Recommended method of handling CompactFlash cards

Handling CF cards correctly
Please note the following when handling the CF card:
● The CF card may only be inserted or removed when the system is de-energized.
● CF cards are not designed to be rewritten as many times as the user wishes.
With this in mind, you should avoid writing user data from the application to the CF card
cyclically. Depending on the system, a write operation from the application may trigger one
or more write operations on the CF card.
Therefore, we recommend you adopt a conservative approach in terms of the number of
writing processes. In other words, do not perform more than 100,000 write access instances
from the user program over the estimated service life of the application.
