It's not corruption. udev dynamically generates device nodes when it starts up, and they are created too slowly for other maintainer scripts to rely on anything but the root file system to be there at any given moment. I am at some point in the future going to revisit this whole issue, and provide proper support for udev systems, but as I don't use udev, it will require some research and thought first (as well as probably a couple of false starts). > If you can suggest anything I can do to help track down the issue, > happy to do so. No, there's nothing more for you to do, I'm afraid (unless you want to write the patches to provide proper udev integration :). Your approach sounds like it's working for you, and I'm glad for that. The reason the suggestion was made to run it at S29 is that I am worried that changing drive access modes could lead to disk corruption if done while the drive is mounted and the data is in use, and S29 is about as late as hdparm can run before that happens. In your case, though, it's a CD/DVD drive, so this is (virtually) impossible. -- ----------------------------------------------------------------- | ,''`.
