Thank you so much! The last time I reformatted the card to exFAT and reset the WFD to factory settings, it did not resolve the issue. But it is now working! It feels almost like some sort of voodoo.
I’m nost sure if it made any difference, but what I did differently this time:
- erase/format at the disk level instead of the volume level
- increased security level to writing zeros (1 pass) instead of fast erase
After resetting the drive as instructed on the kb link, I unplugged the WFD and turned it on. Connecting the MacBook Pro to the SanDisk network and typing in www.sandisk.com brought up the details of the WFD! And the iPhone app connected to the SD network was able to connect to the WFD and see that it is empty.
Thank you again for encouraging me to try it again. Your input is much appreciated.
