QNAP TS-451-4G Data Recovery Caselog

30Apr25: This is a qnap 4 drive nas system in for data recovery. Model number TS-451, all data has been lost because it stopped detecting. When you turn it on it shows normal green leds but this is a red herring because the customer has tried to repair this themselves by replacing drives and attempting to rebuild the file structure raid data recovery is the hardest to solve when inexperienced people start mucking about with the drives and settings. Now one drive is totally useless for data recovery and a 2nd drive has added an extra 501MB partition causing more damage. We found the original raid settings and successfully recovered all the lost data.The original offset was used with 3/4 drives ignoring the extra partition.
