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

Try to format it on your computer to FAT32, that should solve it.

hi, thanks for the answer. Thats the thing it actually doesn't work. the n900 tells me that the sdhc is in an unsupported format. Its all very weird and i've formatted the card so often without any results. I just hoped someone knew some vodoo trick that could fix this. Do you think its a hardware defect?

Sounds like the card might be trippy - can't tell without the card in my hands to test myself. Generally, if 2 card readers on the PC can't read it reliably, the card is the error.

Alright thanks. Thats what i thought. I have just never had a memory card that has malfunctioned, so i wasnt sure. I'll send it back and hopefully ill get a new card.

cheers, fred
