ReadyNAS Duo failure
I am unable to access my READYNAS. I am guessing it is some sort of internal power failure. The external 12v supply seems to be OK when tested with a meter but the blue power light on the NAS is inte...
Are you testing with a meter under load or unloaded? Testing unloaded is close to useless. You need to know if the power is drooping when the drives try to spin up. If it is, it could be a bad supply, a bad drive, or something else in the chassis; maybe as simple as a broken solder joint on the power connector. Assuming your volume is RAID1, have you tried booting with just one drive, and then with just the other one? How about with no drives? Does RAIDar show the NAS with a "No Disks" status?
Thanks. You were exactly correct. I tested the PSU with a load and it was crowbaring as soon as the load was applied and then reseting again and repeating the process. Hence the flashing blue power light on the NAS. I was able to get a new secondhand PSU from the local computer shop and hey presto the NAS sprang into life. I thought that the constant crowbaring of the old PSU may have fubarred the NAS but fortunately not. +1 to Netgear
This is the second time I have had to replace the PSU. I guess that the NAS must be quite demanding on power or that the PSU's are all rubbish nowadays.... -1 to whoever makes Netgear's PSUs!
Cheers, Robin
We call that "motorboating" (think about the sound a boat makes skipping over waves). Glad it was just the supply. Drives today tend to take less to spin them up than ones available when the Duo came out, so it is odd that it has gone through two supplies. Do you have the brick well ventilated? One of the worst places for one is on a carpet. You are basically insulating one side. Also remember that the NAS does still draw a small amount of power when it is "off", so don't let it get really hot then, either.
I bought a couple of units used without the brick and substituted ones designed for security cameras. I find they tend to be better regulated than some others (and, of course, a bit more expensive). Almost all of them, including genuine Netgear, are made in China.
