Upon receipt it was dead, after a mixture of e-mailes and phone calls it was determined I needed to use 2 USB cables to power the drive. Since I only have 2 on my laptop, I cant print from the drive. after transfering 10 gig of pictures and 13 gig of mp3's the unit failed the next month. Again emails and phone calls determined my laptop did not have enough power to run the drive. The solution was an AC adapter.....great for a "portable USB drive" They said an AC adaptor would be sent...no adapter after 4 weeks now. I tried the drive on 4 other DESKTOPS, plenty of USB power, but no luck. I have lost so much information, pictures, and music and now no emails refering to my "service number" are being answered at all.A total lack of customer servive AND knolage of their own product. Think long and hard before dealing with Iogear!!
