How much hdd space is recommended for BT
it depends on the use, i have given a 30GB partition on my External hdd, which will share the boot, swap and root partition..
actually some recommend 50GB or more if you are a heavy user, as the updates and table generations take alot of space (like rainbow tables or some db tables storage
)..
I will install it as soon as my external frees up from the work, and i'll follow this guide for reference: Install BackTrack 5 Revolution 2 on external hard drive
though i am a little concerned about the second last screenshot in which it says "sda would be formatted as swap"..
i don't wanna messup with my data on internal hdd, so let's see what comes up with the installation..
