@ der Snoezie Thanks for your Answer! But I think too thats I have another Problem. After the first Panic ;-), i´ve taken my Harddisk back into my PC and I think my Sata Pover Supplie was not OK before, because now it will be found in the bios again. But I can´t boot Windows, I think it´s a damage on the start Routine of Windows and i will try to repair it in the next days. So you can delete my Disk out of the list. Thanks for your supplie and i hope only the best for all with damaged Seagate Harddisk. Greetings
