While on a recent trip, logcheck started telling me about a problem:

Mar 19 07:26:55 bast smartd[1573]: Device: /dev/ad0, Failed SMART usage Attribute: 9 Power_On_Hours.

Looking at the full output:

On line 59, you’ll see that this drive has been in use for 7.4 years. Other than that, it seems to be OK. This link seems to indicate there is nothing to worry about.

This system dates from at least October 2005. It is one of the systems I was planning to replace with recent purchases.
