2.2.7 FE READ UNCORRECTED BLOCKS DESCRIPTION
This ioctl call returns the number of uncorrected blocks detected by the
device driver during its lifetime. For meaningful measurements, the
incrementin block count during a specific time interval should be
calculated. For this command, read-only access to the device is sufficient.
Note that the counter will wrap to zero after its maximum count has been
reached.
