Flash memory cards are not being detected by the internal reader on my computer. Why?

<ol> <li>Some internal card readers do not support higher capacity cards (e.g., 64GB or 512GB). Many systems, including newer ones with built in card readers, are made to support cards up to a limited capacity. The capacity of your card may exceed this limitation and a firmware upgrade from the computer manufacturer may be necessary. Check with your computer manufacturer for hardware/software fixes.</li> <li>If you have a digital camera or an external card reader that supports the flash card in question, try connecting one of these devices to the computer.

My flash card no longer works in my device or I can no longer view files saved to the card. Can the files on the card be recovered?

If you have data on your card that is important to you, we strongly recommend that you use one of the two possible ways for data recovery (see below).

I inserted my SDHC media card into a card reader, camera or other device and the card was not recognized or I was prompted to reformat the card.

Only SDHC Host devices will support SDHC memory cards. To confirm the device supports SDHC media, please refer to your User’s Guide. The picture below is used by the SD Card Association to help illustrate compatibility. <img alt="" src="http://media.kingston.com/support/images/kfc-012611-sdhc-01.jpg" /> * SDHC Host Products can use both SD and SDHC Memory Cards. * SD Host Products can use only SD Memory Card 2GB or less.

My flash card that is above 32GB shows up as not formatted in my device after formatting it in Windows. Why?

Many devices that use flash cards may only recognize a FAT32 file system. However, the Windows format utility will automatically default the file system to exFAT for any removable storage device above 32GB. Additionally, it will not give the option to format with FAT32 file system. Therefore, due to the exFAT file system, your device may not see the file system and therefore identify the card as not formatted. The best practice is to reformat the card in the device you primarily use the card with.

I am copying files to my flash memory and get an error message stating, "The directory or file cannot be created." The total size of all files is less than the capacity of the card. Why?

FAT32 file system has a single file size limitation of 3.99GB. In order to transfer a single file to the card that is larger than 3.99GB, you will need to reformat the card using the exFAT file system. Once this is done, you can transfer larger files to the flash card. Note: Make sure the device you plan to use the card with, supports exFAT file system.

My flash card is not seen by my device or shows a card error in the device, but it works OK in another device. Why?

Depending on what the device supports, you may be running into a incompatibility related issue. To confirm, you should refer to your device’s user manual for assistance. Please see below for more details. Card Type - With various card types available, it's important to make sure you are using one that is supported by your device. For example, some card types include: SDHC, SDXC, and SDUC. Although some devices may support all three card types, older devices may only support one or two. Please check your devices user manual to confirm which card types it supports. Card Capacity - Along with card types, there is also card capacity. With card capacities ranging from less than 2GB up to 128TB and above, it is important to confirm which capacities are supported by the device in question. File System - The File System can also cause support related symptoms. With the various card capacities comes different File Systems, such as FAT, NTFS, and exFAT to name a few. Please check your devices user manual to confirm which File Systems are supported. If your card is utilizing an unsupported File System, you may be able to resolve by reformatting the card with a compatible File System.

I am being prompted for a password to access my flash card. What is the password?

Kingston does not distribute flash media with password protection. This password was either generated by a third party program or by a cell phone. To regain access, use the third party software or the Lock Code assigned to the cell phone.

Can I boot from this Kingston flash card, set it as a fixed disk or run an OS from it?

No. We do not support our flash cards as bootable devices, fixed disks or something you can run an OS from.

Warning: Formatting your flash card will erase all data files!

FORMAT ON DEVICE (i.e. Digital Camera)
Most devices that support flash cards (i.e. camera) will have a format utility. Before using this feature, make sure the flash card capacity and type is supported by the device. Also make sure the format (e.g., FAT32) options offered by the device are compatible with other device you might plan to pair the flash card with. To format the card, follow the Format instructions provided in the user's manual of the device.

FORMAT ON WINDOWS PC/NOTEBOOK
Type "This PC" in the Windows search window and press Enter. Locate and highlight the drive that corresponds with the card reader containing the flash card. Then with the right mouse button, right-click the drive and select "Format" from the pop-up menu to access the format utility.

Choose the file system that is appropriate for the card size and the device you plan to pair the flash card with. Note, 2GB and below (standard capacity) should use FAT, 4GB to 32GB (High Capacity) typically use FAT32. With capacities 64GB and above (Extended Capacity), we recommend using exFAT. Once you make this selection, click Format to complete the format process.

FORMAT ON macOS PC/NOTEBOOK
If you are using a card reader connected to a macOS system, open the "Go" menu and double-click on Utilities (If you do not see Utilities, double-click on Applications and then double-click the Utilities folder). Double-click on the Disk Utility icon. On the Disk Utility Dialog box, select the flash card's active partition. Note: There will be two listings for the card, the first one is the active partition and the second is the volume label. Click the erase tab located on the right side of the screen. Using the Volume Format drop-down, select “MS-DOS File System” from the list. Click Erase.

For commercial grade equipment we only recommend use of Kingston's industrial grade SD and microSD flash cards. Although our other flash cards may work, they are primarily designed to be used in consumer products such as hand held cameras, cell phones, MP3 players, GPS devices, etc., and thus not recommended for industrial applications.

This is common for flash storage, whether internal SSD, Flash Card, or external USB storage, and 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 (e.g., File Allocation Table) and other functions such as firmware and/or controller-specific information, and thus some of the listed capacity is not available for data storage.
