RAID 5 recovery with 2 failed disks — possible?

RAID 5 stripes data and parity. With one failed disk it can rebuild; with two simultaneous failures, there’s usually not enough information left—self-repair isn’t possible.

Key points:

• RAID 5 tolerates one disk failure; with two failures, data is typically lost.
• Recovery may still be feasible in some cases depending on remaining blocks/parity.
• DIY attempts risk overwriting parity/stripes—seek professional help.

Approaches:

1. Identify failure timeline: If one disk failed long ago and the second failed recently, partial recovery chances may be higher.
2. Specialized software: Some tools can infer missing parity, success depends on continuity of remaining blocks.
3. Lab reconstruction: Experts analyze parity/stripe geometry with dedicated hardware and custom algorithms.

Recommendation:

Do not reinitialize, reshuffle, or “rebuild” blindly. Contact a professional recovery lab immediately.
