[clue-tech] mount second hard drive

[Bob Meetin]

1) David got his beer and then some...
2) I got a new computer and now a new computer with an Ubuntu desktop 
and some other sweet goodies.
3) So now back to the drawing board, here is the output of script 
(hadn't used it in many years):

root at syncsync: /binroot at syncsync:/bin# fdisk -l /dev/hdb
root at syncsync: /binroot at syncsync:/bin# fdisk -i /dev/hdb
fdisk: invalid option -- i

Usage: fdisk [-b SSZ] [-u] DISK     Change partition table
       fdisk -l [-b SSZ] [-u] DISK  List partition table(s)
       fdisk -s PARTITION           Give partition size(s) in blocks
       fdisk -v                     Give fdisk version
Here DISK is something like /dev/hdb or /dev/sda
and PARTITION is something like /dev/hda7
-u: give Start and End in sector (instead of cylinder) units
-b 2048: (for certain MO disks) use 2048-byte sectors
