Comment (by davidsaunders):
I am not familiar enough with the API that DriveSetup is using to figure
out were the problem is.
Considering that DriveSetup uses the Operating System API to write out an
FS (as far as I can tell), I do not see how it is possible for it to be
more than 4K in size (256 Bytes max for partition editing code + 1024
Bytes max for strings and partition types + 2048 Bytes for the windowed
user interface [All estimates from experience on other projects rounded up
to nearest power of 2 to give benefit of the doubt]). A system call should
never take more than 64 Bytes application code, unless it takes a huge
number of parameters (greater than 8).
