Flash to SSD failed

SSD is connected via SATA which I already override the unsafe mode. Here is the log

Hello @dawnslayer – these logs indicate it actually flashed the file successfully. Are you on Windows, by chance? Perhaps the Checksum validation failed if Windows attempted to write it’s hidden system folder onto the drive, while the verification was still taking place (a commonly occurring issue that we see). It might be worthwhile to try booting the SSD in a machine, and see what happens.
