It is a used item, and there are inevitably signs of use, so please consider purchasing with this in mind. For those considering purchasing due to a price reduction request: We have thoroughly checked the operation (or rather, it was working normally until just before), initialized it on the Web settings screen (0 write), and returned it to the factory settings at the time of shipment. The RAID function is inevitably disabled. Therefore, the RAID function may appear as "damaged" on the Web settings screen. In reality, it is not damaged but disabled, so please format it again.
