what is an sda and how do I use it's space?
I made a small sda1 partition at the beginning of my hard drive in ext2 or 3 file format to place a ping backup of my windows drive. however, i can't seem to get into sda1 to store files and my install of ubuntu seems to have put files within it.... where can I get good understanding of the file/partition systems/structures. I'm planning on eventually switching to linux solely, if I can understand it more fully.
thanks for any help,
