Storage Devices
USB drives and Compact Flash cards store the data that your Apple II will see as virtual disks. You
can insert and remove them any time, without turning anything off, and without rebooting the Apple
II. Choices of which disk image files to use are stored in a file named CFFA.CFG in the root folder
on the USB or CompactFlash media, but you don
‘t have edit this file manually.
When formatting a Compact Flash or USB device, ensure that you format it with FAT16 or FAT32
and with a Master Boot Record (MBR)
Note: Media formatted FAT12 or NTFS will not work with the CFFA3000.
Memory storage devices generally come this way when new. The Mac Disk Utility may not put a
MBR on your device by default if you format it yourself; so you need to click on options and choose
it. See Figure 5 for an example.
Figure 5: Partitioning and formatting with FAT16 or FAT32 and MBR required.
Restoring an MBR to Media using Windows 7 or later
In some rare cases it may be necessary to write a valid MBR to a flash media because it has been
erased for some reason. One example would be CF cards that were used in CFFA with a native
ProDOS partitioning scheme.
The following procedure has been tested to work under Windows 7. This procedure will erase all
data on the media device.
1) Open a command (CMD) window with administrator privileges.
a. Click Start->All Programs->Accessories.
b. Right-Click on "Command Prompt"
c. Select "Run as Administrator".
d. Answer "yes" if prompted for permission.
