That should show you've created a new partition, and formatted it to vfat.

Before I continue this is what I got so far. I stopped after the 3rd line "EOF". This what showed up and I wanted to know is it safe to continue?

Code:

/home/user # sfdisk /dev/mmcblk1 <<EOF
> ,,c
> EOF
Checking that no-one is using this disk right now ...
BLKRRPART: Device or resource busy

This disk is currently in use - repartitioning is probably a bad idea.
Umount all file systems, and swapoff all swap partitions on this disk.
Use the --no-reread flag to suppress this check.
Use the --force flag to overrule all checks.
/home/user #

Now what?

So it's mounted? That's really odd...

Try this (and again, be sure you are root!)

Code:

root
umount /dev/mmcblk1

That should unmount everything. They try this block again:

Code:

sfdisk /dev/mmcblk1 <<EOF
,,c
EOF
sync
mkfs.vfat /dev/mmcblk1p1
sfdisk -d /dev/mmcblk1

Worst case, use the --force flag, just make sure you're saying mmcblk1 and NOT mmcblk0! mmcblk0 is your internal OS!

woody14619,

Ok lets say I have to use the force flag. How do I do that?

EDIT: Tried the umount and this is what I got.

Code:

/home/user # umount /dev/mmcblk1
umount: cannot umount /dev/mmcblk1: Invalid argument
/home/user #

Just throw it into the command between sfdisk and the device name.

I'm more concerned about the fact that it thinks it's in use. As root just try typing mount and see if it's listing anything for /dev/mmcblk1. If it is, try umounting that by name. (For example, it may have /dev/mmcblk1p1 mounted? But the previous command said it had no partitions, so...)

Ok woody14619,

At root just typed "mount".

Code:

devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev,noatime,size=65536k)

Isn't it mmcblk1p1 for the FAT32 partition on the uSDHC card on the N900?

If so, "umount /media/mmc1" as root, followed by the other stuff, as appropriate, should (probably) work.

Note that /dev/mmcblk1p1 is the first partition on /dev/mmcblk1 and /media/mmc1 is the directory it gets mounted to.

Edit: beer induced typo corrected for the benefit of humanity..

fnordianslip,

Did the "umount /media mmc1"

Code:

/home/user # umount /media mmc1
umount: cannot umount /media: Invalid argument
umount: cannot umount mmc1: No such file or directory
/home/user #

Hmm.. thats odd, since the sfdisk command output you showed bfore said it had no partitions on the device... Yet now it's saying it has a partition mounted. Well, this should do it for you:

Code:

umount /dev/mmcblk1p1
sfdisk /dev/mmcblk1 <<EOF
,,c
EOF
sync
mkfs.vfat /dev/mmcblk1p1
sync
sfdisk -d /dev/mmcblk1

The output the the last command should show you have a partition, formatted properly. Then a quick reboot (or open your back cover and replace it) and you should be all set.
