick the start at 8th head: cyl 0 head 1 sector 1: LBA sector 63) - bad cyl 0 head 8 sector 1: LBA sector 8*63) - good (4k aligned) For any other partition, pick start cylinder which is a multiple of 8: cyl 8*x head 0 sector 1: LBA sector 8*x*255*63 - good (4k aligned) This will actually work well for *any* geometry, not only for 63s/255h.
Yes, but it does squat for a flash disk that wants, say, 256K alignment. -hpa -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
