I have a DNS-323 HW C1, with FFP installed. When I run the scan disk tool from the UI, it comes back as "FAILED" after about 20 seconds with no other information. There are no amber lights on either disk on the front panel and I'm not experiencing any data issues. I've tried to run the fsck from FFP in "don't fix" mode, but it can't really do anything because the drive is mounted.
Other than pulling each disk and checking it with the manufacturer's software, anything else I can try to see what the issue is?
