Q: Does MB839SP-B support the new SATA 3.3 / SAS 3.0 Power Disable feature (PWDIS)?
A: The MB839SP-B does not support the SATA 3.3 / SAS 3.0 PWDIS feature. If you install the SATA/SAS HDD/SSD with PWDIS in MB839SP-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.
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.
|  |  | |
| Molex to SATA Adapter | Molex to SATA Cable | 
Method 2 – Placing Kapton tape on Pin 1-3 of the SATA/SAS power connector to isolate the 3.3V power, as shown below.

Please contact tech@icydock.com if the problem persists.
Q: I want to see the drive status from the front panel on PC case/chassis. What should I do?
A: There is a 2-pin front panel header(s) on the PCBA of the product. The drive status can be displayed from the front panel after connecting the front I/O wire to the corresponding 2-pin header of the product. For detailed connected methods, please refer to the user manual of the PC case/chassis.
| Drive Status | LED Indication | 
| Power | Solid Light | 
| Drive Access | Flashing Light | 
Note: The I/O wire connected to the PC case/chassis are not included in the product package.
