Get the PFS3_53 archive from Aminet and install it. It contains the complete distribution with tools, documentation and everything. Just use PFS3aio when it talks about PFS3 or PFS3ds. You can as well use PFS3ds, aio brings no benefit for you.

Once you have a file system which supports accessing outside the first 4GB of a harddrive, you can make partitions as big or as small as you like. The issue is the position of the partition on the harddrive, not its size.

SFS does not support harddrives bigger than 4GB without a patch for scsi.device.

The same is true for PFS3 (normal version). Only PFS3ds or PFS3aio do.

For an 8GB card you shouldn't need a patch, just use PFS3ds or PFS3aio.

Note that a patch of scsi.device implies an automatic reboot which almost doubles the boot time.

Depending on how accurate the CF card reports its size, you should make the last partition one cylinder smaller than shown and leave the last cylinder of the card empty. Some cheap CF cards report themselves one block bigger than they actually are. If the file system then checks the accessibility of the last block, it fails with an error message. (PFS3aio checks accessibility, PFS3ds doesn't).

How do I reduce one cylinder there?


Reduce End Cyl by one.
