None of this makes any sense to me.
==>> It's weird because I do have some experience with both SX110s ... I created, renamed and erased badpixel.bin a few times to test that they did what they were intended to do and all's fine. BTW, yesterday before noticing the corruption problem I did check same on the S90, and that worked. That is I first inspected a shot w/o badpixel.bin and then with, and I got the expected results.
Since creating badpixel supposedly triggers this problem, does deleting it make it go away?
==>> Good question. Before I do it I guess that it won't. Here's what happened. I deleted the file, ran chkdsk (passed), and the answer is: no, the problem is still there. NEW: Next I put the tab in write protect so CHDK is not loaded and problem is still there.
Why all this stuff with "tethered" or not ? If it's caused by badpixel then just
1) fresh format + install
2) create badpixel
3) restart and see if the problem happens.
==>> Please reread carefully my original description. As a reminder, "tethered" means "connected to CHDKPTP and running." Your 1,2,3 is what I did, I preceded {Create badpixel.bin} by taking a few shots first to verify if everything works normally and it does, until badpixel.bin gets created. The bottom line is it doesn't matter if the preceded test shots are taken "tethered" or "untethered."
Badpixel generation takes two pictures. Is it possible that the black screen you are seeing is in fact the last image taken by badpixel ?
==>> Good point. Your idea prompted me to PAGE through the images (which I had not done till now) and yes indeed you're right all my other shots are there and so the two black images are there. Correct.
So therefore the "No image" condition is likely a corruption that happened later in the day probably when I began using CHDK RAWs. For example, I noticed that RAWTherapee didn't recognize the DNG 1.1 and one of my first missions was to investigate this when I got trapped by the "No Image" corruption. So while this is a good step, it's not resolved yet because I have not yet recreated the original problem.
If you switch to record and back to play, do you see the images ?
==>> Of course yes thanks, but I have to page because the 1st one that comes up is indeed the last dark image taken by Create badpixel.bin.
Badpixel takes some memory, which might cause problems if the camara has very little free RAM. However it shouldn't be loaded unless you have DNG 1.1 enabled. You can check free memory in the misc menu.
==>> Just to be sure: Free 892 KB, CHDK: 252KB.
==================
So I declare *both* SD cards as not corrupted yet. Now I will start with the RAWs again this time keeping a careful eye out for "No Image."
