Just a note to those that came up with the idea of backing up your cards (SD in my case) without a computer. It has been very helpful to me and I just wanted to say thanks to the good folks on this forum.
We are flying and I hate to bring the laptop along for two reasons. One the bag and all its contents is heavy and the second is that I tend to work on the photos each evening which the wife is not always happy about.
So after reading several different threads on the subject. I purchased the following on Amazon for $82:
Seagate Backup Plus Slim 1TB USB3.0
Anker Ultra Slim 4 Port USB3.0 Powered Hub
WEme Micro USB OTG adapter
I have a 3.0 card reader and an Android phone (Note 4), so I cobbled everything together and of course it didn’t work. After reformatting the HD to FAT32 (google is your friend and Youtube is your instruction manual) I had it up and running fine.
I have to say it brought a smile to my face, technology is truly amazing.
Thanks again for the great idea.
