stanza.richi I was trying to transfer al my data/files/photos from an older WD 500gb external drive to the Extreme SSD 2TB drive. I was using an Anker hub connected to my IPP with both drives connected to the hub but could not read WD to do transfer. I downloaded the File Browser app and all my drives plus file apps (built in and Documents by Readdle) appeared. Transferring from any of them to another was now possible.
I really like the Sandisk SSD Extreme drive. Works great
