I have two G-Tech HD that I normally connect to my MacBook, and they work fine. I connected both to my Time Capsule, but TC can read only one of them.

I have no idea what's wrong


Time Capsule, Mac OS X (10.7.5)

    So you have a USB hub.. and you are plugging both in at once?

     

    If you plug one directly into the TC does it work? Does the one that fails work?

     

    What format do they have? Are they identical? Check that both format and partition type are the same using disk utiity in the Mac.. the mac will be more flexible than the TC.. wrong partition type like MBR instead of GUID can have effect.

    Thank you for your help!

     

    Yes I have a USB hub, and I'm plugging each directly to the hub. Boths work fine connected to my laptop. I connected the one that fails directly to TC (with no hub) and I'm no able to access through TC; the other one connects with no problem.

     

    They both seem to have the same Apple format HFS+; but I notice that they are different models (?). The one that fails connecting is Mac OS Extended (Case-sensitive, Journaled HFS+), while the other is Mac OS Extended (Journaled HFS+). I have no idea if this makes a difference

    I appreciate any help!

    HFS+ case sensitive and HFS+ without is not a problem.

     

    But they are clearly very different boxes.

     

    Anyway.. the one that works as I said is GUID partitioned.

     

    Partition Map Type:          GPT (GUID Partition Table)

     

    The other unit that fails is the very old apple partition.

     

      Partition Map Type:          APM (Apple Partition Map)

     

    Repartition and reformat it so it is identical to the other.

     

    This may or may not fix it.. but there is basically nothing else you can do.. if the chipset is so changed that the TC cannot recognise it.. then that is too bad.. buy another USB.

     

    You of course will lose all data on the drive so backup before redoing the partition.

    That's make sense, now I can see the difference between the two disk. You solved my doubt.

    I'll move the content of the disk and try reformatting it, to see if works.

    I'll let you know.

    Thank you,

    Thank for pasting all the info.. it is amazing how it helps having data to work from.

    I formatted the disk, now it has GUID Partition Table, and voilà problem solved: both disk are available through TC.

    Thanks once again for your precise help.
