Brook, thanks for the pointers. It's my understanding that Lacie & G-Tech both format drives only for the Mac.
One problem has been happening. The new G-Tech drive mounts when the computer starts and then, at random unpredictable times, it drops off and I get a "improper device removal" notice. I guess that is the same as unplugging it or turning if off without unmounting it. To have it remount, I just turn it off and then back on again & it remounts without any problem. Maybe, my problem is related to iMovie since it frequently required "relaunching" when I am creating a new file. iMovie also opens more slowly when you go into it. There are no playback problems so long as I am in the two internal drives with any of the videos playing. Thanks again for your imput.
