Hello all, I hope I posted in the right place This week I bought my first md player sony mz-n505 second-hand and I encountered some problems. I can't transfer music from pc->md because I get the beautiful "nv err" and md make a click and shut-down. Recording from line-in is working, the player work very well and it reads all track, I tried all the solutions: reinstall sonicstage(win 7 64 bits), reinstal drivers, reintialize parameters from service mode....but nothing. When I try to transfer a file I get "Unable to transfer the track or tracks" When I try to reinitialize the disk I get "Initialization of the media failed" (error code: 0000662e) Any advice willl be helpfull. Thanks in advance!
