Why is the available storage capacity of my product slightly less than the advertised capacity?

This is common for flash storage, whether internal SSD or external USB storage. It is due in part to a variance in how flash memory vs spinning platter hard drive manufacturers calculate megabyte. Hard drive manufacturers calculate a megabyte (or 1,000x1,000 bytes) as 1,000KBs, whereas the binary calculation for flash-based storage is 1,024KBs. Example: For a 1TB flash-based storage device, Windows will calculate it as having a capacity of 931.32GB. (1,000,000,000,000÷1,024÷1,024÷1,024=931.32GB). Furthermore, Kingston reserves some of the listed capacity for formatting and other functions, such as firmware and/or controller-specific information, and thus some of the listed capacity is not available for data storage. <div class="clearfix"></div>

Why does my USB Flash Drive and/or USB Reader get hot/warm to the touch?

In most cases, it is normal for an external USB device to get warm or hot to the touch since the exterior shell helps cool the internal components by emitting heat into the air. Some of the factors of a USB external device getting warm or hot: <ul style="list-style-type: disc;"> <ul> <li style="padding-left: 30px;">Material: Metal flash drives and readers tend to get warmer while in use than other types of USB flash devices. This is simply because metal absorbs heat much more easily than materials like plastic do.</li> <li style="padding-left: 30px;">Environmental Temperature: If the host device or surrounding temperature is high, the drive's cooling capability decreases. USB drives often become warmer when used in hot environments or with warm devices. <ul></ul> </li> <li style="padding-left: 30px;">File Transfers: Transferring large files or a high volume of files can raise the drive's temperature. Large files take longer to transfer, requiring more energy, thus generating more heat. Quick consecutive file transfers have the same effect as transferring large files, increasing the drive's temperature. During data transfer, the drive heats up internally and releases heat through its casing.</li> </ul> </ul> Note: None of the above listed factors impact the functionality of the USB device. After the data transfer is complete, wait 30-60 seconds before removing the USB device from the host machine. This should provide enough time for the temperature of the USB device to cool.

If I forgot my password or the drive no longer accepts my password. Can the data on the drive be recovered?

By default, after the predefined max number of unsuccessful password attempts is reached, the drive will format and all data will be lost. Once the format is complete, data recovery is not possible. However, if you have not exhausted the max number of unsuccessful password attempts, you may consider contacting a professional data recovery company for assistance, such as DriveSavers Inc. Please note: Kingston does not retain master passwords for encrypted USB drives.

When you delete files from the drive while the drive is connected to a macOS system, macOS will keep a backup of the deleted files, allowing you to recover files if accidentally deleted. Because of this feature, macOS will also reserve space on the drive in the event that you do recover the deleted files. Therefore, in order to recover the available storage space back to the drive, you will need to empty the macOS Bin while the drive in question is connected to the macOS computer.

If this does not work, the device should be completely reformatted. Please follow these instructions to format your Kingston drive.

WARNING: Formatting will erase all your data so please make sure you have a copy before proceeding.

Go to Go > Applications > Utilities and Open Disk Utility.
Choose your drive from the left panel and then click Erase on the right.
Select a Volume Format. Select MS-DOS File System or exFAT if you plan to use the drive on macOS and Windows. If used only in a Mac then select Mac OS Extended as the Volume Format.
Click Erase.

This is a limitation of the FAT32 file system, which has a limit on the number of files stored on the root of the drive. To transfer more data to this unit, you will need perform one of the following.

A) Create folder(s) on the root of the drive and then transfer all data to the folder(s). Once this is done, you should be able to transfer more data to the DataTraveler.

B) Back up the data on the drive to another storage, then reformat the drive with exFAT file system. Once this is done, you should be able to transfer more data to the DataTraveler.
