Originally posted by Barnster I had the same problem with my K100D with a new SDHC 4GB card ,but I was advised by a few Pentax Forum members to update the firmware to version 1.02 from the Pentax website.It now works like a charm.
I wasn't aware that I had a problem.
Th 4 GB card works in my K110D astro camera, the one Pentax upgraded when it was sent in for a user caused repair. It won't work in my K100D because I chose to not upgrade because on occasion I like to use Remote Assistant. The K110D is clicking right beside me since I'm typing from my observatory as the camera records Messier 14.
Soon the ISS will pass over and I will appreciate having a lot of memory space.
I filed the broken tab fix some more and now the card will pop out normally. I still will keep it as a spare. Like Thesorus I don't want any superglue to fall off inside the camera.
