Unfortunately, this external hard drive has persevered only 5 months of occasional use. They could now send in warranty but because the data on the plate I did not want to do this. After opening the case a Samsung ST2000LM003 emerges. With the help of an adapter, the drive is running properly on the computer. So is the SATA Converter - USB3 defective - pity. Now I'm going to find a new empty case and in future this brand rather avoid. Unfortunately, I have of the Seagate Backup Plus Slim three piece, as is a very bad feeling for the other two, especially since these panels are used as a backup medium.
