Is there a way to make ext-filesystems use less space for themselves in Linux?
I have a bunch of external and internal HDDs that I use on a Linux system. I only have Linux systems, so using a Linux file-system would only make sense, right? However I'm currently using NTFS everywhere, because it gives me the most usable space…

Is it safe to use a HDD while rsync is running?
I plan to backup my large HDDs by rsync, and anticipate that it takes a few days. Is it safe to use the original HDD (adding files) while rsync is working? Or it is better to leave the HDDs untouched until the rsync is finished?

How do I format a drive as EXT4 on Windows 7?
I'm trying to create an ext4 file system on an external drive. The partition manager I usually use, EASEUS Partition Master, doesn't support ext4. What are some free alternatives?

Major practical differences between ext3 and ext4 - if any?
Assuming there's no need to worry about compatibility with older systems, I expect it's always better to use the latest stabile linux file system, which currently seems to be ext4.
However it seems ext4 isn't much of a change. Wikipedia ext4 article…
