Hi I am new here, I can not believe how many people with the same proble and no solution! I have noticed numder of questions related to the same problem - mostly MZ-N505's. Everyones are desperate to find the fix. Not many answers unfortunately. This must be something systemic? SONY must be aware of this (I am talking about recording not working, displaing BLANK message but playing old disks OK). This is not an software issue as it does he same with several different softwares. Please let me know if you find the cure for this problem. Thanking you BobA
