Can't identify which SSD is source

[PDA224]

I'm trying to clone 1 external usb ssd to a second external usb ssd. They are both connected to sata adapters.

The problem is when it comes to Identify Source Drive, which shows both drives, I can't figure out which one is the real source drive as the adapter name and drive size only appear and that's identical for both drives. I can't remember but maybe there's an SDB and SDC. Regardless, I have no idea which one's the source.

Any ideas?

Thanks

Start a second screen: CTRL+ALT+F2
Use lsblk -f to list partition sizes - which should allow you to distinguish the drives.
Switch back to Clonezilla with CTRL+ALT+F1
