OS4 classic and FastATA

@SimplePPC

Have since found the problem seems to be with the second drive.

I can get round it for the moment.

Under both drivers the error says something along the lines off to put back the drives/partitions dh1 dh0 whatever as data has not finished copying across.
The partitions are there though but can't be accessed.

If I reboot and disable the partitions in the early startup on the second drive, they come on ok and can be used.

Alternatively, I can disable the automount option and just mount the partitions after the OS loads.
