ReadyNAS Pro 4 — ERR: Could not properly extract [Resolved]

I started a factory default boot to reset all my settings and wipe the disks. When I next looked at the LCD on the front of the device, it was showing:

It turns out that this message was originally:

ReadyNAS Pro 4 wrote:
ERR: Could not p roperly extract

but subsequent status messages had overwritten the second line. When it reached 100%, the device status changed to "Booting..." and it never changed. I left it for several hours, just to make sure.

Over the next few days, I Googled and I searched kb.netgear.com, and there were few details as to what might have caused the problem, let alone how to fix it. Google kept pointing at this forum, but there were a bunch of people with the same issue as me, who got PM'd by mdgm and their problems magically went away. With other avenues apparently exhausted, I decided I would try this mysterious solution, and PM'd mdgm first.

Within a day my ReadyNAS Pro was working perfectly again. I even received some cautionary advice on the potential pitfalls of my current configuration, which I now have the opportunity to resolve before any damage is done to my data.

I would like to thank the members of this forum for making it exist, the people who reported the same problem as me previously which led me to a solution, and especially mdgm, who gave up a considerable amount of personal time in order to help out some stranger online.

You're all awesome.
