I used a free data recovery tool on a rebuilt drive and was able to get what I needed from it. Thanks so much for the help with this! Lesson learned to make more frequent backups.

@JorgeB No valid secondary superblock. Am I screwed?

@JorgeB It was XFS. How do I tell if it's attempting to emulate disk1? It does give me a "Unmountable: unsupported or no filesystem" message on Disk1's line, and it's set as Not Installed currently. Running that command produced no output, btw.

@trurl Sorry for the delay, Black Friday shipping made my new drive take a bit to come in. Here are the new diagnostics. You are correct that it currently shows as unmountable when running off of parity alone trying to emulate Disk 1. Appreciate the help so far. tower-diagnostics-20251203-1155.zip

Magic smoke, a faulty rail. The data might be recoverable by a specialist, but no hardware I have can even recognize that a drive is connected. They have that fresh, fried component smell. With New Config, can I assert that the new zeroed drives both have valid parity, and then somehow error Drive 1 and cause a rebuild on it? Ideally if I pretend that the second drive never existed, or zero a new drive and posit it as Drive 2, it should only corrupt about 30mb of data on the drive I care about.

Hi all, not even sure how possible this is, but certainly hope that it will be! I have a 2 drive array with single parity, and today both of my array drives failed due to a PSU issue. I realize that under normal circumstances I would be screwed, but my second array drive has about 26mb of data on it and the rest is zeroed, so if I'm not mistaken, it should be possible to recover drive 1 in its near entirety. I definitely don't want to walk into this blind, though, so any recommendations or help would be appreciated.
