nullspace Posted June 20, 2007 Share Posted June 20, 2007 I have a broken 2GB sd card. It still functions but the slide "lock" switch and corresponding conductor fell out and I am stuck. I am pretty sure it's an easy fix as all I'll need to do is solder some pins of the chip together. I was wondering if anyone has a image or knows which pins I need to solder. I will scourge the web for answers until then. I would do it myself but have no other sd cards. Quote Link to comment Share on other sites More sharing options...
digip Posted June 20, 2007 Share Posted June 20, 2007 I would copy the files off in the meantime. Be sure to back them up whatever you decide, as heat from trying to tin an sd card may destroy it. Best option is just to buy a new one. They are so cheap these days, you can probably get one of the same size or larger for about 20-30 dollars and your better off with a new one at this point if you can not write to it anymore, but only read from it.

elmer Posted June 20, 2007 Share Posted June 20, 2007 Yesterday at Wal-Mart I found a 2GB SanDisk SD Card for $27.88. Get one of these and transfer old files to it before trying this. Quote Link to comment Share on other sites More sharing options...
VaKo Posted June 20, 2007 Share Posted June 20, 2007 I know that a bit of tinfoil and some bluetack will fix this if soldering is daunting. Quote Link to comment Share on other sites More sharing options...
nullspace Posted June 22, 2007 Author Share Posted June 22, 2007 Hey I am not really a newbie at this. I have backups and plenty of SD cards. I was curious if anyone new the schematics of a SD card. Plus I have a variable heat soldering pen and a stereo microscope and a BS in computer engineering, so I am ready to try it out. I ask mainly because I looked on ggogle and ended up with a link to a messed up pdf file that was suppose to be the data sheet. http://www.alldatasheet.com/view.jsp?Searchword=k9k8G08 the flash memory is samsung K9K8G08U0M Quote Link to comment Share on other sites More sharing options...
natural_orange Posted July 4, 2007 Share Posted July 4, 2007 IF your looking to have fun then i would say go for it. But if your looking to salvage a SD card then your wasting your time. I would just crack it open and look at the contacts and trace them back to a point that is solderable. you might be able to find some really small switches that you could use to replace it, or just hardwire it as unlocked.
