Rebuild goes wrong

Everything looked nominal. This case is actually kind of unexpected example of routine operation going belly up, the NAS owner ends up looking for recovery options after RAID 5 crash

Recently our quite old NAS Iomega Storcenter 200rl with a RAID 5 out of 4x500GB, reported a harddisk failure and our administration replaced one of the disks that was marked. Then the Storecenter told that it was synchronizing the data. After synchronization the NAS told that 100% of storage capacity is free and so it tell until now… I am interessted in options to revocer the data.

Certainly does not look like something was done wrong; if the NAS have sensed the rebuild cannot be completed, it would have had refused to even start the process. Certainly, with a wrong disk replaced, the rebuild does not happen. In this case, however, the rebuild was completed with no reported anomaly – something else went wrong.

With something unknown going wrong, it is difficult to predict if the case is recoverable. One can give our Home NAS Recovery a spin, but there is no guarantee of success. Cases when rebuild goes wrong for no apparent reason are always dicey.
