12 years ago As the DiskUtility reports smart capability, it should work. I have 3 different disk enclosures and all of them work just fine. I don't use the smartctl command directly, instead I use SmartReporter application to monitor the statuses (select disk in prefences and "Check S.M.A.R.T attributes" from disk right button menu). I have no problems in getting the attributes:

This driver is a great idea, still need some work.
Apple doesn't pay much attention to SMART -- as can be seen by the lack of any periodic SMART polling (with limited interface via disk utility).
I use SMART Utility to periodically poll my internal drives, and while I can issue -T verypermissive to smartctl (the command line tool underpinning SMART Utility) I can't get back any data on my USB drives using this driver except "SMART Verified". Disk utility does pick up on the SMART Verified variable as well.
I can apparently turn SMART on and off using smartctl, but I have no exposure to the rest of the disk variables or feature sets. No runtime hours, no SMART testing, etc.
Is this a limitation of the driver (which understandably isn't complete) or the enclosures I'm using?
One of my enclosures is a WD MyBook (the kind with two drives and hardware RAID). I guess it isn't surprising I don't have visibility to full SMART there since the drives are abstracted.
Second enclosure is a StarTech.com 2-drive USB3.0 dock. Each drive shows up independently.
Thoughts/comments? README wasn't very fleshed, so expectedly there are people like me who need to ask inane questions about the driver.
Would it be helpful for me to track down chipsets?
