title: Is there a tools to see how many writes an SD card has left?
body: <p>Is there tool capable of reading meta-information from an SD Card?
  Similar to what smartctl can do for normal hard drives?</p>
  
  <p>Story:
  I have built a router for a public network, and it store all its logging information and database onto an SD card. After a year, the SD card stopped working.
  I assume it did too many writes and passed away. Now I want to replace it and build a tool that will alert me before the card dies,....</p>
