You can use a PC 1.44MB floppy drive as a HD drive with an adapter, the trouble is that it will not physically fit in an A3000 case because of the moulded front panel.
Your only chance is to get a replacement A3000 floppy drive (either 880k or 1.76M) from an Amiga shop or off eBay or to refurbish your own unit(s) yourself.
Cheapest way to replace an A3000 hard drive is to buy a
cheap SCSI card off eBay and a second hand
SCSI hard drive. Narrow 50-pin drives are hard to find so you'll probably need to get an Ultra320/160 one plus an
adapter). In total it should cost under £15 and you'll be able to partition, format and install AmigaOS3.9 + Boing Bag 1&2 and all your
WHDLoad games and applications onto the hard drive using your PC using WinUAE at lightening fast speed and take care of things such as FileSystems and max partition sizes before you even get to your Amiga.
