MicroSD card not working. - maemo.org

AlMehdi | # 1 | 2010-08-04, 21:36 | Report

I am pretty much lost on what to do. I have read a couple of thread and tried to both format and fsck. All to no vain. Does someone have a clue on what to do or what the cause of the problem could be?

The card is a Sandisk MicroSDHC 16gb class 4 card.

Code:

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes:  dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)

Go in file manager, you can see your microsd there? Press and hold on it, there will be a format option. Did you try that ?

No idea. Can you try to format it from a Windows machine? Is the card newish?

gtessier00 | # 5 | 2010-08-04, 21:57 | Report

It did not work? What did it do?
What is the supposed size of that card?
And when you put it in a computer, how much available size do you have?
Did you get it in a retail store, or from eBay?

Plug the N900 in mass storage mode on your computer, then check if the memory card is available in my computer. if it is, right click and format?

It say the card is not supported. I wrote what card it is in my OP. I can't put it in my computer. I bought it from a ebay typ of site but swedish.. the guy who sold it had 5 of 5 stars which means he can be trusted.

try the umount command; and reboot

i think its root, then

umount /media/mmc1

reboot

could be the cover didn't close properly or the magnet behind the stand is lost. If the memory card can be read by the PC then it is nothing wrong with it. Therefore the problem is the N900 and it's back cover.
