**Hack/workaround alert** I had a similar problem with my computer.
I simply forced UDMA Mode 4 and ATAPI-5 in the BIOS instead of "Auto". This fixed my problem and may fix yours as linux then is forced to use that speed irregardless of the 80-wire cable being detected. -- Wrong UDMA mode due to error in 40/80 wire cable detection https://bugs.launchpad.net/bugs/195221 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
