Hello, friends:
I'm writing this guide so that if anyone has encountered this problem, they know how to solve it. This is an example of a RAID5 in Windows and on Windows, which is what I have and the case in which I did it. I suppose that for other RAIDs, the example should work.
To do this, we need:
- Patience
- Not to have touched the disks after the damage. This means:
- not trying to recreate the RAID
*not letting Windows format or mount them or whatever it comes up with
- not disconnecting them and putting them in an external box: why touch them?
All of this can be summed up in: Put that screwdriver away and keep reading :osvaisacagar:
- The RAID Recovery for Windows program.
1. Start the program and click NEXT.
2. In this window, check the option "one drive is missing" and choose the disks that made up your RAID. In my case, I had a RAID5 of 3 disks of 1TB. I should have chosen the 3 disks, but for some strange reason, it didn't work better. I say it should have because the 3 disks make up my RAID and, therefore, if I knew which ones they were, I would have put them. ERROR
What worked for me was putting only 2 of the 3 disks that made up my RAID5 and clicking NEXT.
3. After that, it will start calculating the affinity between the data that the disks should have: entropy. In the image, since I didn't save the recovery ones, I show one that gives an entropy below 2%. This is no good, the same if it's below 10%. If it's below 10%, even if it shows us the data that was stored in the RAID, everything it recovers will be useless. BE CAREFUL WITH THIS.
4. In this window, it shows us the characteristics of the RAID we have selected to recover, as well as the maximum entropy it found, 0%, so no matter how much you click NEXT, you won't do anything. In case of a low entropy, go back and select another of the disks and deselect another, but they must belong to the RAID. Try until you find the selection that gives you the most entropy. Remember: more than 10%
If we have more than 10%, click NEXT.
5. Here it will already show us the directory tree with all the folders, where we can choose what we want to recover. Even so, I recommend verifying that what is being recovered is correct, because although it shows you the files with the correct size, it may not have recovered them completely and, for example, the photos may appear halfway, or the isos corrupt and so on.
NEVER REBUILD THE RAID WITHOUT CHECKING THAT EVERYTHING IS CORRECT. After that, I don't know if you can go back.
In this image, the same. As it's a fake recovery to show the images, I don't think it's good.
This is MY case. Remember that the data that gave me an entropy of 12% may not be the same for others. Each PC and disks are different.
