6tb disk: Very big device. Trying to use READ CAPACITY(16).

  • I just added a 6tb disk to my omv system, but in dmesg i see this warning:
    [ 640.881011] sd 9:0:0:0: [sdg] Very big device. Trying to use READ CAPACITY(16).


    what does this mean?

    For some/normal/small/old HDDs Linux use 10 bytes to keep track of stuff on the HDD. For very big HDDs Linux can shift over to using 16 bytes instead. That is "READ CAPACITY(16)".


    And everything works fine!
