Anything that works at the logical block interface will not usefully wipe the device. SES 1 will physically hit every erase block on the device with 20V to blow it away. This happens suspiciously quickly (< 60 seconds typically) but that's just because flash is great.
- wolvoleo 9mo agoDoesn't that harm the flash? The OP seems to use this before using it again but such a high voltage seems rather destructive
- jeffbee 9mo agoIt consumes one of the erase cycles, of which a device has a few hundred or maybe a few thousand over its lifetime. It's not something you'd want to do frequently.
