JimmyCheng Posted January 13 Share #1 Posted January 13 (edited) Advertisement (gone after registration) I am not sure if this has been brought up before, cuz I can't find any. But this is something truly scary. I clearly remember taking two certain shots yesterday morning, even reviewed them afterwards. Then the camera froze at one point in the afternoon when I took a few more shots. Turning it off does nothing so I had to pull the battery out. But when I was reviewing my photos today, I found that two frames (not the ones immediately before freezing but ones taken in the morning) were missing, as if being deleted by myself. It's not showing up on the sd card at all even when connected to my Mac. I had occasional freezes before but this is new, and it renders this camera completely untrustworthy. I thought the freeze issue was addressed in the latest firmware. Edited January 13 by JimmyCheng 1 Link to post Share on other sites More sharing options...

No I just found this out, and this is really rather alarming. Freeze is one thing, file go corrupted or missing is serious. Link to post Share on other sites More sharing options...

Freeze is one thing, file go corrupted or missing is serious. Two of the M11s I went through gave me intermittent unreadable DNG files, but clearly labeled as such. Who knows if other files went missing, unlabeled. Might be worth downloading a trial of Disk Drill to see if there's anything there that you can't see. 1 Link to post Share on other sites More sharing options...
jaapv Posted January 13 Share #5 Posted January 13 Is it on the latest firmware? The missing file problem was solved a while ago by an update as I rewcall. Link to post Share on other sites More sharing options...

I thought the freeze issue was addressed in the latest firmware. Just remember to reset the camera after updating it every time, something can always show up in incomprehensive ways. it should fix all freezing! Sometimes is as simple as checking all the storage on the camera and making sure it didn't go somewhere else, maybe a new folder? on earlier firmware, I had an issue that the SD was not recognized completely, and it would go inside the IN memory. 19 minutes ago, jaapv said: The missing file problem was solved a while ago by an update as I rewcall. The overwritten photos were never an issue on M11. Just SL3 and Q3 Sometimes cards are a problem, It has just been reported that the Sandisk Extreme Pro V-60 card is not compatible with some Canon cameras, and corrupt files!

JNK100 Posted January 13 Share #8 Posted January 13 This is likely to be a faulty card. Do you format in camera ? Link to post Share on other sites More sharing options...
JimmyCheng Posted January 13 Author Share #9 Posted January 13 1 hour ago, _tc said: that's highly unusual behavior. it's hard to imagine that waiting all day the write buffer wouldn't get cleared out. is it safe to assume you confirmed the files were also not on internal storage? no I never use the internal storage.

It's a sand disk card that is relatively new and I don't shoot a lot (so very little usage). Link to post Share on other sites More sharing options...

It is best practice to format a card each time before reusing. Deleting can cause problems. 1 Link to post Share on other sites More sharing options...

I only format when I use on a new camera. And I have never had any issues until today. If that is an excuse by Leica I won't accept. Link to post Share on other sites More sharing options...
jaapv Posted January 14 Share #14 Posted January 14 Seriously. Standard and strict procedure for me: Use Bridge to ingest a card to the working SSD, at the same time back up to the backup SSD and afterwards format by SD formatter before popping back in the camera. Format second card ( in-camera backup( if present)) I never delete files in the camera, culling is for in the computer. That way I avoid card errors and fragmentation.

BLR Posted January 14 Share #15 Posted January 14 When you delete photos in camera, the camera is not deleting the file. It is allowing the camera to overwrite new files to the card. Formatting actually erases the files. Link to post Share on other sites More sharing options...

JimmyCheng Posted January 14 Author Share #17 Posted January 14 50 minutes ago, _tc said: this isn't specific to Leica it's just general best practice. I think it's speculative that it's related though. If that is the case then the card will only have potential issues if it gets near full a few times. But I have in total only shot couple hundreds photos onto this card since last formatted. In any case, I'll see if I can replicate this. 1 Link to post Share on other sites More sharing options...
jaapv Posted January 14 Share #18 Posted January 14 That depends on the format. Quick format only marks the files as “empty space”, overwrite format actually overwrites the files with random zeros and ones. In-camera format is always a quick format, although M8 and M9 actually offered an overwrite option. Formatting removes errors. An error can occur at all times, even with file#1. And lead to data loss. Link to post Share on other sites More sharing options...

It is allowing the camera to overwrite new files to the card. Formatting actually erases the files. This is not necessarily true. While you can use something like SD card formatter to do an overwrite format -- the one that takes many minutes to complete -- a standard format only re-builds the directory structure with is the rough equivalent of deleting the image. Unlike others, I (almost) never format my card. I use a script that copies images from card to computer, compares the copy to make sure it is accurate, then remove the image from the card without going through the system or card trash folder. This has worked for me for decades. When there is an error it is because the card is going bad, not because I didn't format the card every time I transferred images. I've had two or three cards go bad over the years. More if you include cards used in other (not camera) devices. Perhaps I've just been lucky. With only one data point there is no way for me to know.
