HI Team!
I hope you can help me gurus!,

Here is my scenario:
1. My partitioned Drive I: lost all the files. I don't know why?
2. Checked properties of Drive I and showed me that it's a FREE storage. (45GB Free of 45GB)
3. Downloaded Recover My Files application and I saw all the files. But I did not recover the files , yet because I don't have the license key. (At least I know that the files are there)
4. When to a friend to copy some files and paste it on my Drive I.
5. Now Drive I' property is used. (44.3GB free of 45GB)
6. Then from my Drive I, I cut and paste it on my extra partition.
7. Now Drive I is free again. (45GB Free of 45GB)
8. Used Recover My Files application again, and the files that it first detected (the ones that I needed) were gone. WHat it saw was the recent files from my friend that I moved from DRIVE I to extra partion.
9. Repeated steps 8. no change
10 Tried using other software. no change.
Huhu.
Questions:
1. Why was the first batch of files gone?
2. Is it possible that I may have overwritten the first batch files with the ones that I copied from my friend?
Guys please help.
Pictures and personal videos of my family are very important to me here.

GOd bless! and more power to HDD GURUS!
