cpqDaPhyDrvBadRecvWrites counts write errors that occurred while the controller was performing Automatic Data Recovery, copying data from another drive onto this physical drive, during the reference time window. Since a write error during this recovery process stops the recovery, a nonzero value indicates this particular target drive has failed and cannot accept the recovered data. As an example, if an admin swaps in a replacement drive and this counter increments during the rebuild, that specific replacement drive itself needs to be swapped again.
