Well, the votes are in and everybody says that 8Gig is a dream. I pretty
much knew that but I was hoping to get a bit more than 3Gig.
One person says he gets 2 - 2.5 Gig on a 60m tape. So 3 - 3.5 should be
doable for 90m - depending on the type of data you have, of course.
Also, the s and the d flags don't matter, just so long as they are large
enough so that dump doesn't think its about to hit the end.
