Examples

## get the root block from the example adf:
amigaBlock(adf.example, 880)

## Create a completely blank disk without file system:
blank.disk <- new("amigaDisk")

## Replace the boot block on the blank disk with
## that from the example object:
amigaBlock(blank.disk, 0) <- amigaBlock(adf.example, 0)

## The blank disk now has a boot block,
## but still no file system...
