Warning: Formatting a flash card will erase all the files on the card. Most devices (i.e. your camera) that you use the flash card with will have a format feature. Before you use this feature, make sure that this size card and type is supported by the device. Also make sure that the format the device uses is compatible with any other device you might use it with (i.e. the camera may format in FAT32 but a digital frame can only read FAT).

If you are using a card reader and a PC to format the card, open "My Computer" in XP or "Computer" in Vista and Win7 and highlight the drive that corresponds to the card. Make sure you choose the correct drive letter. Then use the right mouse button to click on the drive. Choose "Format" from the menu and click on it with your left mouse button.

If you are using a card reader and a Mac, open the "Go" menu and double-click on Utilities (If you do not see Utilities, double-click on Applications and then double-click on the Utilities folder). Double-click on the Disk Utility icon. On the Disk Utility Dialog box, click once on 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. The reader may require a firmware update. The firmware update is available at the link below. http://www.kingston.com/support/technical/downloads?product=fcr-hs219&filename=HS2_191_FW_RW01

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). Kingston does not offer data recovery services. For more information on ourwarranty policy please visit http://www.kingston.com/company/warranty.asp

1. Contact a company thatspecialises in data recovery services, such as Driver Savers at www.drivesavers.com or Ontrack at www.ontrack.com, or carry out a Googlesearch for "data recovery".
2. Go to www.download.com, search for "datarecovery" and download one of the many utilities for data recovery whichare fairly simple to use. We suggest trying one of the free versions as they work just as well as the paid versions. However for this option to work, the computer must assign a drive letter to the device. Even so it is not guaranteed to work. If it does not, option #1 would be your best bet.

Secure Digital cards including SDHC, SDXC and Micro SD cards come pre-formatted in compliance with SD Memory Card standards. Formatting with Windows, Mac or Linux is not compliant with SD Memory Card standards and may cause a performance decrease.

The solution is to eitherformat the card in a device that complies with SDA standards, such as a cameraor phone, or use the SDA format utility located here:

https://www.sdcard.org/downloads/formatter_4/

Be aware this is only compatible with the following Windows operating systems. It will not work in a Linux computer, so using a SDA compatible device is preferable.

In the options section, wesuggest you use "QUICK" as the format type and have the formatadjustment size set to "ON".

Most Kingston SD and microSD cards are designed to be used in consumer products such as handheld cameras, mobile phones, MP3 players, GPS devices etc. Commercial-grade equipment should use industrial-grade cards. Kingston cards will work in commercial-grade equipment, but they are not appropriate for this type of application.
