First time this has happenned:

D40, Sigma 50-150 f/2.8

Took 44 photos at the weekend, transferred them to laptop with Windows 7. I can view all of them within Windows picture viewer + raw plugin (thumbnail and full).

But when I tried to open them using UFRaw prior to GIMP editing, approx. 5 of them would refuse to load. UFRaw starts up, the green bar at the bottom goes 75% of the way and then an error message comes up stating file couldn't be open...possibly corrupt etc. UFRaw then crashes.

I have:
Retried transfetting from camera to laptop.
Copied photos from laptop to different PC with exact software via USB stick - same issue. (not tried transferring photos directly to PC though)

Everything points towards corrupt files, but I don't understand how because I van view the photos fine on the camera and Windows itself.

Any ideas what could be the problem?

I'll add that prior to shooting, I didn't reformat my card, so it had photos from 2 weeks ago on. I am not aware that this makes a difference. Photos aren't that important so not too worried - just want to know how to avoid it in future.
