Using USB Drives

[wm2f]

Hi All,
I have read alot about not being able to use USB drives since there not bootable.
I have a PowerBook G4 with a 30 gig drive. Just to small. So I bought a 160 gig drive.
My method to clone the drive:
Use SuperDuper to do a full copy to the USB drive. Yes its slow, 25 gigs took about 5 hours.
Install the new hard drive.
Partition the new drive, I just split it. Mac OS Extended Journeled on both partitions.
Clean install of Tiger on one of the partitions.
The machine booted to the new install.
Loaded SuperDuper on the new install.
Set SD to copy to the other partition.
No problems copying to the new drive. Again 5 hours going back.
Opened System Prefs and set the Start Up drive to the SD cloned copy.
Machine booted fine and it was just as before.

Real nice Utility. Will be purchasing the SD since its a life saver.
