ExFAT Checksums Question

Question

Hi,

According to the ExFAT filesystem specification (https://learn.microsoft.com/en-us/windows/win32/fileio/exfat-specification), ExFAT stores checksums of all files and directories in the filesystem.

Is there any way to validate that for a given ExFAT filesystem, the stored ExFAT checksums for all files are correct? The point of this would be to determine if any data corruption has taken place.

Thank you,

James Pedersen

Hi James,

Unfortunately, the description doesn't not mention files' checksums. Checksums are used only for some critical data structures, e.g. directory entry structures.
