What’s on the disk
To remove the hard disk you don’t have to remove the entire top cover. There’s a small door at the bottom behind which the drive is located. It also has a warranty seal. When connected to a PC (I’m using FreeBSD), fdisk shows that there’s no valid partition table on the disk. Let’s see if there’s some text:
# cat /dev/ad3|strings|less
Amongst the output we see

TFS2
Is TFS2 the name of the file system? I did some googling, but no luck.
Further on the disk, the names of the recorded videos appear.
