In most cases, this issue is related to the internal cache memory of the hard disk: the data got corrupted when it read back from the disk surface because of an issue which is independent from the disk surface itself (so there are no bad sectors, no surface / head problems).
However, in some cases it may point on issues with the data cable, as this may cause communication problems.
Some other attributes (187 and 199) may also confirm this - as they record different communication problems. As Alan-0000 wrote, the actual numbers in the DATA field not really visible, but it seems this is the case. I suspect the text description on the Overview page also shows communication problems.
I'd recommend to check http://www.hdsentinel.com/hard_disk_case_communication_error.php
for more information about this situation.
