Cheap SD Cards
Sunday I did a quick sunset shoot. Out of 46 images, several had weird colors in unusual portions of the images. Magenta, purple and blue. The weird colors did not show up when being viewed in Windows explorer, but were evident in LR. The strange colors did not show up in Bridge, unless I opened the image in ACR. The weird colors were quite evident in the On1 browser and in Capture NXD. I must add that more weird colored images showed up when viewed in the On1 browser, than with any other method. My conclusion is that the corruption was caused by a bad card. I am not interested in placing blame. I am interested in the problem not recurring. For the first time since I've been shooting digital, I used a card other than Lexar or Sandisk. Fortunately, those shots were just intended to be background sky shots, so i had no real loss. It is however the first time I have had files that were corrupted. I am writing this to blow off some steam, and remind others who may have been getting away with using cheap cards, that they have been lucky. -- PeterN |

That effectively turned it into a read only card which, after much trying, proved to be unrepairable. So that was a $65 card down the tubes. I still have one more of those, and four Lexar 32GB 150MB/s SDHC cards along with a whole bunch of Lexar CF cards. All my other CF cards are Sandisk, and I have just bought 2 more Sandisk Extreme Pro 32GB 300MB/s SDHC UHS-II U3 cards. -- Regards, Savageduck |

I bought a Nikon P&S in Glasgow for my niece, I don't remember now the exact model, but it was 50 pounds IIRC. It was a nice shop near the Clyde river. I bought a cheap card (5 pounds) but it didn't last more than a year. I tried in vain to recover the images, and my niece wated them because they went to the mountains to see the snow.From now on I'm always getting brand name cards even if they cost a couple of euros more.My Nytech takes a 2GB card only, but I found a shop in the 'net that still had them. It's now on its third card and on its third set of batteries. --- This email has been checked for viruses by AVG. http://www.avg.com |

Sony, Kingston, Toshiba, Transcend, etc., have all branded or made decent cards. The files are digital so if files written to the cards are identical when read from them then the cards are oki and won't affect the colors of your captures. -- teleportation kills |

Apparently, the camera has a "feeler", checking to see if it can drop into that space or not. If not, it's a R/W card! So I carefully put some epoxy in that space, and am still using the card. I just can't use the lock. -- croy |

So it would be best to run a check with a known good performing card to eliminate possible issues with the camera. What was the brand of the card in question, what was its rating, and which camera were you using? D800, and a Delkin Black. I complained to Delkin. They are sending me a reader, and requested that I test the card with that reader. The shot you see is a ten shot multiple exposure. I was testing to see how much time was needed between shots, to get a similar effect to a long exposure. despite the corruption, my conclusion is that it can be done. In a calm bay it takes about 2.5 seconds between each shot, for a ten shot exposure. -- PeterN |

I am writing this to blow off some steam, and remind others who may have been getting away with using cheap cards, that they have been lucky. Ran into this a few years ago with a slow card in a GoPro. Tossed the card in the trash. I have bought only premium-grade storage since that time. -- I agree with almost everything that you have said and almost everything that you will say in your entire life. usenet *at* davidillig dawt cawm |
