In advance, thanks for your help.
Have loaded an sd card with data from a laptop and successfully accessed the data with the SL 101. When it was time to update, from the laptop, I deleted all of the data from the sd card and copied/pasted the data to the sd card. When inserted into the SL101, the card was empty. Thinking the card was at fault, I entered a different sd card into the SL 101 with the same wipe occurring. I am using Droid 4.0.3.
