MBR? 2 Partitions, 1 ok, 1 not ok. How to Recover Data?

I have 3 hard drives currently installed in my computer. 2 are seagate sata-3g interface, easy. I pulled out an old IDE hard drive, a samsung 300GB. It's set to slave. On the post and boot screens, and the BIOS, it indicates the IDE drive is FAT32. Within Windows 7, it says that it is not formatted. It even said it was RAW.... that's not right! So I downloaded EASEUS Partition Master Home Edition and ran it. Now it shows Drive 3 as being split into 2 partitions: first partition (named "Ho" shows FAT32 formatting). The second partition (named "applications" shows no formatting). At one point I had this as my main drive and set my default settings in my O/S to install all my applications in that partition. I set all default folders to point to that drive at the time. I wanted to keep my O/S on one partition and all my applications, photos, user data, etc, on the other, so that when I defragged, I really only had to keep up with the applications partition, since I never changed anything on my main partition. Here is a screen shot:

I would like to save the data on the applications partition. I tried a few tools that "dug" up my old drives and I did get a few logos, application graphics, splash screens, etc, but really not much of value.

Any recommendations on how to recover lost data on Windows 7? I also would like to convert all drives to NTFS, so I can just run CONVERT drive from a cmd prompt, right? Thanks...

This 3rd IDE disc is giving me the most trouble. I have another question. In my BIOS, under SATA settings, I have it set to AUTO. Should it be set to something else, like ALHC (or whaetver that is) or RAID? I am not really running RAID drives here, but I never heard of the other option, so I was curious about it. I also haven't run SATA and IDE together like this, and since it's Windows 7, just wondering if there are iissues regarding it.

Thanks

That's the blinding obvious isn't it?

If you see, it shows only 31G on that 300GB drive. It also doesn't show a drive letter. Both are "*" marks, which indicate it isn't just the bad second partition.

It seems this is a master boot record issue? Yes/no? Is it possibe to rebuild the FAT table or MBR or whatever, under the Windows 7 O/S?

whs said:

On any drive with shadows you can recover data with Shadow Explorer.
ShadowExplorer.com - About

He can't read the partition, he's not just missing a few files. Shadow copies only help you when you don't have problems reading the rest of the drive.

I have used a few data recovery tools, the two best i have found are "BackToLife" and "Easy Recovery Pro"
