An external hard drive has three main purposes: to expand your computer’s storage capacity, to back up your data, and to share data between computers. It’s also easy to use. Most of the time, you just need to plug it into the computer and use it as an internal hard drive. Desktop external hard drives are based on the 3.5-inch internal hard drives, and laptop (or portable) external hard drives are based on the 2.5-inch internal hard drives.

PC users may need to format your hard disk sometimes when you want to convert the FAT File System to NTFS File System. Through formatting the drive, you can change the File System. You may just right click the drive and choose “Format”, and then selected “Quick Format”, but after clicking “OK”, you may be aware that another drive was formatted. The only solution to access your important files on the mis-formatted drive is to do format recovery.

people may forget to back up the important data and you may remind of it just after format. If so, do not hesitate to get reliable data recovery software to recover your files after format. Once your formatted partition is overwritten by new content, you will lose the chance to restore your important files and will never get them back. Aidfile Data Recovery , specializing in data recovery from various data loss conditions, can recover lost files after format safely and efficiently.

Disk formatting is the process of preparing a hard disk drive or flexible disk medium for data storage. In some cases, the formatting operation may also create one or more new file systems. The formatting process that performs basic medium preparation is often referred to as “low-level formatting.” The term “high level formatting” most often refers to the process of generating a new file system. In certain operation systems (e.g., Microsoft Windows), the two processes[clarification needed] are combined and the term “format” is understood to mean an operation in which a new disk medium is fully prepared to store files. Illustrated to the right are the prompts and diagnostics printed by MS-DOS’s FORMAT.COM utility as a hard drive is being formatted.
