So have we seen this defect before?

Hey--

 

What do you think? Card or M8 (or current 2.004 firmware)?

 

I just got back from WPPI and I bought some brand-new 4GB Hoodman SDHC cards. I was having trouble with the one Sandisk Extreme SDHC 4GB so I thought I'd try the Hoodman.

 

These look fine on the M8, but corrupted on the card according to C1. Of course I'll revert back to 2GB non SDHC cards, but I don't think I've ever seen this before...but if anyone else has or has seen a solution, please chime in and let me know!

(and yeah, the pix are no greatness or anything, but they sure illustrate the problem. If I was a betting man, I'd say it looked like some weird EMF banding... OTH, the way the M8 writes to the card could be the direct issue).

Jamie--

Tried transferring the files again from card to computer?

 

I had a similar problem once, and the second time I imported the files, they were fine.

 

Good luck. Hope it works for you.

Howard,

 

Tried transferring them with 2 different card readers; same deal. Tried opening them on the actual card; same deal.

 

I mean, I suppose it might be the card, but I kinda doubt it, since both Sandisk and Hoodman SDHC cards are going south. It doesn't seem to affect the regular SD cards, but my real question is if my camera is somehow hardware limited and won't work with SDHC cards regardless of firmware?

Jamie, as a last resort I'ld try reformating the cards on a PC. Right click on the icon. Select Reformat. Make sure you use FAT 32 for SDHC cards. Just to be even safer, reformat them again after reinserting in your M8. I regularly use 16GB cards with no problem.

Does the error occur with both Raw images and in-camera JPEG?

 

If the problem were the card, I would expect marker errors when they are opened. RAW files are uncompressed, more likely to allow bad data like this. JPEG: if it were the card, I would expect marker errors.

Shouldn't be related to card size. SDHCs work fine for many of us.

 

Only thing left is to send examples of the files to Leica, I think.

 

Did this occur while another file was being written to disk, perhaps? Is there something similar about the situations in which the stripes appear?

I have stayed w/ 2gig cards, always worked fine. I actually don't mind reloading cards every 179 images (raw only). If the error doesn't occur w/ non SDHC cards, then it may well be the camera. The probability of several cards having the same or similar errors is very slim, more than likely a compatibility issue.

Jamie - I think you really should send these files to Leica. To me it seems like the electronics on the motherboard are dying.

 

Thanks Jaap--and thanks everyone else--for your advice. I'll send the files to Leica; I suspect they're going to tell me to send the camera in :(

 

I hope I get it back in time for the summer wedding rush..

So no similarity with my "Jesus stripes" in regard to other files being written when the problem file was snapped?

 

As I mentioned in that thread, on seeing the files, Leica immediately diagnosed the problem as the main circuit board, as Jaap suggested.

 

I don't think the other person who reported similar stripes to mine ever reported what the solution to his problem was, just that Leica had agreed to expedite handling.

 

Your stripes bear no resemblance to the Jesus Stripes; I'm only asking whether you discovered some other common aspect among your damaged files.

Howard,

 

No--there's no relation to the way I was shooting and the defect, except for the SDHC card(s).

 

I admit at first I was banging off a few quickly to see if the Hoodman SDHC cards made any difference at all from the kind of flaky Sandisk SDHC cards; I also shot very slowly as well and have the defect.

 

It's very odd, but I think Jaap is right: the files need to go to Leica.

No, I'm running the newest firmware. I was just mentioning that the I have seen a similar problem before. I'm sorry for wasting the forms time. I'll just keep quiet.

Jim

 

Hey Jim--not a waste of time at all. Did upgrading to the newest firmware fix this? Do you think it was a card issue?

 

I'm curious, though I still think the M8 is going to get a trip to NJ...

Jamie--I hate to keep butting in, but have you sent them copies of a couple of the files? It took them less than 24 hours to respond when I sent my stripes samples.

 

OTOH, my camera is not expected to be repairable (parts shortage) before the end of April, so getting that initial quick response may not have been that helpful in the long run. :p

 

 

But if your stripes occur only on SDHC cards, it may be a completely new problem??? How many examples did you have out of how many frames? Was it cold or were you in a solar storm? Are your stripes repeatable?

 

Oh, perish the thought, but have you tried opening the DNGs in another RAW converter?

 

 

Getting curiouser and curiouser here. ;)

Hey Howard--just for your curiosity...

 

Yes, I've already contacted a couple people (distributors, someone in Leica NJ) about this issue and sent them JPEGs of the DNGs. Though I haven't heard back from them yet, I have every confidence they're working on this in the background.

 

OTOH, my camera is not expected to be repairable (parts shortage) before the end of April, so getting that initial quick response may not have been that helpful in the long run.
One of the reasons I haven't heard back, I'm sure, is because I also asked how long it would take to repair, given my busy season is about to start!

 

But if your stripes occur only on SDHC cards, it may be a completely new problem??? How many examples did you have out of how many frames? Was it cold or were you in a solar storm? Are your stripes repeatable?
I haven't had a chance to reproduce it yet, and I probably had 10 percent of 100 frames affected. It was temperate outside, the camera was affected when both "cold" and "warm" and I have absolutely no idea if I was in a solar storm :D I was in Las Vegas with a gazillion other photographers. The stripes haven't been reproduced on any other card, but the lockup and write issues were on the Sandisk SDHC as well.

 

I'm thinking that there may be an old electronic part or part of the system in my M8 that is failing given the larger capacity and faster write times of the SDHC cards. With the 2GB slower cards, I've never seen this, though there are still write problems that require pulling the battery every now and then.

 

Oh, perish the thought, but have you tried opening the DNGs in another RAW converter?
Yes--ACR will either not open the file or reproduces the stripes on open. It's definitely not C1 :D

Yep--it's weird for sure :)

Agreed; makes sense.

 

Since they responded to my problem almost immediately--saying, "I showed your files to the head M technician, and he said the main board has to be replaced"--and are taking more time on yours, I think you've probably got a new one for them.

 

Glad you've got the workaround of using only SD cards; I hope the problem doesn't spread there as well. :(
