Re: Somebody straighten me out

That's it! (you're example of DDMF's)

We had been using the intermediate v7r1 partition method, and had 
automated the whole process, until we lost a drive, found out we didn't 
actually have RAID enabled, had to rebuild our system from scratch, and 
lost/did away with the v7r1 partition.
We were only using the v7r1 to transfer source files back and forth and 
I was confident we could do it without the partition, ftp, etc.

Hat Tip for the recollection!

Thomas Garvey
