To provide additional information regarding my problem, I initiated a data transfer from the MyCloudMirror to a computer that took 60 minutes to complete. To review, the drive stops responding after about 60 seconds after the data transfer starts when I am writing files to the drive. When I am copying files from the drive, it never stops responding and continues to transfer data, in this case, for an entire hour. It still makes me think there is a sequence of data bits when writing files to the drive that it doesn’t like and makes the drive stop responding. Never in my IT career have I ever heard of a problem like this occurring. Has no other owner of a MyCloud Mirror seen a problem like this?
As a follow-up to this issue, I have acquired another MyCloudMirror as a replacement for the misbehaving MyCloudMirror. Unbeknownst to me at the time of purchase, the replacement drive runs OS5; whereas, the problematic drive runs OS3. I migrated the two hard drives from the old unit to the new unit, in which I was informed the drives were of a RAID1 configuration taken from another unit. I resolved all issues, created the necessary user accounts and made sure the shares were configured correctly. I found a slightly newer version of the OS5 firmware and installed that. I then performed some fairly long and large data transfers to the MyCloudMirror in which the new drive never stopped responding and stayed alive on my network. Changing one variable, leaving everything else the same, indicates the old MyCloudMirror drive definitely has some sort of a problem when it comes to accepting a data transfer. I can read from the old MyCloudMirror seemingly all day long and the drive never stops responding. As an experiment, I installed two WD 500 GB drives in the old MyCloudMirror to see how it would behave with different drives. I successfully created a RAID1 configuration and created one share. When I attempted to transfer some large ISO images to the drive, it again stopped responding with 2 minutes. That means the fault is not with any hard drives and the fault is with the unit, itself. I think I am going to list the faulty MyCloudMirror for sale on eBay with a full explanation of the problem in the event someone wants to perform a little troubleshooting on it. Still seems strange that I was able to obtain the only MyCloudMirror in existence that can’t stay alive during incoming data transfers.
Your MyCloudMirror may be experiencing a hardware-related issue, possibly overheating, power instability, or a network controller failure. Since you’ve ruled out firmware and network configurations, try these steps:
- Check Device Temperature – Overheating can cause sudden freezes. Ensure proper ventilation.
- Use a Different Power Adapter – A faulty adapter can cause instability.
- Test with Direct Connection – Bypass the switch and connect directly to your PC via Ethernet.
- Monitor Logs (SSH Access) – If possible, enable SSH and check system logs for errors.
If none of these work, it’s likely a hardware fault, and replacement might be the best option.
