For $90 per hard drive, we will repair or replace a faulty PCB, firmware, and/or USB interface. We will also remove any malware and viruses present. This service does not include fixes for mechanical issues or other cases where full data recovery is needed, such as logical failures. If any of these errors are present, we will offer to fix them if possible, but the cost will be higher. This service does not include a rebuild of your array. NOTE: Drives within your array which do not require repairs will not add to your cost.
