Hi All
Hope some one can help me.
I have just built a new system and have installed windows and ubuntu 9.10 64bit.
Have installed EXT2IFS but windows keeps asking me to format the drive
chris@chris-desktop:~$ df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 15116868 2957076 11391888 21% /

chris@chris-desktop:~$ sudo fdisk -l

/dev/sda6 3825 60193 452783929+ 83 Linux

Partition table entries are not in disk order

I think I need to unmount what gparted tells me is sda6 form format that with mkfs.ext3 -c -I128. How do I unmount the dive?
any help would be great
Thanks
Chris

Ubuntu 9.10 is Ext4 you can't read it with MS. You can use a NTFS partition to share with both OS, I use a external HD myself.

You can also access W7 from Ubuntu and move files easily.

Sorry not sure if I put in first post that I format /home as ext3 then install ext2if in windows to enable it to read and write ext3

On the Ext2IFS website FAQ, under the ext3 section, it says this:
"The Ext2 file system driver of the Ext2 IFS software will refuse mounting an Ext3 file system which contains data in its journal, just like older Linux kernels which have no Ext3 support. In this way data loss and damaging the file system is avoided when the journal is subsequently replayed. So you can access only those Ext3 volumes with the Ext2 IFS software which have been cleanly dismounted beforehand. "

Obviously, your Ubuntu partition has data in the journal. You have to dismount the volume before booting Windows.

Can you tell me how to cleanly dismount the volume
