How fragile are SD cards
You have an SD card, you re-charge the device ( with the approved re-charger) the SD card fails.
You buy another card.
How common is this?
I need to buy yet another 2GB card but I don't know why the one I had died after 4 months in a Cybook E-Reader when this wasn't heavy use (That would have made some sense.).
SD cards used previously : PNY, Kingston and ADATA.
How do these cards behave in other devices, your camera for instance ?
How long do they survive ?

How fragile are SD cards
Do you move the card about to transfer files or is it a permanent fixture?
Any other problems with the device?
Any chance you can check with a volt meter to make sure the charger is not over charging? (unlikely as the internal circuitry should dictate what voltage is supplied to the SD card)

Hi rj,
The SD cards are, essentially, my data bases and they're movable.
All reference files for "look-up" go into the the reader's memory and the books/files themselves go on to the cards.
Unless they're DRM books, those have to be transfered with the card in the Cybook but that hasn't been a problem so far, I can use a usb reader to transfer the books.
The "death" only happens, when the card is in the reader during recharging but it's really random, no pattern at all.
The reference stuff in the reader itself is unharmed.
The recharger was checked, it's fine, but I now have several hundred books plus other documents on each card and having to transfer them again is no longer a minor annoyance.
If you know of any SD cards that don't die randomly, all the ones in the OP have at one time or another, I'd really like to know. They have to be 1 GB or 2 GB size.

How fragile are SD cards
I am still using a 6 meg SD card that has been in a Palm 130 for about 7 or 8 years. Its outlived a battery failure and still works fine. I use a SD memory chip for backups, in my camera, MP3 player another Palm I have and have never had a failure of any kind. The devices that uses the SD chips are plugged into their chargers and that has never caused a problem. I would think there is a problem with your device or charger.
I think I would reformat it and try again.

The charger was cleared I was hoping it wasn't the Cybook since I'll have to FedEX it for testing.

SD cards burn out through use, and a lot.
In the photography world we are forever buying them, some high end DSLR's come with 2 ports for SD cards and photos are saved to both, so if one burns out you have a backup there and then.

I'll try a home-made variation of the duplicate idea for my SD cards, it makes good sense and I wish I'd thought of it!
Thanks!

Buy cards that come with a good warranty - brands that have known good RMA policies.
