This allowed you to essentially clone the intact video recordings over to a fresh HDD, without losing anything, and in a form that the recorder would still accept, read and work with as if it were still the original HDD.


THAT IS UNHEARD OF. All previous attempts at HDD cloning also cloned the corruption, a zero sum game.


So every other person on this thread is doing the insanely tedious "use an expensive obscure hex editor to reconstruct each little three second clip and painstakingly reassemble the videos onto their PC drives as coherent standardized files they can then salvage using PC authoring tools". That is a task for savants, or fools with a great deal of time on their hands: I wouldn't attempt such a thing if the videos I lost were priceless, never mind the typical mundane TV fare. What you did is something entirely different and the "holy grail" people here really want to discover: how to do a quick and dirty clone of a failed recorder HDD onto a fresh HDD, cloning the video data but not the corruption, and in such a way the recorder accepts the transplant without incident and without insisting on a reformat.


I'm not sure if some of the people responding to this thread after your post understand there are now two distinct recovery methods being discussed, it can cause confusion. It should be made clear that your "holy grail" method requires your "just tossed it off in an hour" special software hack that allows the cloning of the corrupted drive intact onto a new one. Unless you're willing to publish/sell this software, and an instruction manual, your miracle cure is academic: no one else here has any idea how to follow your footsteps. You are a genius, sir.

I've just spent 40 minutes composing a response to all the above (giving details of my success at recovering data from a Panasonic HDR) and then been told I'm not logged in and was not given any way of retrieving my text.


So, essence of this message is ....... never hit the Submit button before you cut and paste your text to Notepad, or whatever, or you'll have to start typing again.


Wait on for me to re-compose the original message and post it here. I may, however, post one or two more dummy messages because it seems I can't send an email to poor old andreasn91 (see his post above) until I've posted at least 5 messages.

See my posts above in June 2009. I accidentally (re)formatted the 250GB hard drive on my Panasonic DMR-EX85EB thinking I was formatting a DVD-RAM.


The HDD contained 100 hours of treasures that I had not yet watched so after reading worley45 (wade)'s posts in this thread I was inspired to mount a project.


I took the HDD out of the Panny and connected it to my PC (with an IDE to USB adapter cable) and followed Wade's suggestions for using HxD (Hex editor) and HJSplit (file joiner/splitter) to retrieve my treasures and then burn them to DVD. I created a few tools to streamline the process and ended up with 25 DVDs containing all my treasures.


In the meantime, so that I was able to continue using my Panasonic DMR-EX85EB, I bought a replacement Western Digital Caviar WD2500BB 250GB 7200rpm IDE/PATA for £30. Before fitting this into my Panny I copied onto it the first 320KB from the old HDD (Panasonic's proprietary formatting code) and bingo on switching the Panny back on I was welcomed with the information that I had 111 hours of Standard Play recordable capacity.


So my message is that almost anything is possible.


If you want more details of anything described above or if you want a copy of the code to format a replacement 250 KB HDD post here and I'll respond.

Hi Im2020


went round my folks yesterday for xmas dinner and their EX85EB is exhibiting all the symtoms of a HDD failure. Why do things always go wrong at xmas??
That said, there was nothing on worth recording - as usual!



They dug the receipt out and most annoyingly its 3 months outside its 2 yr warranty . It wasn't cheap...



So I've pulled the HD out and stuck it in my PC this morning and sure enough it's knackered - BIOS cant even 'see' it - just the 'thunk' of the arm hitting the end stop on power on.



Soooo....I'd be most appreciative of a copy of your code and partition image so I can stick a new HD in it for them. Would that be possible?


cheers

If you are not trying to get anything off the old hard drive, you won't need his code. Just get a new hard drive and put it in. Upon power up, the recorder will tell you that the hard drive is not formatted properly, and asks to format it. You say "yes" and it does so. End of story, it formats the drive and you can use it. Only one thing, the new drive you install must have a capacity equal to or greater than the original. It will format to the size of the original drive, even if you put in a larger one. A search here will turn up the drive models people have used in the past.

Hi


oh ok, thanks for that.


I thought I'd read elsewhere (before finding this site) that you needed an installation CD that was only available to authorised dealers in order to format a new drive due to the fact that it contains a separate partition with firmware on it.


Confused.. :-/

Your link doesn't work
and since your EX Panny is a European model it is possible it requires extra steps. The US Pannys only requires a compatible drive be installed and the firmware will format the drive correctly.

Pioneers in the US/Canada require a special service remote to replace the hdd but not the Pannys.

His link worked for me.


I was very surprised, to say the least, when I read that thread he was pointing us to. It seems that such an HDD replacment procedure is not as simple as with E85, EH50, Eh55, EH75 models *I* am familiar with. It's odd that Panasonic would change their design and put the firmware on the HDD in these machines. It changes the process for replacing the hard drive from trivial, to nearly impossible. Why?


mbslk280, I am very sorry for misleading you in this. I saw your model, EX85EB, and never really mentally processed the "X" in the EX, so I was speaking of a different model completely. All my mind processed was the "85" and that was my mistake. They shouldn't re-use model numbers, it confuses people like me.



