Frequently asked questions

Q : Do I need USB drivers for Windows?
A: No, they are already available with your operating system.

Q : Can I boot my system from the drive? A: No, because Windows does not support booting from external hard drives.

Q: Why doesn’t the drive need a fan?
A: The drives are designed to have optimal heat dissipation, and therefore no fan is required. This results in a near
silent operation.

Q: Why is the capacity of my drive (as shown in Windows) lower than the drives actual stated capacity?
A: This difference can be explained because of the different methods of calculating the capacity. Hard drive manufacturers calculate on the decimal system, while the operating system calculates in the binary system.

Example decimal:
1TB = 1,000GB
1GB = 1,000MB = 1,000,000KB = 1,000,000,000 bytes

Example binary:
1GB = 1,024MB = 1,048,576KB = 1,073,741,824 bytes
As a result, a 1TB (decimal) hard disk appears in Windows to have just 931GB (binary).

Q: Can I use my drive to copy an operating system from one computer to another?\
A: No, you must follow the operating system supplier instructions for installation. A simple copy does not work.


My computer does not recognize the disk drive at all.

  • Make sure all of your connections are secure.
  • If your drive is connected via a USB hub, make sure that it has its own power supply.
  • If using an add-on card, make sure it is working properly and update the software/firmware.

Is it dangerous if the drive feels warm whilst in operation?
A: This is normal, and therefore not dangerous.

The drive gives me a “Device cannot start .”
: Two possible reasons. It is either a power problem and you should check the connections, or the drive has a malfunction and requires service.

I cannot see my drive in “My Computer/This PC”, but it does appear in the Device 
A: Follow these instructions:

  1. Right-click “My Computer/This PC”.
  2. Select “Manage” in the pop-up menu.
  3. Select “Disk Management”.
    You should see a list of available storage devices.
  4. Check whether your drive is listed.
  5. Right-click the right hand box and select “Delete Partition” in the pop-up menu.
  6. Right-click the box and select “Create New Partition” in the pop-up menu.
  7.  Then select “Primary Partition” in the partition wizard window. Click next.
  8. A drive letter will be displayed, which you can change. Click next.
    NOTE When you format the drive all the data on your drive will be deleted.
  9. Confirm to format the drive.

As I try to format the drive, I receive the message “Could not complete format”.
A: This can be caused by formatting the drive with FAT file system. Try “NTFS” file system. This should solve the problem.
