I know of one person using a really large ESDI disk on an RT w/4.3. He
has a Wren VI (780M) disk. The problem is that it is not supported by
any of IBMs normal controllers because it is too fast, so he uses a
prototype controller (HESDI I think). I suspect that many of the disks
would have a similar problem with controller speed i.e. the regular
FESDI controller would not handle them.
