It did but i deleted some stuff then formatted the card, doesn't show now though.

Any advice?

Cheers

Did you format the card via the N900 or via your computer?

pc .

Same for me, won't show my SanDisk 4gb MicroSDHC card when inserted into the phone. Any pointers on how it could mayhaps be manually mounted and reformatted on the phone?

I have a 16gb SDHC which sometimes shows and sometimes not.

I'm waiting for my 16gig card to turn up so haven't actually tried using one yet, however.

It's always a long shot.. Have you tried opening a terminal and running the "dmesg" command?

This will show you the kernel message log. After you insert a SD card, some information should appear (try running once before and once about 10 seconds after inserting a card)

I can't recall messages off the top of my head, but post the last 20 or so lines after putting the card in. That will at least tell you if the system is seeing the card, even if it can't use it..

mkdosfs is a console command tool that will create a file system on a device like an SD card.. You'd need to know the correct device, I can't tell you what that would be.. but it should be in the dmesg output..

dmesg shows
"error -110 whilst initialising SD card" for me

Removed baterry sd and sim for 30 mins, all is good in the world again.

Hope this helps.

If you have another phone that accepts microSD does it read that card? If it's a Nokia and it does, try formatting it in the phone.

Bad sector size ... reformat on pc- do a full format and leave default sector size
