I believe I may have expressed myself incorrectly earlier when I mentioned mounting /boot_flash.
In fact, the mount operation does fail. Please accept my apologies for the inaccurate information.
Below, I will outline my actions and their results. I’m confident this will help you understand the current state of the NAS.
RAIDar does not display the NAS model or serial number.
This information was not shown before and is still not displayed after all the steps described below.
For the recovery process, I am using only a single disk. I understand that it is required for the OS.
For today’s experiment, I removed all partitions from the test disk and started from scratch.
I also cleared /boot_flash.
Unfortunately, I do not have enough experience to properly interpret these results.
