I manually keep an eye on this 40gig drive as smartd would likely moan far too much. Vendor Specific SMART Attributes with Thresholds:
I say this with an HDD here like this:Ĭode: Select all SMART Attributes Data Structure revision number: 16 It might be worth looking at smartd and have the drive test itself periodically, and send a notification if the drive looks to be failing. As it happened the drive did die anyway, some cheap Samsung 1.5T IIRC from a computer fair. In the end I set up a cron'd script to just tickle the drive frequently enough that it wouldn't spin down. I had a USB HDD for a while and I couldn't get it to stay powered on.
If an HDD is being run flat-out most of the time and is insulated then power control might extend its life, but just dealing with the heat is probably a better aim. I back up my "research" with the anecdote lots of people will have heard about hard drives, "it was OK last time I used it".Ī spun-down hard drive might save battery life, if applicable (ie laptops, and not most Pis), but to keep a drive going for years I think keeping them powered-up and spinning is best. IME keeping hard drives on gives them life, it is the power cycling that finishes them off.
