First decide on the problem occurred only every few days, and then increased to several times per day. Then I decided myself to Fujitsu-Siemens to turn, for Warranty. The hard drive I had to send to a service center at its expense. After 1 1/2 - 2 weeks I had the hard drive. For 3 days you worked, where she was but little used, and then the error occurred again.
I've then turned to Fujitsu, where I was told that I should send in the plate again at my expense. The case is the same error as before 1. Repair or that the error occurs for many customers, it simply ignores at Fujitsu.
So very poor service for a lousy product. I can only advise any of the purchase.
By the way: Installed is a Seagate hard drive.
