If that is not enough, throw away the SD card; I intentionally spent most of the time writing that answer on explaining why it's mathematically hard to make reliable memory out of bad SD cards, but you seem to choose to cherry-pick the information out that it's possible. | |

But it also seems to be more oriented to consistency check than to error repairing. I've read the manual of integritysetup and couldn't find if I can increase the ECC amount. The default of service data for a test 128 MB image happened to be only around 2 MB, that's too few to assist with fixing flaky bits. | |
