[OpenIndiana-discuss] Seagate 3000GB Drive only shows 746GB

[Reginald Beardsley]

There are at least 3 issues here:

1) USB drives can't use format(1m).  The man page for rmformat(1m) suggests it will create an EFI label for disks over 1 TB, but it doesn't appear to work.  See below.

2) The USB mass storage driver may not handle disks over 1 TB.  I know that was the case w/ Sol 10 u7 when I tried to use a 1.5 TB USB disk. In that case, Solaris simply refused to see the device at all even though Linux and Windows did.  

3) As noted, the USB/SATA interface in the enclosure may not handle disks over 1 TB.  A more recent enclosure should solve that problem.
If the disk came in the enclosure, then it should work and it's probably a driver issue.

As an experiment I hooked up the Hitachi drive I'm about to RMA because of SMART warnings about sector reallocation via a USB<->SATA adaptor.

fdisk has this to say:

             Total disk size is 48725 cylinders
             Cylinder size is 32130 (512 byte) blocks

                                               Cylinders
      Partition   Status    Type          Start   End   Length    %
      =========   ======    ============  =====   ===   ======   ===
          1       Active    Solaris2          1  48724    48724    100

I tried to tell fdisk the sensible values, but fdisk wasn't buying it.

In this case I don't know if the USB<->SATA interface can handle large disks, but I do know that Sol 10 u8 can create a 2.79 TB pool on the drive using the information in the disk config file if it's connected to the SATA controller in an HP Z400.


I can't say where the problem lies, but because the disk works via a SATA connection but not via USB, I think it's somewhere in the USB<->SATA chain.  Unfortunately that has lots of moving parts :-(
