2^32-2 = 4,294,967,294 or about 4GB. Based on Luthfi's earlier answer, I believe we have found the issue.

WingedPanther had summed it up for you. Both your free space sizes surpass the limitation of SetFilePointer (when missing lpDistanceToMoveHigh). Actually it seems that my earlier answer was based from wrong documentation. The online documentation (which url I gave you already) states that the limitation would be (2^31)-2. So, actually the limitation is 2GB-2B. Now we have the answer to what caused the failure in your code.
The solution? Make SetFilePointer to use proper lpDistanceToMoveHigh value. I don't recommend to alter TFileStream, so you better rewrite your code to directly use windows api instead of TFileStream.
