Table 2-5Solving Media Card Reader Problems

Media card will not work in a digital camera after formatting it in Microsoft Windows XP or Microsoft Windows Vista.

Cause

Solution

 

 

By default, Windows XP and Windows Vista will format any media card with a capacity greater than 32MB with the FAT32 format. Most digital cameras use the FAT (FAT16 & FAT12) format and can not operate with a FAT32 formatted card.

Either format the media card in the digital camera or select FAT file system to format the media card in a computer with Windows XP or Windows Vista.

A write-protected or locked error occurs when attempting to write to the media card.

Cause

Solution

 

 

Media card is locked. Locking the media card is a safety feature that prevents writing to and deleting from an SD/Memory Stick/ PRO card.

If using an SD card, make sure that the lock tab located on the right of the SD card is not in the locked position. If using a Memory Stick/PRO card, make sure that the lock tab located on the bottom of the Memory Stick/PRO card is not in the locked position.

Can not write to the media card.

Cause

Solution

 

 

The media card is a read-only memory (ROM) card.

Check the manufacturer’s documentation included with your card to see if it writable. Refer to the previous section for a list of compatible cards.

Unable to access data on the media card after inserting it into a slot.

Cause

Solution

 

 

The media card is not inserted properly, is inserted in the wrong slot, or is not supported.

Ensure that the card is inserted properly with the gold contact on the correct side. The green LED will light if inserted properly.

Do not know how to remove a media card correctly.

Cause

Solution

 

 

The computer’s software is used to safely eject the card.

Open My Computer (Windows XP) or Computer (Windows Vista), right-click on the corresponding drive icon, and select Eject. Then pull the card out of the slot.

NOTE: Never remove the card when the green LED is flashing

After installing the media card reader and booting to Windows, the reader and the inserted cards are not recognized by the computer.

Cause

Solution

 

 

The operating system needs time to recognize the device if the reader was just installed into the computer and you are turning the PC on for the first time.

Wait a few seconds so that the operating system can recognize the reader and the available ports, and then recognize whatever media is inserted in the reader.
