Disk Not Formatted Error & RAW Drive

When you get the popup dialog box which shows disk in drive is not formatted do you want to format it now, you can find its file system might also be changed to RAW. In this situation, the system cannot recognize the file system and the disk drive will be inaccessible. The data stored on the disk will accordingly be unreadable since the disk needs to be formatted to a regular file system that can be recognized by system. This is also the reason why Windows pops up dialog box to prompt you to format the disk in order to make it work properly again.

The best time to perform format on the RAW drive is when you are sure that all data has been recovered.
