Finally I managed to do the procedure but the end was not as described. After the first time the disk was still not recognised, spinning, but not read. I wet through the al process again including the optional part ((i4,1,22 command) but with the same outcome. At the end I do have a message Max Wr Retries ...etc. ending with 00C8, but the following message from teh manual has never appeared: User Partition Format complete, Zone 00 ..... etc. and I got next message User Partition Format Sucsessful - Elapsed Time 0 min 00 sec. (But some of the others were referring having the same message and it worked for them.) It is strange, 00s. Is not it? Something is missing. When I connect it through the USB I can see the drive as mass store device in device manager, but not in My Computer. In the Computer Management the drive is seen as Dynamic, but saying "Foreign" with yellow triangle. When connected normally, it is not seen in BIOS. Also some Seagate diagnostic test passed, some not (short drive self test failed, generic tests passed) Is there any chance for other steps? thank you for your opinion
