SATA devices and NVMe devices support Secure Erase where such a command can be issued like this in the case of supported ATA devices. But I can't seem to find anything about how to erase an SD card in such a manner.

Is there a way to wipe the drive at a firmware level (perhaps some equivalent of Secure Erase or trim)? Or is the only way dd if=/dev/urandom of=[DISK] or some similar overwrite?

Thanks!

If there is, it'll likely depend on the OS whether you'll be able to actually issue that command to the card. Windows or Linux or a BSD? Is the reader USB-attached or PCI-attached? – u1686_grawity Jun 23 '19 at 13:51
@grawity either Windows or Linux (have access to both) and it's USB attached. – etnguyen03 Jun 23 '19 at 14:16
