Update: It works 100% in openSUSE 12.1, but spews these messages constantly:

The thing that motivated me to try it was an extreme problem with Ubuntu, where on these specific Iomega USB disks, using rsync to copy from a server to the disks would hang the system completely. With 6 disks at once, it hangs within 10 seconds. Using ionice and nice might make it take a bit longer, but not much longer. With 3 disks (with ionice and nice), it took about 3 hours to hang. So my desktop is now openSUSE.

A week ago, I copied a few disks to the server without problems. And 3 weeks ago, I copied 9 2TB disks (not Iomega) simultaneously to the server. Also yesterday I had 9 Iomega disks hooked up, but 4 of the USB ports won't recognize the disks.

This also reminds me of a year ago, where I had about 4 of these same Iomega disks hooked up to a Dell Precision (different machine), and tried to copy from disk 1 to 2, and from 3 to 4 at the same time, and then after a while, the USB bus stopped working. So I moved the USB cables to different ports, and it worked again, and failed again eventually. After I ran out of ports and not even the USB mouse worked, I rebooted. Initially I blamed the hardware... but it does the same thing on server hardware with Ubuntu. And now the previously described funny behavior (similar but not same as old behavior) with my new machine, but only with these Iomega disks.

And correction: it was natty a few days ago (11.04), but I said it was Ubuntu 10 in my last post.
