Loss of Data on external My Book WD6400H1U-00

Can someone help me please. my external hardrive was working normal. suddenly I lost access and I cannot see the files anymore 400 GB. The properties still reflect the size used, but I cannot see or access any files. Please let me know if I can use any software to access the files. I have all my family photos and videos.

Thank you.

Hi dude!

You can Google a free software called TestDisk, it is very helpful to repair drive partitions and recover data.

Best of luck!
