MicroSD killed The D600 works fine for some weeks. Then the battery is empty within 4 hrs in standby, access to the SDcard is "forbidden" and - when checked outside the phone - the SD is damaged. Its now my third 1GB (a KINGSTON), my 2nd battery pack ... SAMSUNG is telling me that my phone is okay! I like this phone but it should work.

Maybe the solution works fine for the d900. For the d600 you have to press the camera button THREE times.

Here is the only way that I have managed to get my Toshiba 1GB card to work with a D900 pretty much all the time. If this doesn't work, please don't hunt me down! but its been doing me fine (repair guy)and saved me from wanting to "hurt" Samsung for being so very unhelpful (ish). Anyway..... I switched the phone to Mass Storage (Settings - Phone Settings - USB Settings). I then removed the card, and then re-inserted it - but then immediately hit my camera button twice to take a picture. The phone says that the card is inserted and when I go into it it can be accessed. This fixes the problem about 95% of the time I have tried it. I am an IT Technician and I am fully aware that none of this makes sense but I had to post it so people can try because I don't believe that being told to go and buy a Sandisk card is very helpful. And with all the fake ones floating on Ebay you could get even more screwed. good luck!!!!!!!!!!!!
