Hello,
I ran the next command:

gunzip -c someimage.img.gz | sudo dd of=/dev/rdisk1 bs=1m

deleting all the content/partition of disk1 (the good destination should have been rdisk2). Could be possible to recover the lost partition/files of disk1? I have a lots of photos in it.

Thanks!

If you had several partitions on this disk, you can try TestDisk to recover them (recovering the first will probably be impossible). You can also try PhotoRec to recover your data.
