Ultra4 (OS4) is dead what's the best way to get disks back online ?
Dear All, Not sure what would be the best place for this discussion, but since the easiest way for me will be to buy a new unit I think HW compatibility is the right starting point. A short...
No, the Ultra 4 does not use the supply listed by StephenB, the Ultra 6 and 6-bay Pro models do.
The NV+, NVX, and Ultra4 all use the same power supply, with the pin-out as shown here: http://www.readynas.com/download/archive/pdf/ReadyNAS_PSU_pinout.pdf. I assume the 4-bay Pro's do as well, but I've never had one. It appears to me to be nothing more than a differently wired Mini ITX supply, which is readily available for under $40. The ratings on the one from my parted out NVX are +3.3V @ 8A, +5V @ 8A and +12V @ 7A. It even lists the -5 and -12V's on the label, which even more leads me to believe it's just a specially wired standard supply with the fan removed (even has a spot for the removed fan, and my original NV did have the fan installed.. a 150W supply should be more than enough, and NewEgg currently has a $10 rebate on a $39 one.
Before you are sure it's the power supply, you could do the "paper clip test" on the existing one. The on/off being a "soft" one, a motherboard issue could cause failure to power on, too. The voltages may not be quite right with no load, but it can be of some help in verifying the issue is the power supply. If it is the supply, you can use this info to do a temporary external install of an ATX supply just for files recovery or you could try the Mini ITX one.
