FAQ

Q: Does MB521SP-B support the new SATA 3.3 / SAS 3.0 Power Disable feature (PWDIS)?

A: The MB521SP-B does not support the SATA 3.3 / SAS 3.0 PWDIS feature. If you install the SATA/SAS HDD/SSD with PWDIS in MB521SP-B , the drive will not spin, and the system won't detect the drive. See the list below for known SATA/SAS HDD/SSD with the PWDIS feature.

Known SATA/SAS HDD/SSD with Power Disable Feature (PWDIS)

While we recommend to avoid using the SATA/SAS HDD/SSD with PWDIS, you can use the methods below to disable the PWDIS feature physically if you already purchased the drive:

Method 1 – Using the Molex to SATA adapter or cable to disconnect the power to Pin 3 of the SATA power connector.
