I have a 2tb External Hard Drive WD My Book.
I let an technician check my external, he said that my HDD Enclosure must be replaced with a new one so I bought one and let him changed it for me but when we put it in the computer he said my External Hard Drive has a bad sector maybe because of my last HDD enclosure. He told me the files are corrupted and I must reformat it. I explained to him that the files are very important so he did gave me a program called file scavenger, Tried but fail. I look up in the internet and tried using Recover my Files, Test Disk and wondershare Recovery with no avail.

A friend of mine told me I must Quick Format it to access the data, so I do what he says and told me to use Recuva to recover my files.
I waited for 30 hours and saw the results and look at this

and

Nothing, the results are useless if you want to see look at this images

The files are really important to me, anyone who is good/expert at this please help me, you will have my gratitude in life. there is 3 years worth of research here

Well you should be able to restore most of what's in the green however the paths & file names are gone because the quick format erased that information. As far as I know of there is no getting that back (unless you have an image of your drive backed up) but that doesn't mean that you can't recover the files.

hmm let me see here, Those files are not my concern I appreciate your help but those files are insignificant for those files I really want to restore. Are there programs or method that can give me a deeper or better results

I'm not following you. The files have strange names because the new file system doesn't know what they where called in the old file system before you did the reformat. However the data is still there and can be recovered using rescuva until the data is overwritten. BTW since you don't have the old file system anymore then windows is going to think that the sectors those files are on are available and therefore could overwrite them at anytime. So it's simple, try to recover what's there (no matter what they are called) that's in green & rename them to whatever you want. The data is there but the names are not.

No that thats not it , My files are thousands and they are 1.5tb thats only 16gig, I dont have those kind of files and I may say that does files are to deep in my system. I dont know that they exist while those files I am looking are somewhere hiding dude help me

Well I don't really know all that much about file recovery except that it is usually very expensive with not really any guarantees. Since rescuva is free it might not be very thorough. I'm sorry but I don't have anything else. Perhaps someone else will have something.

Please be informed that installing new programs may overwrite files waiting to be restored.
anyways, I used "UnDelete" to recover my files when I have similar issue.
