ReadyNAS nv+ won't power up after outage. Power Supply Problems?
Hello My ReadyNAS NV+ (Product: ReadyNASRND4000, Serial Number: 23J3027700C11) was originally purchased in November 2010. In June 2016 I had a problem with the power supply: The NAS wouldn't start u...
Yup. You can test that it turns on the supply with it disconnected before you do it with it connected. You'll know the supply came on because the fan will run.
If it works, you likely won't want to leave it that way, but it's a way to get the data off the NAS.

Well, according to this page there is. (I realize that the pictures are of the NV+ V2 board.) It has a link to a product sheet on the port multiplier.
So far I haven't found a schematic of the NV+ board. Surely there must be one out there...
There's a site that shows a project that does what I want to do using a Raspberry Pi and which uses a USB hub and USB-to-SATA adaptors to connect the four HDDs. I'm looking at that now. Seems questionable. But then the Pi has no SATA connector, whereas the Wandboard does. And the NV+ has the multi-SATA backplane and presumably a port multiplier chip. Of course, I'd need a schematic and help to make them available to the Wandboard. I'd need to fire somebody's interest in the idea...
Netgear has not published any ReadyNAS schematics, so anything you find would have to be reverse engineered.
The NV+ V2 is a Netgear design, where the NV+ is old Infrant. They are very different designs.
Even if the NV+ has a port multiplier, it probably has a 2TB limit per drive. Otherwise, I think Infrant/Netgear would have put out a version of the OS that supported >2TB drives.
