Another question for the MMC experts. Data storage checksum.

Colleagues,

Do the MMC/SD cards store CRC (or checksum) along with data? Is there a mechanism that detects or prevents data corruption during storage?

Thanks,
- Nick

Look in this section in the Sandisk MMC manual:
Quote:
Defect and Error Management

It says there is built-in ECC.
