Part 1. Restore Data from RAW/Inaccessible SD card 

The hard drive which has not been formatted by the NT file system, such as FAT and NTFS, is called the RAW hard drive. When your drive becomes RAW, you cannot access it. Meanwhile, its capacity used space, and unused space will all be shown as "zero". That is to say, all data originally saved in that "RAW" disk are lost. You can neither see them nor transfer them to a safe place for further use.

But a third-party data recovery program can access this RAW drive and get back data before formatting. EaseUS Data Recovery Wizard is an ideal choice for recovering RAW drive data.
