I have a disk with geometry: 2586/240/63 [39100320 Sectors]. The number of platters on the disk is 4 but the number of heads 240 and I know that this is because how BIOS calculates it. Dont know why though.
Since BIOS doesn't know much about large disks, BIOS lies. But that's okay, because the disk lies, too.
If I create a partition with start CHS 0/0/1 and end CHS 0/60/1, will that roughly create a partition that spans a physical platter or does BIOS
Not so much BIOS as the electronics on the disk.
completely recalculate head values and I there are no guarantees where data will actually end up.
Yes, there are no guarantees. Go ahead and let the disk electronics do what it wants.
