Seagate ST4000VN000 6G SATA drive SC44 firmware manufacture current allowance speed default set on 1.5Gb/s even its capability=6Gb/s. The PL firmware phase 17 or later can not work with 1.5Gb/s SATA speed. This issue can be solved by manually configuring drives to SATA 6G mode by ‘Seagate SATA HDD Speed=6G’ function on the Advanced Configuration.
