I have total of 5 WD My Book 1230 USB 3.0 external HDDs, and 3 of them don't display S.M.A.R.T data through Stablebit Scanner, even after turning on the "UnsafeDirectIo" on Scanner.Service.exe.config file and restarting Scanner service. Heck, I even rebooted the machine after turning on this entry just to make sure it was not user error.
To make sure that S.M.A.R.T data was available, I used DirectIOTest utility and it correctly displays S.M.A.R.T attributes after turning on the "Unsafe Direct I/O" option. The screen prints are as below as well as the screen print from Scanner not displaying the temperature data which is one of the attributes.
Just to make sure that S.M.A.R.T data was available to other utilities, I also accessed those attributes using CrystalDiskInfo and indeed they were. Screen Print attached in subsequent posts due to image upload size limit.
Please suggest how to fix the issue.
BTW, please ignore drives M: and L: on the Scanner screen print since it seems to be a issue with a particular multi disk USB enclosure and even DirectIOTest or CrystalDiskInfo cannot pull the S.M.A.R.T info for those 2 drives.
