Symptoms:
Delete takes longer and longer then stalls. On reboot no saved programmes but disc still shows as 72% full. Can't record. Disc related menu options all grayed out.
Actions:
Factory reset reinstates all menu options. Disc format indicates 'processing' for several hours then the HDR shuts down. Restart puts me back to 'no disc options'
Disc ordered as I had no suitable spares. The failed disc was dated 2014.
I'll update when new disc fitted.
