umount

for obscurity reasons, i guess

Whoops - I think I need new glasses!

I can read the card and the files on the n900 but can't delete them.
When connected to PC in usb mode the card doesn't show, but does in a usb adapter. Clicking the properties of the folders in the adapter shows them all as 'read only' and whilst I can remove the 'read only' check mark it's still there when I click properties again.

I found this on another thread with similiar problems:-

From xterm I signed in as root and remounted the filesystem in
/home/user/MyDocs as read and write.

Code:
mount -o remount,rw /home/user/MyDocs

Is it possible to remount the SD card in the same way?
clutching at straws but you never know, then I might be able to manually delete all and reformat!

Try to change the partition type with

Code:

sudo gainroot
sfdisk -c /dev/mmcblk1 1 c

Then reboot. This time it is 1[one]

Ok done that but no change, still all write protected!

Could you help with the right code to try? ie. mount -o remount,rw /home/user/mmc1?

I know that's not right and i'll have to do the gainroot thingy but as you can tell, I really have no idea!!

This will unmount the partition and then try to mount it rw

Code:

sudo gainroot
umount /dev/mmcblk1p1
mount -o rw /dev/mmcblk1p1 /media/mmc1

or if already mounted you can try

Code:

sudo gainroot
mount -o remount,rw /dev/mmcblk1p1 /media/mmc1

Thanks for all the help, I've been playing with the liveCD on an old laptop and you were right, very easy. In fact I liked it so much that I've installed it along side windows but i think I'm going to just replace windows with it.

Still can't format the card though and tried a few commands in the terminal on the laptop - no joy...

ready to give up now, I think i've wasted mine and everybody else's time enough with this.
Just have to use the n900 without the card..

Thanks again to you and everyone for the help.
