Sd card contacts cleaner Pc#Now it's working fine (so far) with the 16GB SD Kingston HC card, but not with the 32GB Sandisk, which appears as locked when attempting to use with a Windows XP PC (yes, I know, dinosaur OS). so I squeezed some drops of isopopyl into the card slot and held it upside down straightaway, so that the isopopyl immediately flowed out - I did that to prevent ingress of the isopropyl further into the case. SD card still not recognised, no oxidisation was visible on the paper. so I cut out an SD card shape out of a thin piece of plastic (one of those credit card sized things that SIM cards arrive in), cut some paper to cover it at the end (folded over), stuck it to the plastic with gaffa tape (other end of the card, which wasn't going to be inserted), then soaked the paper end with isopopyl (which was folded over the end of the plastic SD card shape), and gently inserted into the card slot and wiggled it about. I can't abide the interminable delay of 20 minutes or more of trying to get the camera to recognise a SD card, shortly before I have to take photos. ![]() ![]() I was in sustained rain for several hours, and although the camera seemed dry within it's foam case, the camera rucksack wasn't - the problems got worse after that, but it could be coincidental.Ĭlick to expand.Nothing has changed - no firmware updates have been available for years. The reason why I've tried isopropyl, is because I suspect that the camera is damp within. Whether or not this works is unclear, because the camera recognises 16GB cards after about 20 or so minutes of insterting and removing cards anyway (if I'm lucky). Does anyone know what is causing this issue, and if I can fix this myself at home somehow? I've tried cleaning the contacts within the card reader using isopropyl alcohol - I don't touch the contacts directly, I put a few drops onto a dead SD card and insert insert that into the camera and remove a few times to clean, then try a card which I know works, once it has dried. Once it does recognise a card and allows a format, that card usually works fine until I remove the battery to charge, take that card out (which is when I need to keep taking the card out and reinserting it, over and over again, until the camera recognises the card) or I leave the camera unpowered for a week or two. I've tried taking out the battery and card mutiple times, and eventually this works, but only with the HC cards up to 16GB in size - previously it would recognise 64GB cards with no pronlems. I wonder if someone could help? My 650D is fantastic, but lately it has started being unable to recognise SD cards, that it previously had no problems with. ![]()
