Thanks for posting this, got me to check on my Seagate Momentus 7200 rpm 500gb HD. Looks like I'm in pre-fail stage on a bunch of similar stats after 10 months. Further digging shows that this drive suffers from similar problems, though it doesn't appear to just be tied to Max OS X. So I'll be looking for a replacement (I can't afford not to) and be extra vigilant with my backups.

hey man, I love pastie so i thought i'd throw my 2 cents in ;)

if you have macports you can install smartmontools from ports, it'll do everything the smartd utility does. I couldn't get smartd to run reliably, but smartctl got all the same output as the smart utility. Anyway just recommending opensource over questionable shareware (which i assume uses smartmon as a basis) ;)

"Pre-fail" is the type of SMART attribute. Seeing "pre-fail" in the column does NOT mean the drive is failing. There are two types, pre-fail (denoting a value outside threshold would indicate a failing disk) and old-age (denoting a value outside threshold would indicate a very old disk). I've hit old-age many times on servers, but I've only hit pre-fail on one disk. Though SMART is a good utility to have, it won't detect all failures.

Also, I personally use SMARTReporter ( at http://www.corecode.at/smartreporter/index.html ) on my Mac. It works great, it's free under the MIT license, and it is unobtrusive.

Hope this helps.
