I have SUSE 10 on my laptop where I've been playing with some fairly big 
files. I just tested a smaller one, a little over 6 Gbytes compressed,

It's fine.

My files are not tarballs, they're images of paritions and disks, and I 
did not pipe them into bzip2, I wrote the data to the files and then 
compressed them. I don't know whether the different way I compressed my 
data is relevant, but it might be.


I don't use tar that way, I always tell tar to do the compression. It 
should not be different, but it might be.
