Comment 137 for bug 550559

Same problem here after upgrade to 12.04 I think. It's on 1TB Seagate drive that I have running for 4 and a half years now in Mythbuntu setup. It's the OS drive ufortunatelly, I have another WD 2TB which is fine. Started experiencing Mythtv freezes and crashes lately so thought to do a SMARt test and found the errors. AHCI mode enbaled in BIOS for the drive pre install.

Have to check for bad cable first or maybe the power supply needs upgrade.
