Re: big non-boot disks

usually yeah, or get the tech specs from the www site from the maker of
the drive.. the only barriers i've found with ide are 540(545?)MB 8GB and
32GB haven't encountered/read about problems with stuff inbetween those,
although i dont doubt there are some really broken bioses out there.

one of systems i built a few months ago with a 37GB ibm drive did not
detect teh drive in the bios, or if it did it didnt show me the geometry
of the drive it was just blank, but for some reason i was still able to
format and install/use it not only as a bootable drive(with a 6GB bootable
partition) but i could (apparently havent really tested it to its full
extent) access all 37GB of the drive. 

and in another case, with a really old computer, the bios stopped
recognizing ANY drives at all, and yet when i booted a linux kernel from
floppy i could read/write/mount drives no problem. it must of bypassed
bios calls to detect the drives, as when i booted to dos and tried fdisk
it said 'no fixed disks present'.

moral of the stories i guess even if the bios can't see the drive right it
still might work :)
