Lost emails on crashed hard drive

Hi Folk,
I'm running an HP desktop computer with Windows 7 64bit. One day the the computer simply wouldn't boot. I took another hard drive that already had windows on it and put it in the computer. I used the crashed hard drive as a slave and found that a lot of the data files were still intact. I'm using Windows Live 2012 Email and I can't find any of the emails. The Windows Live folder is there but not the folders with the emails. ( I have transferred these emails to other computers in the past, so I think I'm looking in the right place)
So my question is... if I try to reinstall Windows on this corrupted drive will it wipe out the data files that are still there.

Thanks for the help

1. Where are you looking?
   
2. It depends on how you do the install.

In the past I have found them in C:\users\mylogon\appdata\local\microsoft\windows live mail

But most of the folders are missing. my logon folder is missing. it looks like there is a Windows live folder, but I'm not sure what's in it.

Thanks for the help
