At first, great thanks to Gradius and everybody provided help in this thread. Great news for everybody, I fixed the BSY error for my 7200.11 1T HDD, and I would like to share some experiences. At first, I followed all the steps but something wrong in the last step. I got nothing in the m0,2,2,0,0,0,0,22 command(I just waited for 3 minutes, I power off the HDD too early), and then disconnect the hyper terminal, and after that I connected everything again and ran the m0,2,2,0,0,0,0,22 again, after about ten minutes I got something below F3 T>m0,2,2,0,0,0,0,22 Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 00, Max Certify Rewrite Retries = 0000 And about another ten minutes later, I got something like these below User Partition Format 5% complete, Zone 00, Pass 00, LBA 00008DED, ErrCode 00000080, Elapsed Time 0 mins 05 secs User Partition Format Successful - Elapsed Time 0 mins 05 secs I power off HDD when I got this messages and then I plug the HDD to my PC and turn it on, everything is OK. So if you encounter problems in the process, don’t panic, your HDD and data are safe. Just find out the problem and then try again. There is nothing to worry about.
