Scott, when using the old (non-sata based) ata drivers, you see the disks as hd*. When using the sata-based ata drivers, you see them as sd*.
This particular bugreport was opened for the scenario when the new sata- based drivers were used for disks with a host-protected area (HPA) present. In these cases you could see messages like this: [ 663.015850] attempt to access beyond end of device [ 663.015854] sdc: rw=0, want=234484734, limit=66055248 -- pata driver in libata not mounting /home https://launchpad.net/bugs/82314 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
