Windows 7: MFT and MFT mirror damaged and can't be repaired.

MFT and MFT mirror damaged and can't be repaired.

I've been having problems for some time now, mainly my PC getting slow and then freezing and I had to restart it. I checked for viruses and such, there was no sign of any.
Later on(all this happened in the span of like 1-2 weeks) it froze again, but this time it had problems turning on. Turned out it had something to do with the registry, one of them was corrupt or something along those lines. I did fix it, or at least I think. I know how to google and look for a way to solve my problems, but I still don't really understand the problems themselves.

My friend warned me to still be careful, even if I did fix it. These things started happening again, mainly my PC just slowing down and freezing. But I did notice after to "fix" that my PC overall was slower, slight freezes and I noticed that Photoshop(which I use a lot) was way slower than usual.
I got concerned, checked the task manager if something new/weird was using my my RAM, but nothing. I checked for virus or anything of that sort, yet again nothing weird. I started to get paranoid, so I used "HD Tune" to check how my HDDs are doing, I did not want to lose any of my stuff. No problems at all, no bad sectors. I had no idea what to do, everything seemed okay, even if it obviously wasn't. Yet again it froze, I restarted the machine, problems arose again.

Finally I got it too boot up and work. I check "My Computer" and I can't see how much GB I have used and have(the usual things that show) on my D: drive. I press it expecting an error message, I got "D:\ is not accessible disk corrupted and unreadable" (now, after the stuff I did I get "D:\ The parameter is incorrect"). I tried different stuff, including using TestDisk and "repair MFT" and I got what's in the title basically. I did try the "chkdsk" thing, for C: it did "work" in the sense that it checked the files(or whatever this option does). When trying to do it with D: drive I get "The type of the file system is NTFS.

Corrupt master file table. Windows will attempt to recover master file table from disk."
Doing it in either with CMD or just letting it do it when the PC boots, both times the same result.
I also tried "HD Tune" again just now and it said that the health is Ok and only 0.1% damaged sectors. The weird thing is that C: is working, albeit everything is slower, while D: seems dead(they are both on 1 HDD).
I do plan on formatting the HDD completely, but still is there some way fix the D: drive. I heard of drive cloning and such, but that won't work since I have another HDD, but it's only 500GB(while the corrupted one is 1TB, even if I choose specifically D: to be cloned it's still 700GB). I also thought of file recovery software like Active File Recovery, but just scanning the drive would take more than 200 hours(that's what it said), then if you add recovering the files it would take even more.
So is there anything I can do to fix D:, get only my most important files to my 500GB HDD and then format it?
My operating system is Windows 7 64bit Home Premium.
The HHD is: WDC WD10EAVS-00D7B1 ATA device



Thank you in advance! I really do appreciate it!

Hi NikolaiT,

Welcome onboard.

When Test Disk has said MFT cannot be repaired, the only option left is to recover the data using PhotoRec.

PhotoRec - Digital Picture and File Recovery

Since your System HDD is impaired, I would recommend running PhotoRec from a bootable pendrive and recover the most important data to your 500GB external drive. Better if you have a 1TB drive so that you can copy all data.

(Create a bootable MS-DOS pendrive with Rufus and dump all the TestDisk files into the root folder. Boot from the pendrive and run photorec.exe from it with your 500GB/1TB external plugged in.)

In the absence of a valid MFT, Photorec will try to reconstruct the files ab-initio from its attributes and hence what you will get is only a bunch of files without the original folder structure and original file names.

Depending upon the severity of bad sectors, the scan may take time. There is no escape and you have to allow the scan to complete even if it takes one week. As it scans, you will see the number of files recovered and copied.

Note: If PhotoRec also fails, the author recommends trying Getdataback or Zero Assumption Recovery. Both are paid software.

Having said that, the best recourse when your System HDD is obviously failing, is to use ddrescue in SytemRescueCD to clone your drive and try data recovery on the cloned drive. https://www.system-rescue-cd.org/Sys...cueCd_Homepage And ,yes, it will require a new HDD larger than your system HDD and again it may take a long time to clone.

If only you had backed up all your important data to another external HDD on a regular schedule, you could have saved all this trouble. Is itn't?
