Problems mounting linux partition as rw


Ok, I have a dual boot netbook with Ubuntu and Windows 7 on it. I want to access and change some information on my Ubuntu partition from another distro of linux.

I am running tinycore off of a flash drive and trying to mount my linux partition with write permission.

When I try to do
mount -o rw /dev/sda3 I get the error "Invalid Argument"

It will however let me mount it as read only.

I have also tried to boot in single user mode so that I can change a file, but again it only boots in read-only.

Any thoughts?

the target mount point is missing:
Code:
mount -o rw /dev/sda3 /<some_path>

don't use the -o rw switch - try to adjust the permissions with chmod (with root, or in Ubuntu with the regular user)

Did you run fsck on it? It could be that the filesystem is dirty (improperly unmounted). Also is your partition formatted to ext4? some mini-distros lack ext4 support and tend to choke in funny ways when trying to mount an ext4 partition.

AHH it was the fsck, it did not unmount properly. I fixed the errors and was able to mount just fine. Thanks all. I've been working on that for a bit now.
