I think I figured it out:
Select Top 1000000 tblcomputers.Computer, tblntlogevent.Eventcode, tblntlogevent.Logfile, tblntlogevent.Message, tblntlogevent.Sourcename, tblcomputers.Description, tblntlogevent.TimeGenerated From tblntlogevent Inner Join tblcomputers On tblcomputers.Computername = tblntlogevent.Computername Where tblntlogevent.Eventcode = 7 And tblntlogevent.Sourcename = 'disk' And DateDiff(d, tblntlogevent.TimeGenerated, Current_TimeStamp) <= 2
