Hi all, When using my MZ-NH1 with an 80mb disc, everything works splendidly. When I use a Sony Hi-MD 1GB disc however, the unit seems to actually be recording but when I end the session, the unit endlessly reports 'SYS WRITE'. The disc is spinning and the text/light are flashing. I have tried multiple new 1GB discs and none work. I tried to plug the unit into my computer with the 1GB disc in and 'Initialize' (format it).. Same results. I bought this player on eBay and I don't believe this has worked from day 1. The unit is out of warranty. Do you all have any suggestions for me? Some friends have suggested simply purchasing a new unit as 1GB recording is essential for my use. Just thought I'd check here first. I have read that a Sony repair out of warranty can be upwards of $130 an hour and a product replacement is $222.67. Thank you for your time and answers, -Kevin
