I've a big issue with my R4.

My R4 can not connect to PC two days ago, and drive activity LED of slot 3 was dark.

then i replace a new disk to slot 3.

after that, the utility tells me can not rebuild because "There is no PD of adequate capacity".

i don`t know how to do now, please help me!

Hi Chen,

It looks like drive 3 is not detected on the unit.

Can you follow the below steps and update the status?

- Unmount the volume.

- Power off the unit using power button.

- Remove drive 3 from the slot( top drive is 1).

- Power ON the unit without drive 3 in the slot.

- Wait for few minutes and Insert the drive 3 to the slot.

Kindly check the drive 3 on Promise utility and update the status.

I tried these steps, slot 3 is still not found, and after Power off & Power On, the utility said "device not found".

after reboot my pc, the utility works, status as same as yesterday.
