database's on a separate partition

Hello,

I'm running cygwin 1.3.2 and postgresql 7.3.1 on Windows XP. I
wanted to initialize postgres so the databases will be stored on a
separate partition from where cygwin and postgresql are installed.
e.g.
cygwin and postgresql are on c:
if I run :
initidb -D /cygdrive/k:/postgresql/data
where c: and k: are different partitions on the same disk.

Has anyone run into problems doing something like this, or is it not
recomended? I've searched the archives and not found anything that
says not to.

Thanks in Advance,
Jennifer
