Is it OK to partition a Time Machine Hard Drive? I want to avoid the drive getting full, as this reduces its speed. So I would like to have a separate partition wich would garantee that the hdd doesnt gets full. And I may use the partition for other purpuses. BTW, the drive is already 5 times what I need for backup or external storage, and would be a firewire drive Second question, since we are at it, is it ok to keep files in your time machine hdd, along the backups folder?
