You are right, the Hitachis support that. I thought disabled means not possible. My fault. Nevertheless I put the smartctl -x -a logs at http://evilazrael.net/bilder2/logs/smart_xa_20130202.tar.gz I am currently reading about TLER, and i am wondering why I haven't heard of that before. Looks like the lower power consumption is not the only advantage of the WDC Red Edition. Most reviews do not go so deep into detail. sdg is a new WDC Red I bought today so all drives from sdg moved one letter down. Spent the last three hours analysing why the second onboard controller does not detect the new HDD. In the end it's a Marvell, IOMMU and linux driver problem: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1005226 https://bugzilla.kernel.org/show_bug.cgi?id=42679 Marvell = PITA :( >> To be honest, I don't trust SMART much and prefer a write/read badblocks >> over SMART tests.
