Hi!

I'm trying to access block directly on hard drives, but (obviously) I've got a
problem:

I OpenDevice(...) fine, but when I go to do a DoIO(...), my machine crashes. If
I do an OpenDevice(TD_NAME....), and turn on the drive motor, then do the
DoIO(), it works fine.  What could I possibly be doing wrong?  My assumption is
that  CMD_READ,CMD_WRITE are universal for all devices, trackdisk or whatever.

Thank you very much for your help in the past, people! (And for putting up with
these questions....)

James
