Hello Hilario; could you provide some information about which kernel or version of Ubuntu you have upgraded from?
IDE disks now appear under the SCSI layer (just as USB and Firewire disks do aswell); as such the hard-disk is now accessed as '/dev/sdX' instead of '/dev/hdY'. During an upgrade, one of the methods that is used to ensuring smooth transfer from the old method of referring disks, to the new method is by referring to the disk using a unique UUID identifier. The upgrade process should have taken care of converting these; have you done a normal upgrade, or just installed the 'linux-image' package? Entries within a new '/etc/fstab' will probably look something like: UUID=b1d95d5f-8bd6-3e7a-af2e-a8f3624ccfaf / ext3 defaults,errors =remount-ro 0 1 ** Changed in: linux-source-2.6.20 (Ubuntu) Importance: Undecided => Medium Status: Unconfirmed => Needs Info ** Summary changed: - New kernel 2.6.20-12-generic fails to mount reiserfs partitions + hda -> sda transition not handled during upgrade ** Changed in: linux-source-2.6.20 (Ubuntu) Sourcepackagename: linux-source-2.6.20 => udev -- hda -> sda transition not handled during upgrade https://launchpad.net/bugs/93655 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
