There is an issue with linking from the article linker (when you click on Check for Full Text) to article links for journals in ScienceDirect. If you click on an article link, this message displays when you pass through to ScienceDirect:
Sorry, your request can not be processed due to a system problem. Contact the Help Desk if the problem persists. [SD-009]
Our provider will be putting a fix in place on Feb. 21st.
For the links that result in the SD-009 error, the simplest workaround is to use the Journal link instead and then navigate to the volume/issue. While not ideal, you can still get to the full text.
