[Enhancement] List's should be returning an IEnumerable, so that exceptions can be handled by the caller

[Smurf-IV]

Because of Defect #1 then I cannot get even 1 drives information, therefore if the following was an IEnumerable return:

Then I could handle the exception and still get more drive INfo's, Also being an IEnumerable means that slower drives (Or ones that may be put to sleep) have a chance to spin up and then return the SMART info etc.

Note: the existing API's can still exist by calling the new IEnumerable API's with .ToList() so that only 1 code route exists.
