I have replaced a failed drive (A) on a client's device, using a WD SATA drive. After I did this, I was able to get into the Web interface (as shipped, no hacks) and format the drive. Subsequently, the interface told me it was synchronizing, although the drives were not mirrored.
This process eventually timed out - at least, I can't access the interface, which was very, very slow to respond prior to this. I have tried resetting the device (per WD's Web site), but am still having issues accessing it.
The lights' flashing sequence is different from those noted on WD's Web site. I see the outer ring light go on and off, then it flashes an arc in each quarter of the ring, each flash being followed by the entire ring lighting again. The inner ring has a short arc lit around the 2 o'clock area. This doesn't change.
The other feature of this problem is that I can't power off from the front button - just by pulling the power cord.
If anyone can shed any light on this, I'd be most grateful.
Thanks,
Des
