I have a fairly new DE52 (5 drives) and today the bottom three drives are showing red lights and beeping incessantly. But, the drives appear to be working normally.
This is on a Mac system and Disk Utility shows nothing wrong with those drives.
I recall we got a disc with a utility app on it … but can’t find that disc now. Is that something on line or that I can download?
On looking this up I think you may be on the wrong forum as that device appears to be a piece of hardware supplied by “rocstor” who are an unrelated hardware supplier of external storage devices (hdd/ssd). However Rockstor is a company that shepherds the development of a gnu open source NAS software product of the same name which is based on CentOS linux. Rockstor also offers paid support options of this software product.
