mini sdhc -- m3 works, xp & w7 says not formatted

Everything was fine with the card yesterday.

Since the sd formatter was recommended (sp?) I decided to backup the card and reformat it using this tool. All went well and I copied the files back to the card.


The quick disk check was quite a bit faster now and everything seemed to be in order so I decided to put a few homebrew games on there. After a bit of trial and error
I was able to find a few games that I thought my son might like. Everything seemed to be fine yesterday....


Today I was going to put a couple more games on the card for him and now windows (7 and xp) keeps saying the the card is not formatted. However, the card still works fine in the M3 real just not on the pc.


I've tried to format the drive (last resort) using the windows format tool but it says that it cannot format the card. (quick and full formats)



Unfortunately, I deleted the backup that I had made of the card and the only backup I have now is two months old...


Is there anyway to get the data off the card? I know it's there bc as I said the m3 can still read the card (quick disk check doesn't report any problems).... wth


Please help!


Thanks
Richard

 

That's what I used before all of this started...

I know a quick format in windows doesn't really delete the files. So it may be possible to recover the files after a format.

Will I be able to recover the files from the card if I use the panasonic formatter again? I'm mainly concerned with losing the sav files....

Thanks
Richard

EDIT:

I've tried using:

The usb card reader that came with the m3
I've also tried two different cameras
---one couldn't read the card at all
---the other reported the correct free/used space, but wouldn't show the files on the card

 

That was it.

I replaced the usb reader and it works now.


Thanks for the help!
