I bought a portable hard drive of Trekstor me some time ago. Was also very convenient with pocket etc. But apparently the company TREKSTOR should generally stay away away. Whether Trekstor itself manufactures or manufactured cheaply. It's just dirt, which is good for nothing !!!!!! Once the drive was a few weeks in operation, failed the first power supply. A "deeply" disappointing & especially annoying conversation with Trekstor and I got with Oh & Barney sent a new one. Unfortunately, the replaced PSU was good for not very much, so I after a few weeks had a conversation with the company TREKSTOR TrekStor and refused to exchange the power supply. Spare came into existence through Amazon or through a new acquisition of the power supply. Unfortunately, I had them also turn a few weeks joy. With the "ridiculous" power supplies, I can open a business.
Conclusion. TREKSTOR should rather stay away from things, where they have no idea of and make better close up shop than to bring scrap to the people. Faith each of the hard drives will buy from this manufacturer, himself no great favor is doing with it. Better to such brands as IOMEGA etc. The obviously know where the wind blows long. Whether the good piece at all 1-star is worth, I dare even to doubt.
