Fujifilm Finepix V10
You can send your camera to FUJI and pay $120 or you can try this at home for zip...it worked for me!
I to have had focus error problem with my Fuji A310 camera and after much frustration and phone calls i decided to try a different approach to this problem........
I FORMATTED my 64mb XD card in my computer memory card reader using the FAT setting and guess what my camera is magically working now.....
Why couldn't FUJI helpline have told me this when i spoke to them, answer because they were to preoccupied in trying to sell me a new camera!!!!!as if, there service is nonexistent and proven!!!!!
Why is it called a HELPLINE then should rename it "FUJI RESELL LINE" hey....or maybe "FUJI NON HELPLINE"
Also formatted 16mb card same way and working also, maybe i should get a job at FUJI hey only problem is i wouldn't endorse there products, very good picture quality in an unreliable package..suggest any better brand for next time nicoleashley ?
ADDENDUM TO PREVIOUS SOLUTION FROM JIM PINEAPPLE---
After you have formatted the XD Card in your computer card reader reinstall card to camera and using the camera software format the card again, this prepares the card to accept it's normal data...
P.S. I called the Fuji Ha Ha Helpline here in AUSTRALIA and informed them of this procedure so as to help all the poor souls like us that purchased our only Fuji digital camera, as if they didn't know already,
and the moral of the story is as of 27-8-2007 Fuji would be absolute Mongrels to not inform via there helpline how to fix there very common "FOCUS ERROR" problem which is common across the Fuji digital camera range, just google FUJI FOCUS ERROR....
