Originally posted by Markovo My K-1 has the same white dot issue starting from 1min exposures and above. Calibration does not helped, so the camera was sent to France for service.

oh man...feel sorry for you.
When I discovered my camera was suffering the WD issue, I had a few email exchange with French Ricoh support with sample pics, then had to talk directly to the official repairshop that Ricoh redirected me to.
there, They had no clue how to deal with this issue, I forwarded them email exchange, this forum specific thread and some other french forums reporting the issue. After a week of phone calls etc they told me that I can send them my camera but they wouldnt know what to do, that they will need to check a couple things ...but they had no clue what to do ...I decided no to send the camera and waste my time.
It's a shame the way Ricoh handle this issue, at least in France.
