Can’t see partitions after XP reload

I have a 250G HD, which I have partitioned into 5 x 50G partitions. the first partition “C” I use as my Boot drive. I had a virus, therefore the only way to resolve my problem was to format C and re-install XP. Now I can’t see two of the original partitions. Using Disk Manager, the space for these two partitions is showing as Free Space. I have some data on these drives I really don’t want to loose.

Any suggestions???
