My icons on my WD external disc disappeared

Hello today I connected my WD disc to my computer and when I opened it on my computer it didn’t show anything stored on it. I assume that files are not lost because in properties it still shows that 70% of disk space is taken. I tried it on multiple computers and it does the same. Does anyone has any idea how to locate files and folders again?

Thank you 

if it shows that the 70% of your files still in the drive, you will need to use a recovery software to see if you can get your files back. you might be facing data corruption.
