Well, I have two 4.3 hardrives and BIOS shows same thing to me. First
hardrive has 9 heads and shows that 82MB and another have 15 heads and
show something over hundres MB, but not what it supposed to be...

If you are going to use linux with that drive then you must use NORMAL
mode. I noticed that number of heads affect how much DOS FDISK says size
to be use. This drive have only 9 heads and lots of cylinders, so 1024
cylinders mean only 283 MB room for DOS. My another drive have 15 heads
and there is about 480 MB room for dos, not 519 MB..
You must use diskmanager program if you want more disk to dos. I check
quantums diskmanager for fireball and I didn't install it. It wanted to
repartion of hole drive and that was last thing what I want...

I dont't think so...

Set dos compatiblity flag off when you do new partitios to drive. It do
that kind partition overlays...
