Copying files from iPhone 7 to PC with File Explorer cause the message "0x80070141 the device is unreachable". Another possible message is "Can't read from the source file or disk".
I also got the message "Catastrophic failure" :)
What I have discovered
- The issue is occurring while copying files received from other contacts, for example via WhatsApp, not the photos and videos created originally with the iPhone.
- USB 3.0 does not work, but USB 3.0 powered one works.
Other solutions to try
- Open Settings on your iPhone > Tap Photos > Scroll down to find the section "Transfer to Mac or PC" > If you have chosen "Automatic", tap "Keep Originals" > reconnect the iPhone to the PC. If it does not work, try the other selection.
- Use USB 2.0 instead of USB 3.0.
