Hard Disks


When mounting a directory as hard disk in WinUAE, files will be placed into the host directory. However, the Amiga file systems used different and/or additional meta information, so by default, UAEFSDB files will be created which store this extra information, such as additional protection flags for files when using the Directory type of file systems.


Hard disk files are large files that contain the image of an Amiga file system. They work much the same way as a disk file. You can simply create a large empty file and tell UAE to use it as a hardfile, but you will need to format it from the emulation before you can actually use it.
If you are want to boot a hardfile under Kickstart 1.3, you need the FastFileSystem file from the L: directory to be placed in the Kickstart ROMs-directory where WinUAE is installed.

If you are using WinUAE 0.8.22r1 or earlier and Kickstart 1.3 or earlier, hardfiles can't currently be mounted at boot time, and therefore you can't boot from it either. You will have to boot either from a Floppy Disk Image or from a file system, and mount the hardfile.device later. To do this, add the following to "DEVS:mountlist":

Device = uaehf.device
Unit = 0
Flags = 0
Surfaces = 1
BlocksPerTrack = 32
Reserved = 1
Interleave = 0
LowCyl = 0 ; HighCyl = 511
Buffers = 5
DosType = 0x444F5300
BufMemType = 1

You may need to adjust the values if you specified a different geometry, and/or your hardfile has a different size than 8MB, and/or the hardfile is not mounted as UAE0: because you mounted other hard disks before it. Then, type "mount UAE0:" (or put that command in your startup-sequence), and you should be able to access it. Don't forget to format it with the AmigaOS!
If using HDToolbox to manage Hard files, you must create hardfile normally or use hard disk image from your real Amiga but clear all hardfile parameters except block size.(sectors, surfaces and reserved). HDToolBox must be run with "uaehf.device"-parameter ("tools/hdtoolbox uaehf.device")

Mounted Drives

The following conventions apply for mounting drives:

  • If the drive-letter has a Windows volume-name associated with it, the drive will get mounted in the Amiga using its volume-name. On PCs, the volume name can be set via the Properties of the drive in My Computer.
  • If no volume-name, the drive gets assigned an Amiga volume-name based on its drive-type (the 'x:' is the PC drive-letter):


Drive Letter

Hard Drives


CD-ROM Drives


Floppy Drives


Network Drives


Removable Drives


RAM Disk Drives


NOTE: If a drive doesn't currently have a disc in it (floppy, CD-ROM, etc.), then this option will NOT mount the drive for use by the Amiga.
