HDD Utility

I'm thinking this may be a stupid question, but here it goes. Is there a
tool out there that will tell you the cyl. heads and sectors of the HDD if
you only have the size of the HDD. So for example, if I have a 300GB SATA
HDD, can I find out the BIOS info with some sort of formula?

Is there some reason you cannot set bios hd for auto detect?

I can, but I'm just asking to see if there is such a tool/fomula out there,
for the just in case purposes. I also, understand that the manufacture of
the HDD should have this, but again, just in case they do not. If there is
no such tool/formula then maybe someone should make one. I think it'll be
useful, but who knows....

There is a command on ATA devices "Identify Device" that is used by many
diskutils (often Dos programs like ATAPROBE) to read 512 bytes of
information from the device.
Among this the total number of sectors that is used instead nowadays and
a default CHS you can use to read the beginning of a disk.
(On outer tracks the number of sectors is higher than on the smaller
inner tracks.)
