Are you running out of disk space on your Mac? If you’ve been using your Mac for a while you’ve undoubtedly gathered tons of files and applications. Ranging from files that you’ve created to photos, music, software downloads, application support files and more. There are tools and utilities that can help you figure out what’s on your hard disk and delete what you don’t need anymore.
So you are trying to format a drive you know is setup for PC or Windows. You keep getting an error stating Disk Erase failed, or /dev/rdisk1s1: partition size not a multiple of 4K. Its not so much an error, but rather a common oversight.
Owning a mac is great, mostly because of the plethora of simple, and effective tools that can often be had for free. Carbon Copy Cloner is an excellent example. This essential tool allows you to make exact (bootable) clones/backups of your hard drives. Some of the key features include, block level disk to disk clones, scheduling, network based backups, bootable disks, and fast incremental backups.
