If you need very large partitions, please use PFS3AIO or a similar file system instead of FFS.~~ - * ~~Selecting a different block size may appear to work in some cases, but in reality it does not.

You can check what type the disk image is using a hex editor, if it starts with `RDSK`, it is a full drive RDSK/RDB image, if it starts with `DOS` it is most likely a UAE single partition disk image. * It **does** however work with any UAE disk image prepared using the **Full drive/RDB mode** selected in the Hardfile settings.
