Hi
does someone now if a SD card microswitch detector is integrated in the hardware of the Ethernet Shield?
I want to detect if SD card has been removed during the running cycle of a program.
thanks

Earlier versions had the following:
Although not used by most SD card libraries, A0 is connected to the SD slot's write protect (WP) pin and A1 is connected to the card detect switch. Both are pulled high by 10k resistors on the Ethernet shield.
I don't think the current version has this feature. Here is the schematic http://arduino.cc/en/uploads/Main/arduino-ethernet-shield-06-schematic.pdf

Hi
I have a The Arduino Ethernet Shield.
Is the Arduino Eternet Shield V5 the latest version or an older version. Seems better with the SD-card detector switch on board.
thanks for your reply,
f.
The newest ones don't have card detect or write protect connected.
