I get a nearly identical problem on my MO drive. and I'm fairly certain the
media is good. the drive is new and works fine on other volumes.
additionaly, if I try to write to any file in a directory the contents of
that directory seems to disappear until reboot, yet nothing can actually be
written to a file. the "close" operation is undefined, but BSD may think
it's seeing an optical drive that's read only. and running fsck obviously
doesn't fix anything.
