Using my loved N800, my 2 gb SD memory card got corrupted using the external slot. I was trying to fix it with many methods, format in windows, linux, using gparted, partitionmagic, the toshiba formating tool, etc.

Finally I read somewhere that someone fixed it using a Canon photocamera, and I decided trying with my Panasonic camera and with my mother's Sanyo. But nothing, no success... I was about throwing away the card, when today, my sister brought a Canon PowerShot A520 camera, I tried once again and surprisingly it works!!! My SD works perfectly, I tried to fill it entirely with music, videos, images, playing and viewing those files, delete them and works like a charm!!!

So people, If you have the oportunity to format your cards with a Canon camera, try it! you will not loose anything!

Well, "formatting a card" will of course erase all the data on the card (for thosee newbies out there). But of course if your card is irretreivably corrupted, trying to reformat in other cameras/devices certainly won't make things worse. When my 8GB SDHC card got corrupted (also in the external slot), I used my Treo 680 to restore it to working order.

Indeed. That's me. I also explained why my card would not reformat elsewhere: the partition table was corrupted. That is what the camera fixed. I suppose that it should be possible to fix a card using linux fdisk as well, or even dd if you have an image of the first sectors of the card.

You probably can "repair" damaged partition table with fdisk, both on Linux and Windows.And well, if ONLY partition table has been damaged you even can get your data back.All you have to do is to fill partition table with right values, then you'll get your filesystem back and working.A bit tricky\advanced operation but well, this also sometimes happens on regular HDDs sometimes.
