Hello everybody,

i've read thru the list and found out, that there was a bug till 
recently using gbde with lesser than 4 keys.
I started to use bde with a different sector start and 2 keys.
I am about to upgrade now to 5.3BETA6 since the pci solts on my new 
mainboard that i spend to my server are not working proper on 5.2.1. 
Well.. i ended up now with latest code at "incorrect superblock" when i 
try to mount the fs on it.
Wanted to know what settings are "safe" to use in the future, since i am 
testing a 300+ GB storage and its pretty anoying to dump and restore 
that :).
I was reading phk's nice doc about GBDE and how it works. But i am still 
unsure.. if 2 or 4 keys would make a difference in the question of security.
For now i will stick with 4 keys, since i might boot 5.2.1.

Greetz,

Stephan
