Can you open the problem DNGs all the way into Photoshop?Yes
If you reconvert the DNG files (send the DNGs to the converter) does it produce a new DNG with no problems?In fact if I just move or copy them they seem to fix themselves. Reconverting also seems to work.
What software and hardware are you using?Dell XPS M1530 Dual 2.2 GHz with 4GB RAM running Vista Ultimate SP1
What version of the DNG converter?18.104.22.168
How did you make the conversion?Folder conversion using Converter with full size preview, lossless compression, preserve but not embed RAW
Did anything get transfered over a network?No...all the images, source and destination, are on an external USB2 drive.
What applications touched your files?The OS for copying off my Epson P-5000, Bridge and DNG Converter...that's it.
Were all the DNGs made at the same time, with the same settings?Yes
Are the problem files locked? No
If on Mac, have you run permissions repair recently? N/A
Save those corrupted files- they may offer a clue.Mmmm...only one left since I tested moving one of them and it seems to have self corrected. Th other one is still there with the problems.
PS: I did notice that I was having some problems keywording in bulk on the dng's too...although I have not investigated that as thoroughly yet. This could well be to do with the fact that I am upgrading my keyword hierarchy and a bunch of stuff is moving around which is giving Bridge (and me) a headache...it pulls back the old path even though the keywords still exist on a new one. This might be something worth emphasizing in the future...you really ned to pin down your keyword backbone early so changes are just adding leaves not transplanting branches!
