I think people are misunderstanding the word "simultaneous"; in a multi-boot environment each OS as unique access to the filesystem. Sure Linux can access the NTFS filesystem and make changes, but while Linux is accessing the device then Windows is not. There is no _simultaneous_ access; it's one OS or the other, not both at the same time. -- rgds Stephen