I bought some IPOD accessories as a Christmas gift this year, making the HUGE mistake of getting IPOD NANO Gen 4 items, instead of IPOD NANO Gen 5 items. They are incompatible apparently. Well, *I* didn't know!

lol - no worries. Thanks for clarifying.



Yep, its most frustrating. They bought this model specifically 'cos it has a built in SD card reader and so can copy their photos to DVD (they dont have a PC).


The HDD itself (which I believe has a 3yr warranty) is dated 02 SEP 2006
Ho hum...


Happy holidays

Hi, I've stumbled across this site after trying to fix my sisters EX85EB. HDD was dead (clunking) so have fitted a replacement and it's asking for the service CD.


Would really appreciate the code to format so it works, and also confirming what file system I should format in?


Thanks, Mark

Hi Mark


I PM'ed im2020 around Christmas time inquiring about obtaining a copy of the code to format the HD but never received a reply.


If you fair better, or manage to get hold of the holy grail installation CD, please do let me know!


cheers

Well Done Worley45!! Yesterday I pressed the wrong buttons and instead of deleting a DVDRAM, I deleted (not formatted) my nearly full hard drive on my DMR-HS2 !!! I found your post, and am starting the long process of trying to recover some precious recordings. I have succesfully replaced the hdd in the -hs2, so can continue using it. I have put the hdd directly in the pc, and it can see it as "hard disk 3", there are already 2 hdds in there, but cant play the saved "a1.mpg" file with any DVD player prog. It also is a lot bigger than 16Mb. Are there any more tips that might help?

I recently tried installing a 500G HDD to my Pana DMR-XW300 to replace an ageing 250G. Earlier posts suggested any larger HDD would be formatted to 250G. No luck for me, my system simply reported "Format Unsuccessful".


I then cloned the 250G onto the 500G using a program called Selfimage. I installed the 500G and it worked just fine. All recorded titles were available and remaining disk space was as per original 250G HDD. So far so good.


While the 500G was installed I deleted one recorded title. I then removed the 500G and reinstalled the 250G. The DMR wanted to do an automatic format as it could no longer access the titles. It seems the DMR records the title information (index) somewhere other than on the HDD. If the HDD does not match the recorded title information, the DMR tries to reformat the HDD, ie all titles are lost. This could explain many of the earlier automatic reformat comments in this post. Once you install a different HDD and do any reformat, even the original HDD will no longer work as there is a mismatch between the title records and the HDD.


I reinstalled the 500G HDD and because the HDD contents match the title records, this continues to work fine. I am now stuck with using this HDD as it is the only one that matches the title records.


Hope this info helps someone.

You could try cloning the 500 back onto a new 250 if the software allows it. You only need the first 250 gig copied.

Hi there!


My uncle had a problem with his Panasonic DMR-EH56: The DVD-drive broke down and the whole recorder seems to be useless. But I wrote a script to copy most of the data from the hard drive disk. The data will be saved as MPEG files. So almost every application should be able to read them.


For this special Panasonic recorder the script worked really good. From the 160 GB (~ 149 GiB) hdd I could automatically recover about 70 GiB (this means, that the script found parts of the same recording itself and the film was complete without manual work). But I cut the files, so the size is without any advertisements.


The script also found the other data (so probably around 70 GiB), but it wasn't able to recognize which of the pieces belong together. But I think, that many of this recordings were deleted, because most of them are very short. The script has also problems, if advertisements are cut out, because after this process the timecode is not continuous anymore. I don't really know the content of the hard drive disk, because it wasn't actually my recorder.


Now the problem: The script should work, but I can't test it more than I already did. Also some parts of the code are far from perfect (and the very last thing is not completed yet), but my time is limited.


Is anyone here who has interest? It's a Python script (tested with Python 2.6 ). I used it on a Linux based system with a copy of the hard drive disk (copied with dd). So I needed the space for the copy of the hdd and for the MPEG-output of my script (~ 2× size of hdd). But it should be possible to use the hdd directly as input (haven't tested this, but it definitly requires root-priveleges.). I don't know if it's possible to use the script on Windows, too. If Windows can create a exact copy of the disk there is no problem. On Linux you can use the hard disk directly as input file (/dev/sdX), don't know if this is also possible on Windows (I'm not a Windows user anymore).


It took me a while to write this script, so I would be happy if my solution could help others too. But be aware: Maybe it's a bit complicated (especially for Windows users), but not as complicated as looking for the MPEG-chunks by hand



If there are no interested people, further work would be unnecessary in my opinion. Then I would use my time for other things
But would also be a pity if the (currently not fully completed) script would lie around on my hard drive.


Cheers

I'm definitely interested. Three potential problems:

1) I'm running WinXP (but I know how to run a knoppix disk)

2) My data is now stored as an image file

3) The data came from a HDD that required a format. Panny HDD formats are 'simple' in that they only overwrite the TOC (or whatever the correct linux term is) - the actual mpeg data is still there, just no direct pointers to what is what.


Let me know if you think it'd still be OK to use and what I'd need.
