I've heard that was true of any drive over 500mb and have not seen anything
over 80mb that does.
Me I keep saying if you really need the simplicity of 8b transfers and
the low cost that comes from a surplus IDE drive just ignore the high 8bits
and enjoy it. There's no harm from that. So what if half the storage
is unused, likely the drive is large anyway.
You are going to lose the error flags from the status register which a
transferred on D8-15, IIRC.
Also the drive identify command will return only half of the data.
It is not an issue with pure data blocks; you'll then just have 256 byte
blocks rather than 512.
