Error is now explicitly set to zero. 2) SMART The smart values that were returned were invalid and tools like skdump would not recognize that the smart data was actually valid and would dump weird output. The data has been fixed up and raw value support was added. Tools like skdump and palimpsest work as expected. v5 changes: rebase v4 changes: incorporate changes from Ryan Harper v3 changes: don't reformat code I didn't change v2 changes: use single structure instead of one for thresholds and one for data.
