Synology has confirmed a known system issue caused by flawed flash memory chips. This issue can occur when users reboot the DiskStation; the unit will not restart and the blue LED light will blink continuously. This issue does not affect data stored on the DiskStation and will not result in data loss.

The affected products include DS1512+ and DS1812+ worldwide, and DS212j for Asia shipments only. The best estimated quantity is 480, 120 and 700 units respectively and most of them have been returned or are on the way to Synology.
