Hello :) I just bought a NAS542. The data stored on this NAS is rarely accessed so I need to periodically check the integrity of the data, but I can't find any such setting. Is there a scrubbing function on the NAS542?

    It can be emulated, more or less. By executing

    dd if=/dev/sda of=/dev/null bs=16M

    the whole surface of the first harddisk will be read, and so the disk firmware will be triggered to refresh difficult to read sectors. Do NOT exchange if (inputfile) and of (outputfile) as it will wipe your disk.
