Just bought 2 diskless Pro 4's and installed 3 WD1003FBYX Hard drives in each one and setup a RAID 5 array and updated to latest Firmware - v.4.2.20. Everything went smoothly on both units. Rebooting after F/W upgrade showed the new firmware version correctly. I then proceeded with shutting down, adding a 4th WD1003FBYX drive in, then booting up and adding it as a Hot Spare. I proceeded with a reboot and I'm pretty sure both units rebooted fine at this point (or perhaps 1 unit got stuck on "Booting" at this step, but I know the other rebooted fine). I am now at the point where both units power up and get stuck displaying "Booting . . .". I've let them sit for 15+ minutes and they stay at "Booting . . .". Both units will immediately shut off if I just tap the power button. One of the units has the LED's on the Ethernet port (LAN 1) lit up/blinking - even when the unit is powered off, the LED's on the other do not light up.
Working on one unit at a time (the one with no LAN port lights lit), I first tried pulling the 4th HDD (the newly added Hot Spare) and powered it back up -> same result - stuck at "Booting . . ." I next tried to do an "OS Reinstall" using the reset button on the back of the unit. Tried a few times and as soon as I press the "reset" button to choose the "OS Reinstall" option the display goes to "Booting . . ." and hangs. So then I proceed with the "Factory Default" option via the reset button - same issue -> stuck at "Booting . . ." with no LAN Port light activity and no RAIDar detection. I've just now initiated the "Memory test" via the reset button and it is running it's test. It has been running 40 minutes with no errors found.
I have not done anything else to the second unit (the one with the Lan 1 Port LED's lighting up). It's currently still sitting stuck on "Booting . . .".
Any ideas? Is there a problem with F/W v.4.2.20? Should I try to reinstall the F/W via USB flash drive or TFTP? If so, I need to find those instructions for this model.
We're not very happy with this. If this isn't quickly resolved we'll likely return the diskless units and move on to another make and model NAS.
