I was guessing, the numbers you get from a free /device need massaging to 
make human readable decimal numbers and I was using pure SWAG's. ;-)

That compression is because there are lots of files that consist of the fd 
sector, and less than a sector of data.  bru compresses the fd sectors 
away, only storing the file, with a min allocation of one sector IIRC.

Always did to me too.  OTOH, leaving the sas set to some huge number 
doesn't really waste a lot of disk space because its all corrected to be 
just what the file occupies when the closing code is executed.

But after the crash, or the rooting as the case may be, his site was rooted 
once too.

Sounds about right, and if I don't go light a fire under some pork chops, 
me & the missus are gonna starve. ;-) Later.
