Same problem. (Knot 3 and beta) The bizarre thing is that it seems that gparted can't see b drives (hdb, sdb) but with more than 2 of the same kind it show others normally (in my case, from 3 hdd only hda and hdc are detected/visible).
Another point, don't know if related, fdisk sees all drives correctly but cfdisk don't. It complains of exactly the same drivers saying that partitions are overlaping... -- Hard disk not visible in gparted and Ubuntu installer in live cd https://launchpad.net/bugs/63642 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
