No.

You can use a 720k 3.5" drive, but not very easily.  To use this drive,
you will have to sand off the connector key, and attach it upside down
(relative to the way IBM drives are keyed.)  Assuming the terminating 
resistors are removed, and the drive select is set to 1, it will then 
work marginally well as a df1:.  Unfortunately since it doesn't recognise
the Amiga identify request, it won't autoconfigure.  Fortunately, the 
identify response for a 3.5" drive is all 1's (ie: 0xffffffff).  To 
get your amiga to recognize the drive you will have to leave the drive
empty whenever the machine is rebooted.  Some programs (especially 
copiers) won't work well with this setup.
