I have a 250 Meg Fantom Drive. The first one died in less than 5 month's but they replaced it with a newer model for free and even recovered all my Poser data from the old drive and put it on the new one.  To say the least, I learned not to leave an external drive turned on 24 hours a day 7 days a week! Now I just use it to back up my internal runtimes.
