I have no idea how i could find out if the HDD is meihdfs or udf. Its also not described in the readme.

Hallo,
leider habe ich meine Festplatte neu Formatiert (Panasonic dmr-ubc90) , somit sind alle Aufzeichnungen weg!

Kann ich mit dem Programm die Aufzeichnungen wiederherstellen?

Gruß

How to reproduce:
Install kubuntu 15.05.64bit, run sudo apt-get install build-essential , run "make" in meihdfs/extract.

I get error:
cc -O3 -mtune=i686 -march=i486 -pipe extract_meihdfs.c -o extract_meihdfs
extract_meihdfs.c:1:0: error: CPU you selected does not support x86-64 instruction set
/*
^
extract_meihdfs.c:1:0: error: CPU you selected does not support x86-64 instruction set
: recipe for target 'extract_meihdfs' failed
make: *** [extract_meihdfs] Error 1

Its a 2013 AMD 64bit cpu. everything is working fine on this computer. I dont know why i get this error.

Hi,
I wasn't able to compile it under linux due errors about cpu. After I deleted the 2 parameters from makefile it throws other errors.
Sorry cant paste it here now due I'm not under linux right now.

I wasn't sure what FS is using the Panasonic E85H, I found nothing useful with Hex editor on image.
Under windows hardly but able to download the windows binaries. (download didn't start)
I gave a try to UDF_DUMP and it successfully extracted the files from the image, but DVD-VR doesn't work to extract mpeg. If I'm right this would be its goal.
I added to paramaters the .IFO and same .VRO filenames but it gave me errors for more filenames:

• invalid DVD-VR IFO identifier
• Failed to MMAP ifo file (Exec format error)

All of .VRO files are playable with MPC-HC

Thanks the tool anyway!

Hi,

UDF was originally intended for optical media, but could also be used on HDD, which Panasonic then has done. Would it be possible to use the UDF version of panasonic-rec on optical disks written by, for instance, a DMR-EH52 that were not finalized?

I have lots of written, but unfinalized DVD-R. The DMR-EH52 is still functional, so I could finalize those disks. But I stopped finalizing before I migrated to a digital DVB recorder for a reason:

The clutch that hooks the disks onto the spindle motor after loading went unreliable. The DMR-EH52 applies WAY to much torque to the disks, and with the increasing collection of dirt or grease on the (supposedly) rubber surface of the clutch, and after all those years possibly a hardening of this rubber, disks started to skip upon the violent acceleration and breaking action the motor applies, leaving a number of them ill-burnt and unsalvageable when finalizing them.

So I would seek a way to read out unfinalized disks on the Linux PC...

So far I had no luck, my LG (Bluray) optical drive does not even hand over blocks when I access /dev/sr0 with dd, getting I/O errors on disks that the DMR-EH52 plays fine...

I can look into the sessions on the disks with DVD+RW-tools, so the session containing the video data could be identified, but that about all I can read from them...

Thanks

Hello,
It is Possible to add support for dvr-560h?

If the harddisk of the Panasonic recorder someday fails and I want to replace it with a new 250GB 3,5" IDE HDD, I would have to write the MEIHDFSv2 filesystem structure to the new HDD, right?

Is there a way to create a very small image of the empty MEIHDFSv2 HDD, instead of storing huge full 250GB image? And is it possible to write that small image to the new HDD?

(Does it have to be a 250GB HDD? Or would 1 TB HDD also work?)

If anyone's interested in building this tool on macOS then download source, install xcode commandline tools, and edit Makefile in which you replace -mtune=i686 -march=i486 arguments with -Doff64_t=off_t -Dlseek64=lseek

Original arguments were meant for 32bit building I guess and new ones are just redefiners of off64_t and lseek64 to off_t and lseek because they work the same way on 64bit.

Udf doesn't compile since latest modfications ("... support for raw direct access to hdd ...", commit e31db7b). See output:
