Re: change hard drives (?)

the only reason you would lose your trophies is if you forgot the exact username and password for your psn account.  you need to ensure you keep note of your psn account… im not saying write it down because you should never write down any of your digital passwords.

Anyway, another thing to note is not to change your psn account… try not to change the password unless you NEED to, and don't change your e-mail address (the username of your psn account) either because it can cause a recent, and well documented problem with trophy synchronisation.

so if you don't change your psn account, nothing bad can theoretically happen.
