Ok guys i solved the problem with the garbage characters. After CTRL+z there comes: F3 T> Then i used this command: m0,2,2,0,0,0,0,22 After that i was realy happy because of this: Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 00, Max Certify Rewr ite Retries = 0000 User Partition Format Successful - Elapsed Time 0 mins 00 secs F3 T> But if i connect the HDD now to the PC the PC will not boot. There is nothing just a black monitor. If i disconnect the HDD from the PC the PC is booting and i see the BIOS POST. What's wrong here?
