Speaking of USB devices that are not always in use, what are we going
to do to make using mountable removable media easy? I am referring to
the differences between how Linux treats removable media and how
Windoze/Mac does. For example, when you write a file to the Castlewood
ORB drive using usb-storage, that file may not have actually been fully
written. I have seen a case when I had copied a directory tree to the
ORB drive, moved the drive to a Windoze machine and discovered that
half of the files where 4KB.
I haven't really checked, but are we handling the case where a storage
device is disconnected without the usual "sync"/"umount" cycle? Is
there a way for us to do this? I notice that folks are working an the
automount portion, but I haven't seen discussion of unmounting.
