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

Hi.  

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
Cylinders:1024
Heads:256
Sectors:63

Ok, I fibbed, 3 question actually.

Thanks in advance.

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
