I have a problem with my "old" Hard Disk. It is saying that I need to format it but it has data on it. It was working in my old computer. And I wanted to copy the data to my new computer but after I putted it in my external HDD reader it says that I need to format it. I can see it in the disk management as primary partition but it has no partition type. I cannot defrag it or something. Do you know a way to save my HDD, cause almost all my data is on it.
