ReadNAS Pro 6 stuck on 'ReadyNAS' when booting
My ReadyNAS Pro6 isn't booting and is stuck on the logo. I have tried the reset button but I don't even think it is getting to that point. I am about to go through and disconnect and reconnect as m...

Any tips on that sort of swap would also be appreciated.
Start with a test install using a single disk in slot 1. This disk will be reformatted, so make sure there is nothing on it that you care about. No need to worry about the compatibility list, any SATA disk will work for this.
After you've confirmed that the test install worked, then power down the NAS and move the disk to slot 2. Power up, and confirm that the system boots with the disk in the slot. Repeat this process for slots 3-6.
Then update the firmware to match what you are running in the old NAS. If you aren't sure, then just install the newest firmware. That would be 4.2.31 unless you converted the NAS to run OS-6.
Once the firmware matches, then power down again, and migrate your existing disks to the new NAS.
When the new NAS is up and running, then you could consider replacing the power supply and using it as a backup NAS. If you decide to sell it for parts instead, then I suggest selling the drive trays (with the screws) separately.

Usually that indicates that the power supply has failed. It can be replaced - Sandshark can give you some guidance if you need it. You can find them for ~ 100 $USD (or less). Stock supplies usually need a 24-pin extension and more MOLEX connectors, but you can also find some PSUs pre-modified for ReadyNAS.

If you are still using 4.2.x firmware, then you can get a replacement Pro 6, Ultra 6 chassis, or Ultra 6 plus.
OS-6 platforms are also possible- RN316,RN426, RN428, RN516, RN526, RN528, RN626, RN628. Even if your NAS is still running 4.2. firmware, the array can be mounted read-only in the OS-6 platforms. The OS-6 platforms would be somewhat newer, as Netgear stopped manufacturing Pro and Ultra models back in 2013.
A less expensive approach is to get a 6-bay USB chassis and connect that to a PC. Then you use either Linux (including the Windows WSL package), or RAID recovery software to access the files.
