Best practices
What to do first.
- Label every drive bay and disk position before touching anything.
- Take photos of error screens, disk order, RAID level, NAS model, and drive serial labels.
- Power down if the array is degrading, rebuilding incorrectly, or making unusual drive noises.
- Preserve the current state. The order of events matters.
- Ask for advice before replacing more drives, rebuilding again, or initializing storage pools.
Avoid
Actions that commonly make recovery worse.
- Do not rebuild a second time after a failed rebuild.
- Do not initialize, create a new array, factory reset, or change drive order.
- Do not run file-system repair on the only copy of a damaged array.
- Do not replace multiple drives at once unless a qualified plan exists.

When to stop
Stop before the next attempt if the data matters.
If you are unsure, the safest free step is to stop and ask what not to do next. Do not keep testing just to prove the problem.
- Do not send passwords, private files, wallet seeds, confidential records, or drive images through chat.
- Do not pay anyone or ship anything until the case, path, and expectations are confirmed directly.
- Keep the original device unchanged until you are sure the recovered files are complete and usable.
