Start DST Short Test failed, can't boot - recovering data

Hello!

A week ago I posted the message that - when booting - I get a bluescreen and the diagnostic utility says Start DST Short Test failed....

I have been told that bad sectory have developed - unfortunately in these placed where some files necessary for booting are located...

however, there's still a guarantee

I have installed the HDD in an external enclosure, so I've already transferred my files, screensavers & fonts and so on to another HDD - so far so good. But one thing that's still missing are the EMAILS. Emails which are in Outlook Express plus the different accounts I'm using (well, I still know the settings, but I'd like to just import the account to my new installation)...

IS THERE ANY CHANCE of getting these MAILS (at least, and to go further also the accounts) WITHOUT starting the system with this very HDD (which is currently not working)... where are these mails stored? or do I have to try to get windows working again to access Outlook & the mails?
