Comment 1 for bug 1342146

1) I not see any problems with drives sizes on my 64-bit computers with TB size devices. But I using unsigned long instead of unsigned long long. Now I checked this, and now I see, ulong isn't enough on 32-bit operating system.
I fix this problem soon.

2) Maybe the converting isn't possible because previous size problems.
(But otherwise, there is a need to double the size of free space.)

3) I testing this soon...
