Many thanks for any replies - I'm at wit's end. The mother board crashed on my Pentium III system (been great for about 8 years!!). I need to get my windows app data from the HD. I can use it on as a slave on another computer but since I can't bring up (can I?) WIN from the slave I can't get to my Internet Explorer nor Firefox favorites. I can't get to my Outlook address book nor folders. I really need these files. Can anyone tell me 1) how to identify these and where they are 2) how to get them to my new master disk? Both computers are WIN XP HOME. I thought I could just take the old HD and put it as a master in the new PC but I found and was told that this is not possible due to some relationship between the HD and the system it came from. Please help!
