But then you should do a 0 byte format to delate all data if you do it on pc. Otherwise data will not be 100% delated. You can do this by using Hexedit and format hdd with 0 byte. Its an option you can use.
I've updated to OFW about a month ago and no problems yet, I play online everyday. I did delete my homebrew and backup managers before upgrading though.

A zero fill takes a long time and is unnecessary. Basically when data is typically "deleted" on a hard disk it's not actually deleted, it's still there but just marked not to be read and that it can be written over, so it will show as free space. So as you write to your HDD that old data is eventually gone for real. In this case he can do a normal quick format and he'd be fine, Sony don't have magic, they're not going to be able to read his files marked as deleted.

Of course they are, they can access HD on sector basis and therefore read sectors/blocks that were marked 'free' in filesystem and examine this data. I doubt they do that - but they could do if they want to. Safest way for NOR units is to wipe complete HD with zeros. NANDs may have left some hints even after wiping the HD.
