External Hard Drive Corrupt - Need Help!!

I have a backup drive of files that I just use to backup random installation files, and school portfolio stuff etc. I went to open it today because I saw a different file size than what I was used to seeing and I saw this in a few of my folders.



Is there any way.... to restore this information or is it gone?? Some of the data on the drive appears intact but then there are folders that look like this!

Any programs in Windows or Mac that anyone could recommend to potentially solve this problem would be greatly appreciated. I currently am not touching the drive hoping that someone can offer me some advice. I already ran a Disk Utility on it and it said th drive needed to be repaired. After repairing it which took over 10 minutes, the drive still looks the same way.

I have a Western Digital MyBook 500 GB drive formatted in FAT32.

I have Drive Genius 2.

 

Thanks for the quick reply!!!!

I guess I'll let this Data Rescue run and see what it comes up with in 16 hours when the scan is complete. I have another drive (1 TB) that I use for Time Machine backups to restore files onto should it find anything.

I should probably almost consider duplicating this drive should it recover most of everything just lost. I have enough space on the Time Machine drive to do so right now.

Let's see what happens first though through Data Recovery. If I have to go and check out any of the others then I'll try those if this one doesn't come through.
