This project is a fork of the MMC utils project at http://git.kernel.org/cgit/linux/kernel/git/cjb/mmc-utils.git/. Modifcations are made to the original project to initially add support for reading SMART data from Delkin micro SD cards. The addition of SMART to the micro SD cards is a big benefit as you can monitor key parameters such as percentage life remaining etc.
The spec. for the Delkin SD cards with SMART support can be downloaded from their website at http://delkinoem.com/oem-login/register-form.php.
./mmc readsmart /dev/mmcblk0
Calculated remaining life 100.00%
Good block rate 286.86% <-- this a bug that needs to be fixed
Remaining spare block count 78
Power cycle count 59
Abnormal power down count 0
Currently we only report a subset of the SMART data read from the card. The project could be modified to return the full data set if desired.
