My iMac, 1.8 GHz, OS 10.5.8, PPC's internal hard drive is failing.  Rather than replace the internal drive, I had hoped to use an external USB drive to run the OS.


When using the OS 10.5.x install, I am repeatedly told the OS cannot be installed onto my external drive.


I cannot narrow down the isse.


Is it because it is a USB drive?


Is it the format of the drive?  It is currently formatted as "Mac OS X Extended Journaled."


Is it indicative of some other problem with the computer?

iMac, Mac OS X (10.5.8)
