Featured Questions

Flash memory cards are not being detected by the internal reader on my computer. Why?
  1. Some systems do not supporthigher capacity cards (e.g., 1GB or 2GB). 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.
  2. If you have a digitalcamera or an external card reader that you know supports 2GB cards, tryconnecting one of these devices to the computer. If you can successfullyview the card via the external device, the problem may exist with your built inreader.
  3. If you have an SDHC (SecureDigital High Capacity) card, it is possible that the internal card reader onyour computer does not support this technology. Although SDHC cards look identical to standard SD (Secure Digital) cards, SDHC cards are not backwards compatible with standard SD format host devices. Standard SD devices cannot read the format of SDHC cards. To ensure compatibility, look for the SDHC logo on cards and host devices (cameras, camcorders, etc.). If your device does not support SDHC cards, we suggest that you contact your place of purchase to exchange it for a standard SD card. Note: Standard SD cards are not available in capacities larger than 2GB.
  4. If you have Windows XP,Microsoft has acknowledged a Windows XP limitation with SDHC cards. Click the following link for the hotfix: http://support.microsoft.com/kb/934428.

More Questions

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?

This is a limitation of the FAT file system. In order to transfer more data to this card, you will need to remove the current data on the card and create folders on the card to copy files to. Once this is done, you should be able to transfer more data to the card. You can also reformat the card using the FAT32 file system. However, make sure the device you use the card with supports this file system.

FAQ: KFC-012611-GEN-03
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?

There is a incompatibility between the card and the device. This can be due to the device not supporting the capacity of the card or the card using a newer technology than the device is able to use. In some cases, there are updates to the device that allow it to read newer or larger cards. Please check with the device manufacturer or on our website to see what cards are supported with your device.

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 mobile phone. To regain access, use the third party software or the Lock Code assigned to the mobile phone.

FAQ: KFC-012611-GEN-06
What does the X rating for flash memory mean?

The X rating is a measurement of the performance of the card. It is determined by dividing the write speed of the card by 150KB/s*. To put it another way, you can determine the write speed of a card by multiplying its X rating by 150KB/s. For example:

50X = 50(multiplier) x150KB/sec = 7.5 MB/sec

* 1 KB = 1,000 Bytes; 1 MB= 1 million Bytes.

FAQ: KFC-011911-GEN-01
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). 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.
