Browse our FAQs about USB Flash Drive

General knowledge

When I plug in my Integral USB Flash Drive a message states that more power is needed. Why?
  • Each USB device (such as an Integral USB Flash Drive) that you plug into a PC or Mac draws power from the system. Each device draws the power consumption that it needs to operate. Each device is slightly different in what power it draws.
  • If you use a USB hub so that you can plug in many USB devices, then this will also be quite a drain on the power from the PC/Mac. The more USB devices you have, the more power you are drawing from the PC/Mac and there will come a cut off point where the PC/Mac cannot output enough power to support all the devices.
  • We suggest that if you are connecting a USB hub to attach more USB devices to your PC/Mac then you will need to independently power the USB hub (e.g. plug into mains power) so that it will have sufficient power for all USB devices attached to it.
  • You can remove other power hungry USB devices, so that you can use the USB drive.
How do I copy my files and documents to the USB Flash Drive?

Copying files could be done in many ways. First insert your USB into the PC after it has booted. The USB should be recognised by the PC and assigned a drive letter. Look under “My Computer” to see the letter assigned.

Using a Windows PC, some of the easiest ways to copy data to your Integral USB Flash Drive are:-

A. Select the files that you want to copy.
B. On the toolbar click on Edit =>Copy. This copies the location to the system memory on the PC.
C. Open the drive for the USB Flash Drive. On the toolbar click on Edit => Paste. This copies   the files from the PC memory to the USB Flash Drive.

Or

A. Select the files that you want to copy.
B. Right-click on one of the files (you will see that the rest of the files stay highlighted) and click on Copy. This copies the location to the system memory on the PC.
C. Open the drive for the USB Flash Drive. Right-click in a white empty space on the drive and click on Paste. This copies the files from the system memory to the USB Flash Drive.

Or

A. Select the files that you want to copy.
B. Press Ctrl and C (this is the Windows shortcut for copy) on the keyboard. This copies the location to the system memory on the PC.
C. Open the drive for the USB Flash Drive. Click in a white empty space on the drive and press Ctrl and V (this is the Windows shortcut for paste) on the keyboard. This then copies the files from the PC memory to the USB Flash Drive.

Can I plug my Integral USB Flash Drive into a eSATA Combo Port?

Yes you can, the Integral Flash Drive will function as if it were utilizing a USB 2.0 port.

What would happen if I unplug my USB Flash Drive while data is being written to it?

Your data on the USB Flash Drive can become corrupted or lost and the file system of the Flash Drive may become corrupted as well. It is always recommended to use the “Safely Remove Hardware/USB” option when using your Integral Flash Drive on a PC or Mac.

How long will data stay valid for on a USB drive ?

Memory cards and USB drives are NOT designed for long term storage. You should always backup your data on to another device. The data will normally stay valid for a period of up to 10 years if stored under normal conditions. The data cells inside carry a charge which can dissipate over time. The data can be refreshed; copy all data off card and then format the card or USB drive and then restore all data to extend the data for another 10 years.

Why does my USB drive show less capacity than stated on my PC or MAC

The difference is due to way that most storage manufacturers and PC manufacturers define a scale. There are two systems decimal and binary.

Storage devices use a decimal system and PCs use the binary system -this leads to some discrepancy between actual capacity and reported capacity by a PC. The difference can be between about 2% – 9% depending on the capacity of the drive.

Some additional capacity is taken up by features required by the operating system e.g. FAT tables and the flash drive controller e.g. spare blocks for wear levelling.

Decimal (Dec) bytes Binary (Bin) bytes Ratio (Dec/Bin) % Diff
Kilobyte 103                               1,000 210                                       1,024 0.9765625 2%
Megabyte 106                       1,000,000 220                                1,048,576 0.953674316 5%

Troubleshooting

Why can’t I copy large files to my USB flash drive

Your USB may be set to the Fat32 file system. USBs set to this have a 4GB limit on file size. For larger than 4GB files format your USB using exFAT or NTFS file format.

Why doesn’t my PC recognise my iPhone photos?

This is most likely because your PC does not recognise the HEIC format. In 2017, Apple began using the High Efficiency Image Container (HEIC) format in iOS 11 and macOS High Sierra. This format allows for smaller file sizes than JPG or PNG.

If you would prefer that your iPhone camera saves images in JPG format, you can go to Settings/Camera/Formats and set the ‘Most Compatible’ option. Your camera will now save all images a JPGs – but be aware that your images will now be larger in filesize.

Windows 10 supports HEIC files, however earlier versions of Windows may not. If you wish to view your HEIC photos on Windows and your PC does not recognise them, we recommend converting them to JPG using this handy online tool: https://heictojpg.com/

Why doesn’t my PC recognise my iPad photos?

When I plug in my Integral USB Flash Drive into a USB port, it is not recognised, why?

The Integral Flexi, 360, Secure360, MicroLite and UltraLite USB Flash Drives only have pin contacts on one side of the USB connector.

When you plug the device into the USB sockets of you PC make sure that the contacts are matched up so that the device is plugged in the correct way. If the Integral USB is not recognised, turn it 180º, so it is the other way around in the socket.

I have corrupted data on my USB Flash Drive and the PC will not allow me to delete these files. What can I do?

This can occur if the file allocation table (FAT) has become corrupt in some way (e.g. loss of power etc).

The drive can be formatted to remove the problem.

Formatting the drive can erase all data. If you have any data on there it is advisable to retrieve it first on your computer. You may need to use file recovery software before formatting.

When I plug in my USB Flash Drive, I get the message “hi-speed device plugged into non-high speed device”. What does it mean?

This means that your PC or laptop has a USB 1.1 port and will not function at the high speed offered by USB 2.0 devices.

This is not a error message and your Integral USB Flash Drive is backwards compatible to work at the slower speeds of USB 1.1. To get the full functionality of the USB 2.0 Flash Drive you will need a PC or laptop with USB 2.0 sockets.

The chart below represents the three tiers of the USB Series:
