I think this doesnt have any effect (or maybe some old OS like DOS depend on it). If you use cfdisk for partitioning you can avoid that by given the space in c(ylinders). e.g. New Partition with a size of '100c'. I guess your hidden partition has something to do with Windows behaviour, because if you install Windows and create partitions during the installation process, it also creates an extra 8MB partition. Maybe gparted adopted that behaviour. But I can't tell you the reason why. Some people say it's for temp data (which I doubt) and others say it's used to store metadatas if the user decides to use flexible disks or software RAIDs.=20 I just can say that windows is running fine without it on my computer, because i decided to partition with cfdisk before running the installation.
