Panasonic DVR disk data rescue

Some video players are equiped with harddrives, which can record the TV
programme internally. Videos are stored in a specific filesystem, so neither you
can mount the extracted harddrive, nor you can play the files on PC. 

This is a how to extract the files from drive.

you need a python script dvr-recover.py by Stefan Haller
(tested for Panasonic DMR-EH55, DMR-EH56, DMR-EH57, DMR-EX77, DMR-EX85,
DMR-XW300, DVM-E80H ....)


to run it, you need python2

first, after connecting the drive to the computer, you have to find out
device name:


#on freebsd, on linux may vary
tail dmesg

da0 at umass-sim0 bus 0 scbus4 target 0 lun 0
da0:  Fixed Direct Access SPC-3 SCSI device
da0: Serial Number 94522D072504
da0: 40.000MB/s transfers
da0: 381554MB (781422768 512 byte sectors)
da0: quirks=0x2


so, the device name is /dev/da0

then, configure the dvr-recover script. it stores it's configuration to
sqlite database

#set the input device
python dvr-recover.py setup input add /dev/da0

# setup the target directory to 'wheretoexport'
python dvr-recover.py setup export_dir wheretoexport

# now, look up for chunks of videofiles in the device
# runs for several hours, or even a day
python dvr-recover.py create

# show, what chunks were found
python dvr-recover.py show


# sort the chunks
python dvr-recover.py sort

# export the videofiles to wheretoexport
python dvr-recover.py export

output is in .mpeg files. the script joins chunks to files. 
wait for several more hours or days

done!
