Hope someone can give me some advice with the following problem. Whilst erasing a program from the hard drive of my Panasonic DMR-E100H DVD/HDD recorder, the system crashed and restarted itself. After the restart, any attempt to record on, delete or edit programs on the HDD resulted in the following error message - "This disk is for playback only, cannot record/erase/edit." Even trying to play back programs already recorded was giving problems (sticking, playing a different program to the one selected). The only option left was to format the HDD, which seemed to go ok, but then the system reset itself and is now stuck in a constant loop of startup, self check, shutdown, startup, self check, shutdown. The only way to stop this was to physically pull the mains out. Has anybody seen this problem before? Please help.
