In RAID 0, data is fragmented between disks for speed. If one fails, theoretically everything is lost. In professional practice, it is sometimes possible to partially clone the damaged disk and reconstruct the logical volume, recovering small files or data fragments, although large files may be incomplete.

RAID 0 offers maximum performance but zero fault tolerance: a single defective disk breaks the striping chain. However, it is not always a total loss. In the lab, the failed disk is cloned as much as possible, ignoring bad sectors, and combined with the healthy disk. Using specialized tools like R-Studio or UFS Explorer, the striping map is manually reconstructed, and files whose fragments are intact are extracted. Small files or those with minimal fragmentation have high chances of complete recovery; large ones often lose parts. The key is not to rebuild the RAID on the original controller, as it could worsen the damage.
