Why is the actual storage capacity of the product slightly less than the volume written on the product specification?
Hard drive manufacturers calculate a megabyte (or 1,000x1,000 bytes) as 1,000KBs, when in fact the correct calculation is 1,024KBs. So, for a 8GB storage device, Windows will calculate it as having a capacity around 7.2GB.
Why do I get a "The disk is write-protected" message when I transfer files to my SD card?
There is a Lock switch on the left side of the SD card. Make sure the Lock switch is slid up (unlock position). You will not be able to modify or delete the contents on the memory card if it is locked.
SOLUTION 2 - Toggle the lock switch.
If the lock switch is loose and moves easily It is likely the switch is sliding to the locked position as the card is placed in your host device. In this case the card will need to be replaced.
What should I do if I cannot delete or format my SD/SDHC card due to write protection?
Please make sure that the write protection switch is on the correct position. If the problem still exists, please kindly take the product with the receipt back to the original retailer and ask for a repair or replacement service.
Why can't my digital camera use a higher capacity flash card?
Please contact the manufacturer of your digital camera to verify its maximum supported capacity.
How come the files in my memory card are corrupted?
Taking pictures or recording with a camera that is running low on batteries, or has an unstable power supply.

Also, please remember to format your memory card in the camera before using.

My card reader is not being detected, how do I troubleshoot?
addling card readers support Windows Vista, Windows XP SP2 and Windows 2000 SP4, Windows 7.
NOTE: No additional drivers need to be downloaded for the card readers as they are native to the above mentioned supported operating systems.
NOTE: It is recommended that you plug your card reader to the back USB port on your PC to ensure that there is enough power from the USB port for the card reader to be detected properly.
1. Right-click My Computer.
2. Select Manage.
3. On the left pane, click Device Manager.
NOTE: The card reader will appear in two places: Disk Drives and Universal Serial Bus controls as USB Mass Storage. If there is a yellow exclamation point (!) or question mark (?) next to the device, try to refresh the drivers.
1. Right-click the entry with the error mark, select Uninstall.
2. On the top menu, click Action, and then click Scan for hardware changes.
1. Double-click My Computer.
2. Look for the card reader under Devices with removable storage.
A yellow exclamation point (!) under Device Manager usually means that the device is not receiving enough power. If the reader is not receiving ample amount of power from the USB port, it may not function properly.
NOTE: The SDDR-89, SDDR-189, SDDR-289 reader should show 4 drive letters under My Computer.
