intermittent failures.
Follow these guidelines to prevent ESD damage:

Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.
Connect the equipment end of the strap to an unfinished chassis surface.
Place a removed CompactFlash memory card on an antistatic surface or in a static shielding bag. If
the card will be returned to the factory, immediately place it in a static shielding bag.
Avoid contact between the card and clothing. The wrist strap protects the card from ESD voltages
on the body only; ESD voltages on clothing can still cause damage.
Do not remove the wrist strap until the installation is complete.
