This log entry does not make any sense. Hex-conversion of the large 
values suggests that the drive returns garbage bytes in the error log:

  Num ErrCount        SQId  CmdId Status PELoc LBA NSID   VS
    0 0xc000000330100    0 0x0000 0x3101 0x000 0x100000000000300 50 0x01

Other values of the output do not show any sign of trouble.

There are also other drives with a similar issue, see
