Default Large IDE drives not compatable with old systems

Larger disks use LBA addressing


So do smaller disks, LOL!

LBA is a particularly simple linear addressing scheme; blocks are located
by an integer index, with the first block being LBA 0, the second LBA 1,
and so on.

IDE standard included 22-bit LBA as an option, which was further extended
to 28-bit with the release of ATA-1 (1994) and to 48-bit with the release
of ATA-6 (2003). Most hard drives released after 1996 implement Logical
block addressing.
