What is the file system of your external hard disk? Is it fat32, or ntfs? What if the external hdd suddenly becomes raw? Raw means not format to a certain extent. So it means that we can not use the external hard disk with raw file system, and we need to format it in we want to keep using the portable hard disk drive. It is so terrible. For instance:
My external hard disk shows raw file system when I check its disk properties. What’s more, both the used space and free space are 0 byte. How strange. I have stored some video files such as movies on it at the previous time. Then we I try to open the external hard disk, system prompts me to format it before I can use it. What should I do? How can convert it to fat32 and how can I recover videos and pictures from unformatted external hard disk drive? -Jesse
Do you have any idea how to convert the raw external hard disk to fat32? We can not complete the conversion when the external hard disk is in raw file system trouble, but we can format it and then change the file system of external hard disk to what we like, such as fat32, ntfs, and so on. So should format the raw external hard disk in order to convert it to fat32.
After formatting the raw external hard disk, there is nothing still saved on it. What should we do if need to access files saved on the external hard disk at the original time? As a matter of fact, if those contents are useful or precious, we can perform data recovery when it is raw file system.
