Question: Right, it is finally time for me to take action. Namely, the HDDs on my workstation “beep” in a pattern, as if it’s some kind of an alert. It’s not an actual “beeping” sound, like it would be from a speaker, but I can’t describe it. Both drives are in a HD Dock, not inside the PC case itself, so there’s no question that the sound is coming from the drives.
Here’s the exact recording of it:
Answer:First ensure that you do have additional backups that are proven recoverable and readable.
Anything you do or try could cause loss of data. Or some catastrophic failure occurs.
My first thought was power but the HDD Dock does have its own external power adapter per the link you provided.
However, consider that the power adapter is faulty in some manner – heat related perhaps.
Another consideration is the power outlet serving the HDD Dock’s power adapter. Is the power adapter plugged directly into a wall outlet or perhaps some power strip outlet that also serves other peripheral devices?
Change to a known stable power source (outlet) and try that. Try another HDD Dock with its own power adapter.
Key is to narrow down and eliminate possibilities.
As for RAID – unless there are specific reasons for a RAID configuration I would not do so. However, I will defer to those more knowledgeable about RAID configurations and implementation.
