Did you burn the iso's to CD yet? Alcohol 120% does this well, at least it worked well for me under XP, and 30-day demo is free. After they're burned, boot from the first CD and see if Fedora can find the sata drives.
However, assuming XP is on drive one, you will also need to need to set up partitions (other than fat/ntfs) on the second drive during the install process to house Fedora (ext2/3 fs); although Fedora can safely read/write fat32 partitions (ntfs will be read-only), Fedora will want ext2/3 as the native file system for the / and /boot paritions. /home can be fat32, and thus you'll be able to r/w this partition from XP.
