thank you so much for your replies and your help, you won't believe how much i appreciate it.
so to Mr
Pauly : the crash it's not due to a power out.
to Mr
BIGBEARJEDI : yes my computer is custom-built, and i built it my self, it's been 5 or 6 years ago.
for the datas , I have tested my external hdd on my laptop " my laptop also run windows 7, and it's clean" . I have tested on my laptop, to see if it's matter of OS but the same issue persist.
>>>Sounds like a language issue here, but you need to test the ACTUAL HARD DRIVES themselves, not the data contained on them. Use the testing procedures I outlined in my previous post. And it's essential to check all 3 of your drives, not just the Windows C: boot drive. Most likely you'll have to go to the WD.com website to download the HGST drive diagnostic as you have a Hitachi, and the SEATOOLS diagnostic won't test that drive.<<<
so if i can reinstall windows like you suggested*, yes i can, and I have an authentic- genuine windows. I didn't do it until now , because i'm trying to recover some data on my desktop windows. and if it work, then it will work on the external hdd- that I disconnected afraid to lose other data.
>>>Thanks for providing that information. Since you do have a self-built custom rig or system, it will take much more work to perform a Windows reinstallation, which is part of the reason you are avoiding it I am sure. Since you have no Factory Recovery Discs or Recovery Partitions, you'll have to reinstall your retail Windows from your disc, and then re-download all your drivers (or from the original disc that came with your Foxconn Motherboard when you purchased it), and that's usually 2-3 days or more if you have to download and reinstall all the drivers. I'll address the data recovery issue of your boot drive below. One other thing to note, is that if your Hitachi boot drive has failed or is failing, and your probelm is NOT from a virus, your attempts at using Recovery software will further damage the existing data (such as your photos), and decrease the chances of you ever getting it back from that damaged drive.
Non-destructive testing of that drive is IMPERATIVE to know the answer to this question.<<<
The mean raison i think is: I had the idea to install a program to manage my internet bandwidth, the program is "SoftPerfect Bandwidth Manager". So when i did and installed it, the program didn't want to work properly, then I googled for solution,the solutions that I found was that my firewall block the program, and yes when I had checked my firewall, I found it locked with no chance to communicate through.
so i had the bad idea that had been suggested in many website, is to delete a file in "hkey_local_machine" .So I have done this, without create a restore point, then I restarted my windows to see if all what I have done, work well.
but my my windows crashed, and after recovering windows, I found that my data were corrupted. and my external hdd was connected so it also had the same issue . My data still there but corrupted with 0 bytes, like the photos I posted previously.
>>>That makes sense to me. Doing manual Registry "tweaking" without knowing what you are doing often produces unpredicatable and disastrous results. Those results we call "WINDOWS CORRUPTION" in lay terms, in technical terms you have damaged your Windows Hive files. It takes expert level skills to recover from this. Those bad results also mimic virus damage. So, to determine whether it's a virus or a windows corruption problem, you must start with the testing and validation of your hardware; specifically with your hard drive (C: boot drive) first, then the RAM. If you don't take this testing step you are just wasting your time trying to figure it out and have any chance of recovering your lost data on that C: drive!<<<
my conclusion is I think that a VIRUS has done this. and if it's really a virus that has destroyed the data. there is a hope that I recover my data ?
>>>As, I said, your conclusion is probably faulty, at this point, until you perform the necessary hardware testing I mention above you cannot jump to that conclusion. Also, you haven't mentioned that you've run any virus scanners that detected a specific virus. Since you can't identify a specific virus, or something similar, you are only guessing as I said.<<<
there are programs that can do the work ?
>>>Yes, there are programs that can assist with data recovery, but it takes many years of experience (20+ yrs.) to be proficient with them. Some of the ones I recommand are:
1.) Testdisk & Photorec (ISO Linux)
2.) Recuva from piriform.com (Windows)
3.) GetDataBack(Windows)
#1 & #2 are free; #3 is free to try and if it finds your photos/files they charge you $60 on a Credit Card to actually recover them, assuming you know what you are doing.<<<
and also like you suggested, if nothing work for me , I can send the drive to "data recovery". but can I trust them for my data ? and what is the procedure ?
>>>Yes, you can send out to professionaly data recovery. You can google both of these companies, they are in the U.S. only, so if you are outside the U.S. there will be substantial increased cost to ship Internationally. Here are the only 2 Companies I have used for this and trust implicitly with my data as well as with my client's data (I have personally used both):
1.) BEST BUY GEEK SQUAD (Google Best Buy and use Store Locator to find closest store to you).
2.) KROLL ONTRACK (WEBSITE HERE:

For your information, data recovery starts at about $250 US at both places. The procedure is different for these two. For Best Buy Geek Squad it's best to find a store and walk in there; you'll have to fill out paperwork and data disclaimers and sign the forms. They will then ship to their Recovery center in Mempis, Tennessee. For Kroll Ontrack, you'll have to call them and ship your drive to them in Minneapolis, Minnesota. I don't know if Best Buy Geek Squad will take your order over the phone or from outside the U.S.; never tried it.
After you send in your drive, they will perform a level 1 recovery which takes 3-6 weeks typically.
<<<BBJ>>>
and thank you again / BIGBEARJEDI your answers gives me hope, and you are like a real JEDI for me
