HELP: technical info about SD card, I am at the end....

[reginald]

Hello all....
Today after a long trial I took my M8 to some official bussines and took about 40 shots as requested by my neighbors...

For them a very important happening.

I use SanDisk Extreme III cards of 1 Gb...

I took about 12 shots at an easy pace, and when the crucial moment arrived I took about 14 shots in a quick sequence, I could review them on my screen...
Taking the last shot it occured to me that the counter still was on 15, and the last 9 shots most important shots were not on the card at all.........................................

I alway erase and format my cards in camera before use.. which gives in RAW only mode 93 shots on a blank 1 Gb card ( at least in my M8)


I tried the with the card supplied Rescue programm, and to my big surprise this came up with about 54 files.
Among those TIFF files of shots that I had taken on previous occasions and were deleted, after which the card was formated.

also 9 files of today with a file extension .CUR exactly the files that I am missing...

Anybody any idea if these can be saved, and in which way? the strange thing is these files vary in size between 15 KB and 2.2 Meg


Other then that does anybody know what has happened here, I changed the card after I noticed the mishap and all did go well....I did not dare to take shots in a too quick sequence anymore..

I haven't noticed the same problem you have but the M8 seems to take forever to transfer to the Sandisk III card I have. One shot and it is 6-8 seconds before the light stops blinking. And of course you can't bring up the image on the LCD until the buffer is empty. shoot several shots in a row and it'll be awhile before you can look at ANY of the images! That's my main aggravation with the M8. Slow to dump the buffer - same as the Epson R-D1s.
Anyone have some insight on this?

The M8 buffer is supposed to be able to allow a 10 shot sequence at 2 frames per second. Just tried mine using a (2Gb) Sandisk Extreme III on DNG and it actually did 12 before it stopped - with the last frame seeming a bit slower. Dunno if that helps?

PS I just put some tape over the red LED and now it doesn't bother me anymore. The buffer is good enough to let you shoot as fast as you want in almost all conditions. I don't really care if I have to wait a minute to chimp, as long as I can keep shooting is the main thing.

That is my experience as well. Perhaps the M8 is not only writing to the SD card, perhaps it is also "thinking." With any camera me thinks "RAW" may not be as raw as many assume. How else could different digital cameras have such different images or improved noise at high ISO with new firm ware updates if the image is actually "raw" or uncooked?

It might happen if you pull out the card or battery before the camera has finished writing the buffer. A nice thing of the M8 is that even as it is emptying the buffer you can keep shooting, albeit a bit slower, to "top it up".
