I transferred the images from the card to my computer with no problem. At the time, the card had over 5,000 images on it.
After the transfer, I got the "improperly ejected" message. I thought it was the EHD {which is used with Time Machine}, because it ejects itself all on it's own on occasion.
When I went to use the camera the next day, there were no images on the card.
I'm not sure where the confusion lies.
I ran the first program that chscag recommended, and only a handful of the 5,000 images showed up. Also, some of the images I took {after the 5,000 disappeared}, have gray areas at the bottom of them.
I believe that indicates corruption.
So....it looks like the 5,000 images are lost.
It also looks like there is corruption on the card.
Can that corruption be fixed? Is the card no good now? Will formatting/reformatting fix it?
Thank you
