Good day (again),

I've recently been archiving pre-compressed data in bz2 format to tape. I'm 
quite certain that my SDLT drive's hardware compression is not as good as 
bz2, so there probably isn't too much compression going on.

The reason I'm saying this is that I was able to fit a mere 142 gigs on a tape 
which is meant to have a NATIVE capacity of 160 gigs.

This rose a few questions here. Is this analoguous to the way hard drive 
vendors count hard drive space in base 10 vs base 2 for computers? In this 
case, I shouldn't be loosing any more than 2.4% of the space (1000KB vs 
1024KB). (142*100/160) tells me that I've got a 11.75% loss of space, which 
sounds a bit too much to me.

Anyone can shed some light on this?

Thanks,
