Dear user:
I am wondering why you need this!
On old IDE drives the CHS information was written on the disk... and was kae
anyway, but useful for BIOS setting.
For a long time (over 10 years) IDE/ATA has a query command to query the CHS
information: the host can request and get this info from the disk.
There even was a command to change it (YES!).
Today, the data is accessed by LBA (logical block address).
A logical block is still often 512 bytes of data, but in my opinion it
should be bumped to a higher number, like 2k (2048 bytes).
So you really do not need to know the number of CHS on your disk excepted
for curiosity.
