    Hi

    I have mounted a 160GB Disk in a Blade 100 with Solaris 9 and only see this:

    iostat -E:

    dad1 Soft Errors: 0 Hard Errors: 0 Transport Errors: 0
    Model: SAMSUNG SP1614N Revision: TM100-30 Serial No: S016J10XC08135
    Size: 137.44GB <137438952960 bytes>

    format:

    1. c0t2d0 <SAMSUNG SP1614N cyl 255 alt 2 hd 16 sec 255>
              /pci@1f,0/ide@d/dad@2,0

      2 backup wu 0 - 254 508.01MB (255/0/0) 1040400

    I found the following solution to make at least some of the disk visible:

    erased the disk label:
    dd if=/dev/zero of=/dev/rdsk/c0t2d0s2 bs=1b count=16

    and entered 65535 cylinders in format:

    At least 127.5 GB for a 160 GB disk :^(

    Is this currently the upper limit?
