Unless you have the ntfs tools:
sudo apt-get install ntfs-3g
Your system will not recognize the windows file system "ntfs". reformat
to ext3, which you need for linux OS any ways. (there are others, but
ext3 is what I use.)
sudo mkfs.ext3 /dev/sdb1
where sdb is the device of your usb harddrive and the 1 is the number of
the partition you want to format. *DOUBLE CHECK THIS* don't want you
reformatting your main drive. ;-)
Mine looks like:
froller at metis:backups$ ls /dev/sd*
/dev/sda /dev/sda1 /dev/sda2 /dev/sda3 /dev/sda4 /dev/sdb
/dev/sdb1 /dev/sdc /dev/sdc1
dev sdc is my usb drive:
froller at metis:backups$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sdc1 112G 191M 112G 1% /media/MERCURY_120
Once it's done formating, unplug and replug the drive in the usb port.
The system should automount and the USB Start Up Creator should
recognize it now.
