I have made huge archives many times.
The secret trick is to assign T: to your HD somewhere like this:
Assign T: Work:
Also I advise you to create the archive directly onto your amiga somewhere if you have the space for it. I am afraid it will take over 24 hours if you do it over the network. But you are free to try whatever you like. :-) Your smbfs may be new/faster/better than mine.
Also I like to addbuffers 2048 to wherever T: gets assigned and also the partition you are archiving. This speeds things up.
And make sure you are using a RELIABLE version of lha. Any lha 1.x is good. Most lha 2.x will create corrupt archives of huge data. I learned that the hard way. :cry:
