DOA 
I read a lot of good reviews for this hard drive, so I decided to give it a try. Maybe it’s because I have a Mac, I don’t know, but my drive didn’t work for me at all. I looked under system profiler to see if my MacBook Pro recognized it at all; it showed up as a firewire device but that was it. I even tried to see if my Windows XP virtual machine would recognize it; it didn’t. I got an error message. I’d also like to mention I tried both the firewire and USB cables that came with the drive; neither worked. I ended up getting an RMA from Amazon the day after I received it.
Superb! 
I bought this product for $99 in order to back up my G4 PowerBook. I formatted it so that 160GB became 149MB but I could successfully copy all my stuff onto this external HD. (Just for your information, I used “Carbon Copy Cloner”, which is downloadable for free. It did an excellent job.) It took me some 1.5 hours to backup/copy 31GB. I don’t know if this is fast or slow, but I am satisfied with the fact that I can now use this external HD as a start-up disk (with firewire). For review of other features, I will refer the reader to the rest of this review section. Incidentally, the sales price changed right after I purchased this item. Remember that I bought it for $99 plus Shipping $6.35. The seller was J&R.
Great small portable hard drive, firewire
Works great with MacBook Pro. A very useful tool. Very happy with it. Connect with fireWire and USB.
Great Product
Just as described, it’s a great product. Very small and very portable, with the amazing feature of Firewire Bus power. I plan to order several more of these and just use them as I need. I am quite pleased with the product and I highly recommend it to everyone.
Great purchase, great price!
The product has been 100% satisfactory; it came speedily and worked like a charm. Nice and small, didn’t overheat, easily powered via USB. Setup was really simple. Has worked well with my MacBook and Leopard so far.
I recommend contacting the seller w/Qs re this product; it certainly helped me out. I don’t have much to say, but I highly recommend it.
