Samsung Galaxy S5 no PARTNAME warning

[tomdearden]

This is an amazing tool - thank you so much for taking the time to write it!

That having been said, it asked me very politely to raise an issue while I was experimenting with it, so I am.

I'm backing up a Samsung Galaxy S5, running Cyanogenmod 13 and TWRP recovery. The output from tetherback is:

Backup complete.

On further investigation, ie. running tetherback -0 to get a list of partitions, it seems as if this should be an expected warning when tetherback encounters an external SD card, as this seems to be what mmcblk1 refers to on this device:

So this is perhaps not so much an 'issue' as a (semi-)useful bit of info for anyone running this on an S5 who wants to know why this warning appears?
