What branch and version of Sabayon, 4.x 5.x and x86 (32bit) or amd64 (64bit)?
I have been installing Sabayon 5.3 amd64 K on to a 80 gig 2.5" external drive (sata) and Sabayon 5.3 x86 G on to a 20 gig 2.5" external drive (ide) and they are working. Both systems have been installed via my 64 bit test machine
If I recall correctly when running the installer I was given the option to select the drive I wanted to install SL on
I was presented with a choice of 3 drives (internal, external 80gig usb and the usb 4gig stick)
I just selected the external 80gig usb and using most of the default options except for my country timezone and doing a create custom layout with the partitioning, the bootloader is installed to the one I selected (80gig usb)
If I leave the original internal hard drive in my test machine and install SL on to a external drive then any operating systems that are installed on the internal hard drive are added to the boot menu on the external drive, which is a pain as when I connect the external drive to another computer it has the entries in the boot menu from my test machine
As my test machine does not have the side panel on, I make sure that I disconnect all internal hard drives before I do an external drive install of Sabayon
I recommend that you disconnect your internal hard drive(s) plug in your external drive then switch on your computer and boot with your pendrive and then install SL to your external drive

Some mistakes are too much fun to only make once!
