Troubleshooting

• Make sure the drive is functioning. A drive that
does not work in a laptop will more than likely
not work with this enclosure either. When you
connect the enclosure to the PC, you should hear
the drive spin up (it may be very faint). Contact
your hard drive manufacturer or PC
manufacturer for information on testing your
hard drive.
• The enclosure may not be receiving enough
power to spin up the hard drive. USB ports are
supposed to have a power rating of
5.25V/500mA. If the system provides less than
500mA per USB port, the enclosure may not
have enough power to spin up the hard drive
completely (although the enclosure will light up
and you will hear the drive attempting to spin
up).
• Make sure that the USB cable is connected firmly
to your enclosure and computer.
• Make sure that the USB cable is not broken or
damaged in some way.
• Open the enclosure and make sure that all of the
connections are securely fastened.
• If you have a desktop computer, try using the

front USB ports are not always properly shielded
and may not properly handle USB 3.0 speeds.
• Your PC may not be able to recognize the
partition on the hard drive because it is
damaged or not a valid format. You can initialize,
partition, and format unrecognized drives by
using the software that comes with the hard
drive or by using the Disk Manager (PC users) or
Disk Utilities (Mac Users).
Caution: Doing this will erase any existing data on
the drive. If the drive is damaged and you wish to
recover the data, continuing WILL overwrite the
existing information.
• If using a new hard drive, have you formatted
and partitioned the hard drive? If not, see
"Partitioning and formatting a new hard drive"
on page xx. If the hard drive is not formatted and
partitioned, your PC will not assign a drive letter.
• There are some computers that have difficulty
starting with a USB hard drive connected.
Unplug the hard drive, then restart your
computer. Once started, connect the hard drive.
• Do not use non-powered USB hubs because they
often are unable to provide enough power.
• Make sure the hard drive has been initialized and
partitioned if using a new hard drive. If you need

• Your system may be operating at USB 2.0 speeds
due to an incorrect driver installation of the USB
3.0 adapter card. Or you may have a system that
does not support USB 3.0. If your system
includes a PCIe slot, you can achieve SuperSpeed
USB transfer rates by installing a USB 3.0 PCIe
adapter card.
• Make sure the enclosure is connected to a USB
3.0 or 2.0 port. Transfer speeds are optimal/best

USB 3.0 ports. Data throughput is greatly
and device is slow affected by the type and location of data on the
disk. A few very large files will copy much faster
than many small files since the larger files are
more likely to be arranged sequentially on the
disk.
• Magnetic Hard Disk Drives operate at speeds
slower than the USB 3.0's maximum data transfer
rate. If using an HDD, your transfer speeds will be
faster on USB 3.0 than on USB 2.0, but will still be
limited by the phyiscal disk's throughput.
• Connecting your hard drive to the enclosure is
just like connecting a hard drive to the inside of
your computer. The enclosure itself will not
corrupt your data. If data has become corrupt, it

drive is corrupt! Caution: Never remove the enclosure while data is
being written to the hard drive! Doing so may cause
the hard drive to become corrupt. Make sure all
applications being run off the disk and all files in use
are no longer in use before removing the unit. For
PCs, use the Safely Remove Hardware icon to eject
the drive before disconnecting. For Mac, drag the
hard drive to the trash before disconnecting. Never
operate the disk and enclosure in a partially
assembled state.
