The DataLocker comes preformatted in the NTFS format due to its superior performance, support and capabilities for high capacity hard drives.

Windows Users

If you require a drive that can be used on multiple operating systems, you may need to reformat the drive in the FAT32 format. Microsoft has eliminated support for FAT32 formatting for drives over 32GB  so you must use a third-party tool for formatting.

Mac Users

Mac OS users can read files from an NTFS formatted drive, however, they cannot write files to one. Mac OS users must reformat the drive with the FAT32 format in order to read and write to the drive. The native Mac HFS format is also supported, choose this file system if you will only be using the DataLocker on a Mac system.

Linux Users

Linux users may use the DataLocker without reformatting if they have an NTFS driver installed.

Here is an excellent tutorial explaining how to install the Linux NTFS driver -http://www.howtoforge.com/ubuntu_edgy_eft_ntfs_ntfs_3g

If you can not use NTFS drives you must reformat the drive using the FAT32 format.
