Windows No Longer Sees Partition On Second Drive

Overview:

I have two hard drives. Both are Western Digital.

The first one had drive had partition C and H. Naturally the C drive is the boot drive.

The second Drive has partition E, F and G. This drive is less than one year old.

I was attempting to open a file from partition F from the second drive and then all the sudden it frozed on me. I could not even do CTRL-ALT-DEL to get to the task bar.

After waitng a few minutes, I finally decide to shut it down via turning the power off.

I rebooted and all was fine until I notice that my second drive was not showing up at all via Windows Explorer. None of the partition showed up.

So I then shut down and rebooted. Went into my bios setup noticed that I could see that the second drive is being read.

So I exit the bios and rebooted.

After reboot, I was able to see the second drive which has partition E, F and G.

Now I am able to see the files for partition E and G in which I am able to see all the files there. Howefver, partition F does not show any files. In fact, when I click on partition F, it said that this partition is not formatted and ask if I wanted to format it. Naturaully, I clicked no.

I ran my Casper 5.0 program to see the partition and according to the results, it indicates that the F partition has 100% free space.

I'm afraid that I lost everything on that partition but I am posting here to see if there are other methods to check the partition or why it's not working or a possible solution.

The F partition has all my work on it and I really like to see if I can get it back. I do have a backup but that was 4 months ago.

Thanks for any help you may provide.

All the partitions do appear in Win XP Prof disk management and say that they are Healthy. However, under File System, partition F and G do not show NTFS like the others.
