  • Page 10: Formatting

    Formatting CAUTION NTFS is suitable for use with modern Windows computers. To divide the DriveStation into multiple partitions, consult the “Format/Maintenance Guide” on your Navigator CD. A Linux-compatible format will be required if the DriveStation will be connected to a TeraStation. Consult the TeraStation's user manual for more information.

  • Page 11: Maintenance

    Maintenance Backup Importance of Backups The process of copying data to external storage media for protecting important data stored in a hard drive is called a “backup”. Large-capacity hard drives store a large volume of data everyday. The loss of data due to an accident, human error, or unexpected event can result in significant losses for business operations.

  • Page 12: Error.check.(Scandisk)

    Error Check (ScanDisk) Windows includes a tool for finding and fixing hard drive errors. To ensure reliable operation, regular drive checks are recommended. Notes: • For more information on ScanDisk, see Windows Help. • Mac OS doesn’t include a hard drive error checking utility. To perform a drive check from a Mac, use a third-party utility.

    ■ RAID 10 Mode (Enables high-speed access and secure storage of data) Four hard drives are combined into a large virtual drive. Usable space is the total of two hard drives' capacity. Because reads are distributed over two drives, access speeds are slightly faster than an individual drive's.
  • Page 15 ■ RAID 1 Mode (Enables secure storage of data) Drives are combined into mirrored pairs. Total usable space is the capacity of two individual drives. All data is written to two drives simultaneously. If either drive in a pair fails, all data can be recovered by replacing the drive.

  • Page 16: Hard Drive

    ■ RAID 0 Mode (Enables use as a high-speed, large-capacity hard drive) This mode uses the four hard drives as a single large-capacity hard drive. Data is distributed and written to the four hard drives simultaneously for faster access. The OS recognizes this as a large single drive with a capacity equal to the sum of the four hard drives. RAID 0 does not provide a mechanism for protecting data.
  • Page 17 ■ Spanning Mode (Enables use as a large-capacity hard drive) In this mode, all four hard drives are combined into a large single drive with capacity equal to the sum of the four individual drives. Because data is saved without distributing to the drives, the data access speed is the same as that of an individual drive.
  • Page 18 ■ Normal Mode (Enables use as four hard drives) In this mode, the hard drives are used without building a RAID array. The DriveStation is recognized as four hard drives, and different data can be saved to each one. • Example of Hard Drive Configuration Configuration using HD-QL4TU3R5: Recognized as four 1 TB hard drives Data Data...
