I need some professional opinions regarding this software because i asked almost all my friends what's the best software for encrypting hard-disk data and most of them gave me the same answer : PGP . I heard a lot of good things about PGP, but before buying the software I really want an answer for this situation :
In my opinion this software is designed to PROTECT peoples data against anyone, but two weeks ago a friend who work as policeman in Belgium told me that PGP can be cracked by their IT guys if the person who is using the software, decrypt informations every time before reinstalling the OS . After I read a lot of stuff about pgp, and after I talked with all my friends they told me they are using pgp like this : they install the OS (usually , windows XP), after installing the OS, they install PGP software and encrypt the whole disk. When they want to format their pc they decrypt the HDD , then format, reinstall the OS , then again reinstall the PGP and encrypt the hard-disk again. As I said upwards , I heard that if you are using the PGP this way, the hdd can be somehow cracked or the PGP bypassed, not very sure, because my friend who work in police is not working in IT department .
I suppose if I uninstall the PGP without decrypting the hdd, I wont be able to access my hdd anymore, because I believe its encrypted, right?
So, my question is , if I will buy PGP , how can I use it properly? How can I have the maximum rate of safety with this software? I really want to buy this software if its GOOD and if offers protection, so I really need some opinions.
PLEASE, POST ONLY PEOPLE WHO ARE USING OR WHO USED PGP.
Thank you very much guys.
