Hi, I bought myself a 16GB SANDISK MicroSDHC card. My laptop runs the OS windows 7 64bit. As I inserted the card into my N900 it told me the card is in a unsupported format. I reformatted it on the N900 and things seemed to work. When i connected the N900 to a computer via Mass storage mode it sometimes works to move files over to the card. Sometimes windows tells me to insert a disk drive everytime I try to access my MicroSDHC. Then and again my N900 tells me the card is in a unsupported format, sometimes it can access the data files but only plays some sec of movies and then aborts playing the file and sometimes it just works flawlessly. Sometimes I can make the card work by simply rebooting the N900, sometimes I have to format the card.

I tried reflashing the N900, yet the memory card remains unreliable.

I have used other MicroSD cards that work without any kind of problems. I of course have warranty and would send the card in, yet I don't want to send it in unless the card is really broken/corrupt (whatever the term here).

Is the card defect or is it the card reader from the N900? As I said, with another card it functioned without any problems, which makes me doubt that the card reader would be broken.


I would appreciate any answer,


Thankyou,

Fred
