One of the disks in my QNAP NAS failed. But when I insert a replacement (of the same capacity), I get the message, "hard disk failed or unplugged". It is a brand new disk, how can this happen?
-
Your new disk might not be supported by your model of NAS. You can check the hard disk compatibility list on the QNAP website.
-
The new disk might be faulty. It is not unknown for brand new hard disks to be DOA (dead-on-arrival).
-
One of your QNAP drive bays might be damaged.
I can no longer access my QNAP NAS via my web browser. The IP address I’m using is the one which I have always used.
-
Check that the network interface LED light (at the back of your QNAP NAS) is flashing.
-
If the LED flashes red or red/green, the NAS is not configured properly or the hard drive is not ready.
-
If all the LED lights appear okay, you might have to reset your NAS. You can reset your NAS by pressing the “reset†button for 4-5 seconds. This will bring all network settings and the administrator password back to default.
-
Open a web browser and type in http://NAS_IP:8080 and you should be able to access your NAS again.
