Questions:For [...] transfer [...] error, users are advised to have some more clarification to identify if the problem is caused by hard drives or NAS hardware. Users can swap the error drive with another normal drive, and check if the log will report same slot error.For example, Users found that the 1st slot reports transfer error, then he/she can shutdown the NAS, switch slot 1 & 2, power on the NAS again, and check if the error moves to slot 2.
If the error moves to slot2, that means this drive might have some bad sector and users might want to replace it. If the error stays with slot1, users might have to contact with Asustor support for further investigation.
