Strange combination; the structure looks like Quenya, but it can't be (because of the 'd'); the combination -'dra' and the and of a word left as an open syllable is rather strange for an elvish language; so is '-adr-';
The single elements could be borrowed from Tolkien's elvish languages though, 'sad' is a typically sindarin syllable - alone it's meaning something like 'place', but the second syllable in the word 'sador' is probably (im not sure about the etymology) a later-added, unstressed filling one, so it could be reduced to sadr- again (meaning 'trustworthy person');
'rien' or even 'ien(d)' doesnt look like sindarin though, it sounds a little like a random female ending for a name - so maybe 'sadrien' could make sense, but 'sadriendra'? no idea the structure somewhat resembles Isdira, a non-Tolkien-but-Tolkien-copied elvish language - what translator did you get it from?

Ok, the names there aren't too precisely respecting the Ardean phonetic codices they're beautiful, but not always describing the people they're belonging to too well..
For example I get "Uneraswen" as a human name - the ending '-wen' is clearly of grey-elven origin, but the rest is not really typical for any language; could be some human dialect, though the 'sw'-sound sounds rather strange and is normally typical for real germanic languages.
The elf name is "Eowadia" - definitely not fitting in any phonetic categories of the common elvish languages, but instead sounding like a made-up anglosaxon name ('éo(h)' for example, like in several common rohirric names, means 'horse').
For Dwarvish, in contrary, I get 'Gwaelyan' - containing several typically grey-elven elements, only the '-lya-' in the end is a lil strange.

Everyone does know that the links given only give Grelvish names, right? If you want a literal translation of your name, the Quenya Lapseparma (elvish.org/elm/names.html) is a good site.
