Help solving error

#1

Iam using Etcher to flash a large image on a external HHD (256gb retropie image).

It does finish but with a error; ‘1 failed device
Source and destination checksum do not match’

Is there a way too remedy this? what does it mean?

Thank you

@Papabearbuddy it means that when we try reading back the external hdd, we don’t get the exact same bytes that we’ve written to it. In general it means that your hard drive has issues, try flashing something else.
