Can someone tells me if the fact that it's written "capacity: 42GiB (46GB)" means that I cannot insert a HD that is bigger than 42 ?

Because one of my HD is 72GB, and the "capacity" field is not listed.

Another question, it says "UNCLAIMED" but I have a "Vendor" field - so who is it then ? and is it normal that I have two different vendors for every socket ? ( FUJITSU / MAXTOR ) and also have different capacities ...

  *-disk:2 UNCLAIMED

       product: MAP3367NC
       vendor: FUJITSU

Would you please try to clarify your question? I'm really having a lot of trouble trying to figure out precisely what you're asking. –  HopelessN00b Oct 8 '12 at 1:48

It's actually fairly straight-forward.

  • UNCLAIMED: Means that there is no driver claiming this device. It is not a vendor field.
  • GiB vs GB: Two different ways of listing the total capacity of a drive.
    • GiB: The capacity where the unit is div-by-1024 (true GB)
    • GB: The capcity where the unit is div-by-1000 (drive-marketing)
  • Vendor: The PCI data for the device includes who manufactured the drive, this is that same field.

I'd be a little hesitant to call the SI, IEC, and IEEE definition of gigabyte "drive-marketing." –  jgoldschrafe Oct 6 '12 at 13:44
    
I understand the context of each field, but if the field is "UNCLAIMED" how is it that I have a vendor ? so the vendor is who ? the chassis ? if so, then how do I have two vendors there ? –  Ricky Oct 7 '12 at 13:57
