Need to recover Outlook 2003 entries

Hi! My hard drive died but I can still get to the data. Around the same time, my Dell Axiom reset and I lost everything on it. I rebuilt my system on a new drive and need to recover my Outlook data from the bad drive. Does anyone know how to do this? I have a backup.pst file but it is too old. Thanks!
ps, I know, I know. Should have been doing more frequent backups. :-0
