Software to test FAT Implementation

Do you know any software to verify a FAT Implementation? I'm writing on a FAT32 Implementation which supports "basic wear leveling" on a SPI-Flash.

Now I want to know if my (binary) Image of the Flash is a "valid" FAT, maybe including a list of the FAT BootArea Parameters.

OS independent, tied to Windows on Work, but have my Linux Machine available.

If you know any software - perfect! Let me know! If not - don't worry, thanks for reading :)
