I transfer the files by putting the CF-card in a PC-CARD adapter inserted in laptop (IBM thinkpad). I copy the files to a special 'images' partition there. Afterwards, I copy the new images over to my Photoshop system over a local area network. That is the first time I can look at the RAW image content and notice the corruption. Since a few people have mentioned some problems due to copying, with the original image being OK, I will retry that step. The last image that turned out to be corrupt is still on the 1Gb Sandisk CF-card so I can retry. I will also install the Pentax image browser on the laptop to see if it is Ok there ... Thanks everyone for the tips. Regards, JvW If a second copy also fails, I might try to use the USB connection directly from the camera.
