Did you use real double sided/double density disks?  These have
one less hole than the high density kind.  They two have different
magnetic properties.  Formatting a HD disk an 800k and trying to
read it on the IIGS' double density drive may cause problems.

Second, save some time.  Diskcopy, if I recall, uses a block copy
to unimage the disk.  Thus, you don't need to first format the
disk as ProDOS.  Just format the disk as HFS, then unimage a
System 6.0.1 disk on top of that.  The disk automatically turns into
ProDOS.

Once you get System 6.0.1 working on the IIGS, you can do all
your transfers using HFS since the IIGS can read and write
HFS disks using System 6.0.1.
