I have Two models of Hi-MD Minidisk Players (MZ-NH600D and MZ-NH800D), in spite that Sonic Stage is usually cumbersome to use; I transferred most of my cd's to 5 Different Hi-MD minidisks. Everyone knows how long it takes : to record the CD onto your computer; get the titles for the whole CD and every song; Transfer the songs from Windows Media player to Sonic Stage; Finally to Convert and Transfer all songs from Sonic Stage into your Hi-MD minidisk. Repeat all this process, 50, 100, 150 Times. It's just too much work to do over and over. When I bought my minidisk players, I remember One of the reasons for me to do it, it was the advantage that having your music stored in a disk, it meant that in case that the Player breaks down, your music is SAFE. Well, I just discovered that after 2 Years of using my favorite recorded Hi-MD minidisk, the music file just disappeared !! When I tried to use it the last time, the player just displayed a message "No track" !! How is it possible that this happened ?? I was thinking about buying a New generation Hi-MD player or HD Sony player, but with this current situation, I am Not sure about it anymore. Am I the only One with this problem ?? How did this possibly happened ?? Thanks for your Attention and Help. Greetings from Chicago.
