Recover data from disks
Hi all ! After some 'Reallocated sector count has increased...messages', I decided to buy two new HD disks and installed everything from scratch. Everything now is running without any problems. ...

If the firmware saved in the flash doesn't match the version on the disk, then the NAS will attempt to reinstall the firmware from the flash to the disks. Normally that doesn't cause any problems if the firmware in the flash is newer. If it is older, the downgrade could potentially fail.
Since Netgear just announced that final firmware for 4.2.x systems is 4.2.28, if you install that before you archive your disks, there likely won't be a mismatch. You can also store the firmware image on a USB thumb drive that you archive with the disks. Then you can install the firmware onto the NAS first (putting an unformatted scratch disk in the NAS first, doing a factory install, and then manually installing the firmware you want). After that, power down and insert the archived disks in the original order.
The NVX uses standard linux tools, so you also could mount the RAID array in another x86 linux system if desired.
Yes, but only if none of the old disks are part of the new array.

It's best to label new disks by slot as you remove them, and return them to the same place.
You'd
(a) power down
(b) reinstall all of the old disks
(c) power up
(d) retrieve your data
Then power down again, and install the new drives.
Hi
Am in the situation where I want the existing 4 disks from my NVX to be placed in storage for potential retreival later. I understand that the configuration settings are saved with the disks and that if they're placed back into the same unit in the same drive bays they should boot up okay.
However what's still not clear to me is if, in the 18 months that's past since they were replaced, there have been multiple firmware updates to RAIDiator. What happens then if there is this "mismatch" between the old disk config and the new firmware - too much of a risk or "no worries mate"?
Thanks
