I’ve bought a second hand DMR-E60 to use the 60 (!) DVD Ram cartridges i’ve got from a friend. The cartdriges were used on an older DVD/VHS recorder, probably a DMR-EV57 (?) This broke down and repair was too expensive.
(Cartridge type 4. Double sided 4,7 Gb Panasonic.)
Every disc i’ve tried to format i get the error message “non-recordable disc” and in disc management the option ‘disc protection’ can’t be changed because the “content of the disc is protected”.
Opening the cartridge and insert the disc without cartridge has no result. Same message appears.
Anyone an idea how to change the disc protection to “off” so i can format an re-use this large amount of Ram Cartridges?
