Can disk imaging software be used to perform a Linux installation? When you use disk imaging software to write a Linux ISO image onto a USB flash drive, the filesystem existing on the flash drive is maintained. To perform a Linux installation over a network, you can connect to a server with the appropriate installation files via FTP.

Is ext3 the traditional filesystem used on Linux? The majority of modern Linux distributions default to the ext4 filesystem, just as previous Linux distributions defaulted to ext3, ext2, and—if you go back far enough—ext.

How much space does ext4 use?

It is the number of inodes x their size. On ext4 by default, expect something like 256 bytes per inode and for 400 GB, I am guessing mkfs. ext4 will do ~ 25-30 mill perhaps. Use dumpe2fs -h to see the actually number.
