My Second Hard Drive

I recently FDISK and FORMATTED my C: drive which set up as primary master. I left my D: drive alone which is set up as primary slave. I wanted to save the contents of the D: drive. Now when I Windows 98 reinstalled and every thing on my C: drive is working windows will not find my D: drive. The D: drive is recognized by the CMOS and I can see it during boot up, but it will not show up when I double click the My Computer icon. Someone got some ideas.
