Folders in HD turned into clusters
Hello, I have external WD 1TB hard drive. One day 3 folder in my hard turned into 32KB files. I've red some articles and learned that it might be a cluster. Dispite the fact, there was about 200GB data in these folders, hard drive's used and free space is same as it was. So I think my data should be somewhere in the hard drive. I've googled a lot, but I didn't found why my data turned into clusters. I want to know how to recover my files of these 3 folders. How to turn these clusters into folders with my data? Thanks.
