FZ50 files unreadable problem...

Go to last post
The problem may have already been explained by previous posts, but do you have anywhere you could upload a RAW file and it's matching jpeg? (free fileXoom account?)

If so, I'll look at it in a hex. editor and see if it's obviously screwed.

Drew-

Basically that is the answer I got from panasonic...and that is a lame answer or lame way for the camera to operate. I have used more than 25 different cameras over time and none of them had any issues taking the card from the camera and copying them to a laptop and then reinserting the card and filling it and finally transferring all the files to the desktop.

I don't think I can keep using this camera.

I had the same problem detailed here and my solution.

I suspect that if a user takes the card out of the camera, and uses
a card reader with Windows Cut and Paste, then reuses the card
without formating it again in the camera, it may become unstable.
I tried everything to recover the files that I could think of (I
was in a hotel room) without any luck. I used other cards until I
got home and then put the locked "bad" card in the camera,
connected the USB cable and I was able to get my pictures.
Unlocked the card, reformatted the card in the camera, and
everyhting appears to be ok now.

I doubt you may be able to recover those pictures, but good luck.
I'm now carrying my USB cable as a backup in my gadget bag.

That would be great. I just opened a filexoom account. my user name is tomoc and all that is in the folder is the two lumix files...have no idea what is on them...could have been pointing at the ground .

cheers,

Can't login without username AND password which you shouldn't give out :) , so can you post file links (put a semi-colon on the end of the .jpg to stop it being displayed). Go into "My Files" in your fileXoom account, right-click on each file in turn and "copy shortcut" (assuming windows) and paste to reply (sorry if I'm stating the obvious!).

A quick look at the files will reveal if they're just random data (FAT directory/chaining errors) or if they look anything like a real file.

Thanks. Graphic converter: "File Format not recognized" on both .jpg and raw files.

Sorry, but both the jpeg and the raw consist of mainly binary zeroes, with what looks like an occasional 'deleted cluster' marker.

There is no data to recover :(

Looks as if the card has had all files deleted by some means but the folder entries left intact?

Since I bought and use a card reader I have never had a corrupted file in any transfer .... and that is about 60,000 photos from 3 different cameras.
I do no editting in the camera
I do not transfer photos with the camera
I delete the photos from the card in the reader after every transfer.
I format the card occasionally... every 10 or 12 transfers

And for about 50,000 of those transfers I use a program called "downloader pro" to download and a basic organize and the delete. (each camera to its own folder and by date)

I've never had a problem with that, either, Dave.

In this case, I COPIED from the card and put the card back in the camera so that I would just have one step to load everything on my desktop when I got home.

I have never had a problem with this with any other camera.

deleted files from card right from my builtin card reader in the

problem. Now using FZ30 with Transend 1gig cards.

Colin-

these files were copied to one hdd and then a few more pix taken then moved to another hdd... the ones that were copied to the first, were still readable on the second hdd but all the pix taken after reinserting the card are the unreadable one... they all seem to be the same exact size (generally) and are timestamped at what i would expect them to be.

no hope?

thanks,

tom

Gene-

I have about the same amount of images and the same experience until these two.

I usually do exactly what you do (I use a 32bit pc card adapter to do the transfer and it does 2gb in about 4 minutes).

In this case, I first COPIED the files to the laptop, then reinserted it to fill the card and then MOVED them to the desktop when I got home. the first images are fine, the ones taken after the COPY are not readable.

I can see that there is no way that i can copy and reinsert with this camera.

thanks,

tom

Hi eveyone-

Thanks for your ideas everyone... I'm giving up on the files I can't read... Colin can't see anything in them with a hex reader...

The help I got from Panasonic was just terrible and quite frankly, the only support I have had was here in this forum.

I sent two emails via the tool on their website and neither got me a response (possibly because I entered more than the allowed 600 characters, but there was never an error or rejection message on the website). Then i phoned tech support, got the 20 questions routine from someone who knew less about the camera than I did. She checked with a supervisor and advised me not to reinsert the card in the camera and to format after every transfer (the manual says "seldom")... that they had no idea why or how it happened but stop reinserting the card with files on it... great and thank you very much...

Now for the request (if anyone is still reading my rant)... would someone please test this issue on your FZ50... take 5 shots, copy them to your hdd and then reinsert the card and take 5 more and see what happens...

thanks so much...

tom

COPYING files should do no harm whatsoever. MOVING might but shouldn't.

I usually use Downloader Pro which basically copies files to HD, then put the card back in the camera and shoot some more. I keep going till a card is nearly full before swapping to another card that I've formatted in the camera. I've NEVER had a problem doing this.

Can I suggest that you reformat the card in the camera, and only ever do a COPY to the pc/mac.

The only thing I can think of that MIGHT cause your problem is if you format the card on a PC and then use it in the camera. Not all FAT implementations are the same.

I have a SanDisk Ultra II 2gb card. I have on several occasions copied files (jpg.) from the card to my PC via the card reader built into my PC with no problems all the while not removing them from the SD card.

One more thought. Did you remove or install the SD card from or into the camera while it was still on? This could be a problem.

Jerry-

Yes, that is another thing I thought of. I am pretty darn sure I didn't have it on. And I tested a few times with it on to see if that would consistently cause a problem and it did not.

I know the copying and leavig them on a card and reinserting sounds inocuous, but I have repeated it and it does make all files after the ones that were copied off unreadable.

I would still like to hear if anyone else can reproduce this or if I should assume I have a bad camera???

thanks,

tom
