What are your best computer tips?

Oh, and my computer tip - always encrypt your pr0n.

Why?

Use Clonezilla whenever you need to duplicate (in whatever fashion) partitions or whole disks.

It works with all of the file systems & it is easy to use.

dd failed me & Clonezilla didn't.

Across multiple partitions that included fat32, HFS+, ext3, JFS file system. Which is a pretty good test imho.

After the drive clone, OS X, booted, & so did Arch & all data partitions were accessible & had data integrity.

Clonezilla did a perfect job, which is exactly what was required.

[Edit:] Even though Clonezilla uses dd itself for certain file systems.
