Hello Heitor,

Sorry, but in this case, this is a checksum error (the checksum in the
header of the block does not correspond to the checksum of the actual
block data that was read) and not a number of EOF marks error.  The EOF
mismatch is basically a synchronization error between the volume and the
catalog.  However, in this case, it is most likely a disk corruption
problem.

Best regards,
Kern
