I didn't get the chance to test it there, but I installed 2.4.4 this morning. Alas, I receive exactly the same errors with 2.4.4 as I did previously with 2.4.3. One thing that did differ, though, shortly after I sent this first email, magically the drive started working properly. I was able to mount disks perfectly. However, I had to reboot for some reason or another, and the problem came back and has stayed with me ever since. As far as I know I didn't do anything to make it work when it did, it just "started working", which isn't an answer I like, but that's all I can say.... :-) Tim On Wed, Apr 11, 2001 at 10:53:57PM -0400, Tim Meushaw wrote: > Hi there.
