I have received Lacie 160 GB rugged drive. But the product is defective. I have used it with my Mac OS X 10.5.2. First few times it properly mounts on my Macbook desktop. I have copied about 5 GB of vidio file. After that it doesn't mount. I can't use it anymore. I am going to return it. Beach Camer's return policy is not good. They will not refund 100%. Even for defective product they keep 10%. They will return only 90% of the product cost even for defective product, it surprises me.Careful before buying it from Beach Camera.
