6 DX-HD303513 Troubleshooting Troubleshooting I do not see the enclosure/additional drive in my system • 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. • Open the enclosure and make sure that all of the connections are securely fastened. • If you have a desktop computer, try using the USB ports on the back of the computer instead of the front USB ports. The cables connecting 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. There is a USB icon in the system tray, but I can't find the hard disk in MY COMPUTER • Make sure the hard drive has been initialized and partitioned if using a new hard drive. If you need to do this, see "Partitioning and formatting a new hard drive" on page xx. • If you have Windows 7, you may not have rights to the files and folders and may need to take Ownership of these files and folders. Go to http://support.microsoft.com/kb/2623670 for more information. The data transfer between computer and device is slow • 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 with your hard drive enclosure if you are using USB 3.0 ports. Data throughput is greatly 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. The data on my hard drive is corrupt! • 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 is likely caused by removing the enclosure while data was still being written to the hard drive, from subjecting the drive to some kind of physical trauma (even very subtle trauma), or due to a design or quality issue with the original drive manufacturer. 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. Can I boot from the enclosure? • This enclosure does not support using the enclosed disk drive as a boot device. Why can't I partition or format my drive? • Verify that you are logged into the computer with an account that has Administrator Rights. If that does not resolve the issue, contact your hard drive manufacturer or PC manufacturer for assistance. My hard drive is 2TB, are there any unique issues? • Make sure you have the latest Service Pack installed on Windows XP. With the latest Service Pack, Windows XP, Windows Vista, and Windows 7 should recognize up to a 2TB drive. Is RAID or JBOD • No supported? Why do I keep seeing 8 GB of hard drive space (no partition)? • This is most likely because this space was either not partitioned or initialized when the hard drive was formatted. Another reason is that when the hard drive has been removed improperly, a ghost drive can be created on the computer which confuses the computer into thinking there is still usable space. It is best to turn off the enclosure and reboot your system. Can I use the hard drive enclosure with a Mac and a PC at the same time? • No, the hard drive must be initialized and partitioned for one or the other. When formatted for Mac, a PC will not be able to see the partition, and vice versa.
