i guess i understood the problem: the MD is a MD not Hi-MD. the recorder is a MZ-NH700 (Hi-MD compatible) i read in a thread: >>Note that you can't upload the recordings from your old minidiscs. Only recordings >>made in the new Hi-MD formats --PCM, Hi-SP and Hi-LP--can be uploaded. I checked the MD and i noticed that i used MD mode, not Hi-MD mode. Well i think i realized that i had to use Hi-MD mode.. so now i cannot move the tracks since i use the wrong format??? Why? What could be the difference in trafering files??? I hate it! i didnt know it and i used MD mode since i was using a MD (not a MD 1 GB!). i didnt know that i could use Hi-MD format on a simple MD..... i think this is very frustating since there are many rules that are not clear in the MD handbook! please correct me if i said something wrong. is analog recording the only way i have to upload my recordings?? thanks a lot, hope you can help me.
