How do I perform a ufs format on a 160 Gb USB external hard drive with Solaris 9?

Posted on 2006-04-26

I have two questions which I've been trying to figure out for days now:

1.  I just purchased 2 Iomega 160Gb external hard drives which I intend using as mass storage devices on a Solaris 9 system.  

Doing a prtconfig -D command, I can see the USB device listed.  I used the mkfs command to create the ufs file system, but managed to get only 72Gb on this drive.  How do I format the full capacity of this disk for ufs?

2.  How can I determine on this Solaris system whether the USB port is v1.1 or v2.0, and how can I optimize the setup on the USB port for maximum transfer speed?

The hard drive info:

Barracuda 7200.9

Capacity:160.0 GB
Speed:7200 rpm
Average Seek Time:11 ms

Ok, I fibbed, 3 question actually.

Thanks in advance.

    Do you have x86 or SPARC Solaris?

    IF you are on x86
    1.  Install patch 119443-02
    2.  Look to your messages file or dmesg command, you will see either USB 2.0 device or USB 1.10 device when device is plugged. It's a real speed  of your device.
    3. If your internal usb hub is 2.0 and device is 2.0 driver detects it automatically. Otherwise - no way (or install usb 2.0 external pci card)

    IF you are on Sparc: I guess not.

    Thanks for your reply.

    1.  This machine does not have patch 119443-02 and unfortunately, being one of our lab machines, I'm not at liberty to install any patches.  What does this patch do for formatting a USB hard drive?  I'm still not sure how to format/partition/mkfs this particular drive.

    2.  I used the dmesg command to determine that it is indeed a USB 2.0 port.

    1. Patch 119443-01 enables support of large hard drives in sd driver for drives >73G in x86 platform. USB storage is handled by sd driver (it looks like scsi drive even it's an ide in usb enclosure).
    2. dmesg | grep -i usb
