Jo,
Thanks for the info. As you can imagin I have done everything I can think of to try to get this working again.
It's one of my Olympus XD Type "H" that I use in my mju1030SW which is my "always with me" camera, so it gets a lot of use.
I used it like most people do, straight out the box in the camera and off you go. Has anyone ever read the instructions for a memory card.
Well you may just want to:
"Like all flash memory, the xD-Picture Card has a limited life span, and will eventually become incapable of performing WRITE/ERASE functions after long term use"
So what constitutes long term use

They only have a 2 year warranty so it may be a good idea to get new ones now and then.
Some data on failures would be nice to know about, so we can make a judgement call on this. So if anyone has such info., please share...
