I knew that, I was wondering what advantage SCSI Manager 4.3 gave to
Macs that you would prefer to use it over the one put on drives
formatted with a IIgs.

There doesn't seem to be anything here that says that you can't use
the old GenericMacSCSI driver with SCSI Manager 4.3.  

I suppose if you want more than one SCSI controller in a Mac you might
need to use 4.3 but you don't need it for the IIgs.  It supports
multiple SCSI controllers without a problem (with the exception of DMA
conflicts on high speed cards).

I'm not quite sure what asynchronous data transfers are, though.

I'm still curious why you would want the newer driver on a IIgs
formatted harddrive.  Does the newer driver give you faster access to
drives with the newer driver?

Because you never know when I might want to share data with a Mac
owner or when I might pick up a used Mac.  If there is some benefit to
using the SCSI Manger 4.3 driver then I would like to make sure I use
it.

However, you mentioned in another message, and this is something I've
heard before, is that the IIgs chokes on the APPLE_DRIVER43 partition
because it doesn't recognize it as a Mac driver partition.  My
question would be, why would you want to use this driver on a hard
drive for use on a IIgs?  Seems to me it would cause a bit of a
headache for the IIgs user.

And again, this is all out of curiousity and so I can learn more.
This info might come in useful for me sometime in the future.
