Hello, I have already send my disc and sent a letter with lots of details (I don't know if they need these details, but I think it is better to write too much than nothing !) : - material and disc used (for me, MZ NH 700 + HI MD 1GB) - version of Sonic Stage - explain what happened - number of tracks lost (+ time of these tracks) - list and descritpion of documents lost (live tracks, copies of CD, personnal documents as .JPEG, .DOC, .XLS...) - your name, adress, country, phone number Re-write your name and adress on the disc ! Hope they can do something for you !
