RAID 6 uses double parity, so it survives two drive failures – but not three, and not a bad rebuild. When a RAID 6 goes down, it usually means serious trouble: multiple failed drives, an interrupted rebuild, or controller issues. The upside: double parity gives our engineers more redundancy to work with, and recoverability is high.
Common RAID 6 failure scenarios
- Two drives fail, then a third during rebuild
- Rebuild interrupted by power loss or controller failure
- Large drive sets with latent errors during parity recalculation
- Accidental array re-creation or re-initialization
Yes – in the majority of cases. We image every drive, reconstruct the double-parity layout virtually, and recover the filesystem. Even arrays that were re-created can often be partially or fully recovered.
How we recover RAID 6 arrays
Our engineers identify each drive’s role and failure time, image all drives sector-by-sector, rebuild the array in software with the correct parity calculations, and extract your data with proprietary utilities.
Frequently Asked Questions
Sometimes – it depends on how much of the third drive’s data was overwritten. We evaluate it free of charge.
Typically 3-15 days depending on complexity; emergency service in 24-48 hours.
Pricing is per disk and case, typically $1,000-$2,500 per disk. Larger arrays mean more disks, but the quote is fixed before work begins.
