mbraden-u60#

The device I am looking for is the Maxtor OneTouch.

Note: Remember in Solaris, the syntax for a device is c=Controller, t=Target ID, d=Disk ID and s=Slice or Partition where slice 2 is used to represent all the partitions.

To list the partitions on the Maxtor OneTouch USB drive, use prtvtoc with the Logical Node from from the rmformat output.

Use prtvtoc to show the partition map of the device.

mbraden-u60# prtvtoc /dev/rdsk/c0t0d0s2
* /dev/rdsk/c0t0d0s2 partition map

* Dimensions:
*     512 bytes/sector

*   24620 accessible cylinders

* Flags:
*   1: unmountable
*  10: read-only

mbraden-u60#

To mount and use the USB drive, mount partition 0 to get the root partition of the USB disk. In this case, the root partition is slice 0. So mount /dev/dsk/c2t0d0s0.
