But now when the USB drive is not plugged in, I get grub error 17.

Is it possible tha Grub has "issues"? Or am I calling it a "bug" too
soon
and is it just a problem between keyboard and chair? ;-)



It sounds like grub was installed to the usb drive. Please boot with a
livecd and post /boot/grub/menu.lst. Also, post the result of fdisk -l
(run
as root or su).

If grub was installed to the USB drive, he would not get the grub error
without the usb drive plugged in.

Which is exactly what he DOES get Joe.....

Guys, please...
Opensuse is a great Linux distribution, but it still cannot install grub
on a disconnected, unpowered usb disk that is more than 10 meters away in
another room. If it could, Respect!!
I can assure you with 200% certainty that the usb disk was never, and I
repeat, never connected when grub was installed.

To prove this, I look in the first 1K of the device to see if grub is
installed. First I show you sda (first fixed hard disk) and sda2, the
/boot partition, then I show you sdd (usb disk).

As you can see, grub isn't installed on the usb disk.
