I was trying to write an img file to an SD Card and just assumed it was the same disk as a minute ago but it wasn't. I have dd'd a Raspbian image onto my Time Machine disk and need a way to restore it. I'm trying Disk Drill Free to restore the disk but I am not sure if it is going to work.

This is the command I used:

```
dd if=/../image.img of=/dev/rdisk1 bs=1m

```

The size of the image was 1.5gb. 

Solutions / tips please!
