General Questions
Q: I bought a 500GB drive, but my computer is showing
465GB. Where is the missing capacity?
A: Hard drive manufacturers market drives in terms of decimal
(base 10) capacity. In decimal notation, one megabyte (MB) is
equal to 1,000,000 bytes, and one Gigabyte (GB) is equal to
1,000,000,000 bytes. Many operating systems use the binary
(base 2) numbering system to describe disk capacity, where
one megabyte is equal to 1,048,576 bytes, and one gigabyte is
equal to 1,073,741,824 bytes. Simply put, decimal and binary
translates to the same amount of storage capacity.
Q: Is my external hard drive bootable?
A: Yes! As long as your host hardware and operating system
support booting from eSATA, USB (PCs) or FireWire (Mac).
Refer to your computer’s documentation for more information
Q: My drive was working fine yesterday but now its gone!
A: The disk may have been shut down without being dismounted,
or may have failed. If you do not hear and feel the drive spin up
when you connect the power, the drive will need to be replaced.
If you verify that the computer input and the drive data cable are
working, you may be able to repair or recover the data with your
computer’s disk repair utility or a third party utility. If your disk
repair utility cannot repair or see the disk, the drive has failed
and will need to be replaced. If data recovery is desired, please
contact an established professional data recovery firm. For a
checklist of what qualities you might seek, see www.drivesavers.

Q: Can I leave my GreenDrive Quad on all the time, or should
I turn it off when not in use?
A: The GreenDrive Quad is meant to be left on, but does not add
any limitations on being turned off. Drive reliability is definitely
affected by repeated power cycles, and the GreenDrive Quad
cannot alleviate this. In addition, Fantom Drives recommends that
the drive’s power supply is connected through a UPS or surge
protector; In case of a power surge or brown/black out the hard
drive’s sensitive electrical components will not be damaged.
Formatting Your Drive
THIS DRIVE HAS BEEN PREFORMATTED FROM THE FACTORY USING
THE HFS+ FILE SYSTEM. HFS Plus is a file system developed by Apple
Inc. as the primary file system used on Macintosh computers.
If this drive is to be used with Macintosh computers exclusively,
you may leave the file system as is.
HFS+ has limited compatibility with Microsoft(R) Windows hosts. If
this drive is to be used with non Macintosh computers, reformatting
the disk drive to a native file system is recommended, but HFS
volumes are accessible via third party software such as MacDrive
from MediaFour (www.mediafour.com).
ATTENTION! Your Fantom Drives device may be larger than
2TB. Large LUNS (>2TB) must be supported by the host bus
adapter and the host operating system to be usable. Windows
2003 and newer, Mac OS X 10.4.8 and newer, and Linux
distributions with appropriate kernels all support large LUNS.
Windows XP and prior cannot address large LUNS.
Formatting a hard drive erases all data contained on it. Please
be sure to create a copy of the files you wish to keep to another
location before reformatting.
