Yes.  The AE drive will read and write stanard amiga disks as well as HD.

The High density drive acts as two logical drives.  One standard amiga and
the other high density.  For example, on the machine that was shown at the
meeting was an A500 with one normal drive and the AE drive.  The AE drive
was DF1: for low density and df4: for high density.  If you tried to do
an operation on df4: when there there was a low density disk in the drive
the error "disk not present" was returned.  Presumably it detects this by
checking for the hole.
