[ale] dd vs clonezilla to replace hard drive

[Jim Kinney]

Or do the best method and do a fresh install of your fav distro and use the
old disk as your data backup and copy over your home for.

Assuming your distro has a package manager, just export a list of installed
packages to make sure you get them all in the new install.

Sometimes a "drive migration" makes sense in a business setting. Other than
just for practice, it's basically a time waster for personal stuff and
especially if the new drive is much larger that the old drive.
