How can I erase DVD-RAM badly/incomplitetly formated with M$ Fat32??
Welcome to the forum
I suggest to use ImgBurn. Simply click on the little button shown in the pic and select FULL erase
It will require a long time (about 30 min for a 5x RAM disc, more for slower discs), so be patient
Install Panasonic's DVD-RAM drivers (just ask Iris at Toshiba.com) after having uninstalled InCD or similar software. Then format the disc as UDF and select "physical format". The process will take about 40 minutes, depending on drive and media.
I use IMGBURN with Full Erase and it works.
