I have an old NV+ that I am trying to resurrect. When turning on the NV+ it seems like the power supply and the fan spin up correctly, the disks seemed to power up and sync, and the LED screen at the bottom says that the machine is booting - and starts performing a quota check. However, about halfway through or just after finishing the quota check the entire system shuts down -- power light goes off, discs turn off (strangely the LED screen remains lit). The machine becomes unresponsive until the power cable is removed and reseated. I haven't seen anyone mention a problem like this before, so I'm seeking some help.
I've removed my four disks from the machine just to be safe. It seems like the quota check is completed successfully, but I don't want to take any chances. I placed a scratch drive in the slot one position, and upon booting, the NV plus attempts to install some firmware onto the drive and starts building a table. However, it seems that the same problem happens- the machine will get halfway through building its table or partition, an shut down. So it seems like the machine is _trying_ to start up a new RAID partition.
Has anyone run across this before? I'm assuming it's some sort of overheating problem on one of the components in the machine, but maybe it’s a power supply issue? I have blown out the machine, and made sure that the fan is working, but it might be something more serious. I'd like to recover the data from the four drives, and I'm even willing to rebuild the raid in another form if that's necessary. Just wondering if anybody is run across this, or whether I'm running into a hardware issue, etc.
Most likely, one of the voltages of the power supply is going too low. The power supply is always the usual suspect after the drives (which you have checked), and your symptoms are consistent with that.
If you have an ATX supply you can use, an adapter cable can be constructed to connect it externally ands see if that fixes it. While the internal power connector looks like a 20-pin ATX one, it has a non-standard pin-out, so don't just connect an off-the shelf suppply not specifically for a ReadyNAS and don't just use a standard 24 to 20 pin adapter cable.
So, step one is determining if resurrecting your NAS is a high priority, or just getting the data off the drives to go on a replacement NAS.

In this situation it will
Create a small partition (2 GB) and install the linux and the NAS software onto it
Create a RAID-0 (jbod) data volume on the rest of the drive.
I'd like to recover the data from the four drives,
One approach is to find a way to connect all four drives to a Windows PC (usb adapter/docks or a multi-bay usb enclosure). Then use R-Studio ( https://www.r-studio.com/ ) or some other software package that supports RAID and EXT file systems.
If you are skilled with linux, you could also try mounting the volume manually in an x86 linux system (and avoid the need for RAID recovery software).
Thank you. I'm really just making sure that the data on the drives is recovered. I don't feel confident making the ATX cable by myself, but I did find a replacement power supply for less than $50, which sounds like a good deal. I've ordered it, and it should be here this week. Hopefully that will let me boot the system and make sure all the data is copied off.

It was indeed the power supply. Replacing the power supply with one that I found on Amazon for about $50, allowed the machine to boot and allowed me to reestablish the shares. Looks like the drives are OK.
I am currently copying everything off of them, and will probably retire the unit! Thank you so much for all the help, this is a great forum for support.
I'm glad your data is OK and that I could help. ReadyNAS, including power supplies, are actually quite well made and usually last quite a long time (there are always exceptions). But we tend to continue to use them well beyond when we would retire a general purpose computer, even though a NAS really is a computer without a keyboard or display, and nothing electronic lasts forever.
