"DDB18 power is out of normal range" error (#18126676)

Hi Mark you should edit the thread title (i.e. subject of first post in the thread) to include your current case number. That way if a NetGear support representative comes across this thread it will be easier for him/her to help you.

Also when did the unit first start experiencing issues? If NetGear approves a RMA for a new unit, if possible (close enough to purchase) it's best to exchange it via the reseller for a new unit rather than a refurbished one. If the issues started close to the purchase date they should have given you this advice.

My first unit shut down with no explanation and then would not boot.

It wouldn't even go into the boot menu?: http://www.readynas.com/kb/faq/boot/how_do_i_use_the_boot_menu

The second unit upgraded from .15 to .19 and froze (it seems that you can't upgrade from .15 to .19).

There is a bug fixed in 4.2.20. System > Update > Remote or automatic updates would have prompted you to update to 4.2.16 then to 4.2.19.

I'd recommend 4.2.20-T40 (http://www.readynas.com/forum/viewtopic.php?f=51&t=57193) which appears to be very close to a production release.

So support cleans up the mess only to find out that now the unit won't expand the volume after I exchange my hard drives for larger ones.

Often that can be due to a disk not syncing properly for whatever reason. If this is the case it shows up in the logs zip file (Status > Logs > Download all logs). Did they check for that?

Well, guess what, I get a "DDB18 power is out of normal range [expected: 1.80 current: 1.90]." message every 30 minutes. From what I read, this is a hardware issue and guess what...I get to go through the RMA process.....AGAIN.

Ouch! That is a bad run. Hopefully NetGear support can get this sorted quickly.
