After an Abnormal System Shutdown, whether the abnormal shutdown occurs because of power failure or not properly powering the down the NAS, File System Check will "automatically" run on the subsequent "power-on". During this period the status indicator LED on the front of the NAS will flashing "orange" and "shares" will NOT be accessible until the File System Check has completed. This is "NORMAL" behavior and is done to ensure that the File System is healthy and does not contain errors (minor or major) which can affect data integrity in the short or long term.

NOTE: File System Check is only available on NS2300N SR1 (or higher) Firmware and NS4300N SR5 (or higher) Firmware. The File System Check Progress meter will progress to 95% within the first few minutes and remain at 95% until the process is complete. Again, this behavior is "NORMAL".
