How to format data on SD Card partition - Ubuntu

[Hurdy]

Hi everyone,

Firstly thank you for taking the time to read this.

I want to update my version of Angstrom to the latest version. My SD
Card has 2 partitions, one is an MsDOS for the MLO & u-boot.bin files
etc and the second ext3 partition for the angstrom image.

With the MsDos Partition I was able to just delete the files via the
ubuntu GUI. This cannot be done for the ext3 partition where it flags
the errors "The folder "folder_name" cannot be handled because you
do not have permissions to read it."

I have mounted the SD card partitions with no trouble. The partition
in question is mounted at location "/mnt/sdf4".

Any advice how I can delete the files would be great. I am a newbie to
the linux way of things.

Many thanks,

Rob

No problem. First of all you need to figure out the device node (file in /dev/) associated with ext3 partition. You should be able to figure this out by simply executing "mount" in a terminal window. For me, it is typically /dev/sdd1..."mount" shows the following (in addition to a bunch of other stuff)...

# mount
...
/dev/sdd1 on /media/usbdisk type ext3 (rw)

If already mounted as you mention then unmount the partition as follows...

# sudo umount /dev/sdd1

Then format using mkfs...

# sudo mkfs.ext3 /dev/sdd1
