ReadyNAS Pro 2 doesn't detect new disk

Hi all, My good ol' ReadyNAS Pro 2 just indicated a few days ago that disk #2 had failed (Hitachi HDS722020ALA330 1863 GB). I've replaced it (hot-swapped) with a similar one, a brand new Hitachi ...

Does the original disk in slot-1 boot (with slot 2 empty)?

Since I couldn't afford to lose too much time on this, I bought a replacement (Synology DS216+II) and put the ReadyNAS on the side of both my desk and my thoughts.

But since you asked, I gave it another try, just to be sure. And... can't believe it. First, it booted perfectly with the original #1 disk, and I could access it via web-interface. Then I (hot) inserted #2 (which had been marked as dead), and... and it's now re-syncing!...

I don't know what happened during that time, I only had the ReadyNAS sitting (completely unplugged) on my desk. Did it just need a bit of rest after 5+ years of uninterrupted service?... Puzzling...

Et voilà. A few hours later, the #2 disk has been synced, and all's green and normal again.

Now I just have to find a use for this device again... Backup of the backup's backup? ;-)

Well you are in an ideal situation to upgrade your Pro 2 to the latest OS 6 Firmware, which has many more features

Backup before doing any of this as everything will be deleted including settings

First upgrade your Firmware to 4.2.30

Next update your Bios by uploading this file to your NAS http://www.readynas.com/download/addons/x86/4.2/BIOS_Update_Package_0.5-x86.bin

Download PREP4TOR6_0.1-x86.bin

Upload it using the ReadyNAS web gui firmware update, but do not reboot afterwards (avoids the need to do manual factory resets)

Download R4toR6_latest.bin

Upload it using the ReadyNAS web gui firmware update

After you upload the addon/firmware and reboot, it will update the firmware and start a factory default.
