Formatting microSD card error

Question

I'm trying to format a SanDisk 16GB microSD card but when I do I keep getting the following message: One or more partitions are busy on /dev/mmcblk0 So my question is how do I correct this so that I can properly format the card? I've tried formatting it with GParted but it never makes it past the second step. Any help is greatly appreciated.

Thanks

Answer 1

try umount it first. Use the new utility that comes with ubuntu , its name is disk utility or something like this.

or try open a terminal and do

sudo mkfs /dev/mmcblk0 -t ext3

or -t vfat if you want to use it on windows

Maybe your Micro SD Card is broken. It's possible. Random physical problems recieve random error msgs.
