When do you need to format a hard drive in Windows 7?
A new hard drive has to be formatted with some specific file systems before being used in Windows 7 operating system (OS). Formatting Windows 7 hard drive will erase all the data on the drive and rebuild a file system. Different OS has different default file system, and Windows default file system is NTFS, OS X NFs plus, and Linux EXT family. NTFS is read-only on OS X devices, and Windows machines cannot even read hard drives formatted HFS plus. If you want to the hard drive to be readable and writable on different OSes, you can format it as FAT32, which has the best compatibility with different systems, but it has 4 GB file size and 2 TB partition size limit. If it’s an external hard drive, you can format it with EXFAT, which doesn’t have the limits and it compatible with both Windows and OS X.
