<p>Method and apparatus which prevent a CF card (3) away from being damaged, the method including: a processing unit (1 ) is used to judge weather the CD1 signal and the CD2 signal are availability, and it the CD1 signal and the CD2 signal are both availability, the processing unit (1) controls the CF card (3) to be powered on; and after the CF card (3) is in the powered on status, the processing unit (1) controls the IDE data /control /address bus (2) to connected with the CF card connector (4), after the connection, the processing unit (1) can access the CF card (3). If the processing unit (1) stops the access to the CF card (3), then the processing unit (1) controls the IDE data /control / address bus (2) to break down the connection with the CF card connector (4). Thus, after the IDE data /control /address bus (2) has broken down the connection with the CF card connector (4), the processing unit (1) controls the CF card (3) to be powered off. All the above solutions should take place under the circumstance of the True IDE mode.</p> |
