Drive Partition Separating one physical hard drive into multiple independent volumes--- Most come from the factory with a single partition on their hard drive, But keeping your data, applications, and operating system on the same partition can be risky because, if something happens to the partition's index file, your computer won't be able to boot up off that drive--and even if you boot up with a recovery disc or external drive, you won't be able to access the rest of your data. Partitioning your drive essentially tells your computer to treat portions of that drive as separate entities. If you keep your system and apps on a partition separate from your data, the data will be easier to back up. In addition, you'll be less likely to lose your data in an accident; and if you ever need to reformat and reinstall OS, you will not have to worry about restoring your data backups.
