Amiga floppy disks cannot be read on PCs without installing
additional hardware such as a special floppy disk controller or a
second floppy drive.
As Amiga users know, this hardware incompatibility has limited Amiga-PC data sharing
since the the Amiga was released in the mid-80s, and, although newer software and
hardware have helped overcome this limitation, there is no way that software emulation alone can solve
it: a
PC cannot read Amiga disks using only the default PC floppy disk controller
and disk drive.
The opposite is true,
i.e. the Amiga, which has a more "flexible" hardware than most PCs, can read and
write floppy disks in the MS-DOS format. The Amiga Forever CD-ROM includes the MSH file system, which allows users of all Amiga operating systems from version 1.2 upwards to read
and write MS-DOS floppy disks, which can then be used to share data with PC systems.
We
recommend Amiga Explorer as the easiest choice to transfer data between the Amiga and
Windows systems. With Amiga Explorer, an Amiga computer can be connected to the
PC via a null-modem serial cable or TCP/IP (e.g. Ethernet), and
then be accessed as a "virtual floppy disk" from the Windows Desktop.
The
Amiga computer itself does not even require a monitor, if it is booted from
a floppy disk which also launches the Amiga Explorer server
software, which easily fits on a bootable disk. Amiga Explorer is
included with Amiga Forever.
Four solutions are known to be able to connect Amiga drives to the
PC:
- The adfread software by
Toni Wilen and Simon Owen, combined with a second floppy drive.
This software works with the most common floppy disk
controllers used in industry standard PCs, requiring no custom
hardware other than an inexpensive additional PC floppy drive,
connected to the same cable as the first drive.
This is a read-only solution, and only supports
Windows 2000, Windows XP, Windows Server 2003, Windows Vista,
Windows 7 and Windows Server 2008 (not Windows 95, Windows 98,
Windows Me or Windows NT).
- The Disk2FDI software by Vincent Joguin, combined with a second floppy drive.
This is the original software which inspired adfread, but it
only supports Windows 95, 98 and Me (not NT, 2000, XP or Server
2003 or newer).
- The "Catweasel" floppy controller, by Individual Computers, which is
available both as a PCI and as an ISA board
(to be mounted inside the PC) to which the disk drive can be connected. The Catweasel is
also available for the Amiga, but the one needed here is the PC version.
This is a read/write solution which supports all versions of
Windows except for Windows NT 4.0 (Windows 95 is supported via
DOS software, newer versions of Windows are supported via WDM
drivers).
- The "Amiga Floppy Reader" (AFR),
designed by Marco Veneri, is an interface which can
connect an external Amiga floppy disk to the PC's parallel port. This is a
read-only solution with DOS-only software.
Cloanto also offers a
data conversion
service, which may be of special interest to convert a few floppy disks
without installing special hardware.
Other solutions are known to be in development to provide at least read-access to Amiga
disks through an interface on the PC's parallel port. Symantec in the USA used to
manufacture a controller card providing capabilities similar to the Catweasel's, but
it
is no longer in production.
Amiga emulation programs like UAE and Fellow use "disk images" of Amiga
floppy disks. The most used file format used for these images is called "ADF"
(from "Amiga Disk File"). Each Amiga floppy disk can be stored in an ADF file
(or split in more than one ADF file). ADF files can be created on an Amiga with a tool
like "transdisk", or they can be created on the fly by Amiga Explorer. Both are
included on Amiga Forever. Both the Catweasel and the AFR hardware come with
software to create an ADF file from an Amiga floppy disk.
Please note that ADF files and the other disk connectivity tools described here
currently only support standard Amiga floppy disks, and not certain non-standard
"copy protection" schemes, which in part also fail on different types of
original Amiga floppy drives. If the Amiga DiskCopy command cannot copy a
disk, it is likely that the creation of the ADF disk image file will also
fail to produce a working result. For archival purposes, you may want to create
a disk image in DMS format (DMS supports a few simple copy protection
schemes), if possible. It is also likely that a future version of the
emulation software will include extended direct support for hardware such as
the Catweasel so as to also support copy protection.
The Amiga Forever
Game Downloads page includes a variety of sites hosting disk images of
famous Amiga game disks, as well as other software. These games have been
released for online distribution by the original publishers. It is very
likely that any Amiga games you may have on floppy disk are now available
for download in this format, with copy protection removed, if so required.
