I'm having a problem with a laptop so I need to return it and I'd like to completely wipe the SSD first. Is there an easy way to do that from sysresccd?

grant123,

The drive probably supports the security erase command.
You can give that command from hdparm

If you have a regulatory requirement to "sanitize" an ssd, realize that it will not meet approval with some organizations no matter what you do. One example is US DOD requirements for disposal of classified media. There is no approved method to sanitize an ssd drive that once held classified information, and the media must be destroyed using an approved destruction firm.

SSD drives may hold sensitive information in cells that have been locked out due to too many writes, and there is no way short of destruction to wipe out those cells once they are readonly.
