Curtis, The A3000 has an onboard SCSI controller, so a PC's IDE, EIDE, or SATA hard drive will not work, unless an IDE controller on a Zorro card is added to your A3000. Your floppy drive most likely can only access Amiga 880kb floppy disks and if you have the PC0: device driver in your Devs directory, you should also be able to read/write PC 720kb floppy disks.
