PC Inspector File Recovery is a free data recovery tool. It supports FAT and NTFS file systems. It can find partitions automatically even if the boot sector is damaged. It's a very small download at close to 6 MB.
TuneUp Utilities 2008 won't find files in case the HDD is formatted. Some good recovery apps are fileScavenger and R-Studio. RecoverMyFiles is also a good option.
