I have a brand new WDC WD20EARS-00MVWB0 Caviar Green, the first thing I
did was to plug it in and run smartctl -a and start running some
tests. I noticed that while this disk is in the S.M.A.R.T. database,
this odd message occured:
SMART support is: Available - device has SMART capability.
SMART support is: Enabled
Error SMART Thresholds Read failed: Input/output error
Smartctl: SMART Read Thresholds failed.
What is the cause of this, and how can I fix it?
thanks for your work on these tools, they are very useful,

These WD drives are exceptional - they have 4kB physical sector size.
But unless we know more about the problem we can't tell anything useful.
Repeat the comand that cause failure, add '-r ioctl,2' to them and send
result to us. Also, it would be nice if you mention operating system you
Unfortunately, I have no WD??EARS drive so my ability to help is limited.
