I have accidentally deleted some precious photos and videos from my SDHC card. I can't find them on it.
And I googled, many posts recommended my to try some SD card recovery software.
I don't know which one to choose, and I also found two free SD card recovery software. They did find some of the deleted files but can't find all.
What should I do? Should I buy one to recover and which one is the best? If the software can't recover the deleted files from SD card, can I request a refund?
