Device: ahci0, can't monitor Offline_Uncorrectable count - no Attribute 198
Device: ahci0, is SMART capable. Adding to "monitor" list.
Not sure what the above line "can't monitor Offline_Uncorrectable count - no Attribute 198" is telling me...
Being a bit "naughty" I have installed the ArcaOS kernel (14.201) and acpi (3.23.07) files in use to the eCS installations for testing to see if these ArcaOS only components have any bearing on the problem. This will take a few weeks...
I also see that I am still using the eCS version of os2ahci.add on my eCS installations rather than the ArcaOS version. However, they are both v1.32...
