YDL partition invisible to MacOS?

[Chris Saunders]

Good day all,

I have YDL successfully installed to a partition on my little iBook
(thanks for the help I've received here!!).  Now, however, I need to
reclaim the partition I've installed YDL for MacOS.  The only problem
is, I can't see the partition from OSX or OS9 system disk tools, and I
don't want to completely trash the partition table (done that one
already!!).  How do I reclaim the partition for MacOS?  Don't worry,
I'll come back to YDL I promise :)

Thanks in advance.
