WD My Passport Ultra Files Vanish

Hello,

I recently got a WD My Passport Ultra 2TB with a USB-C Type connect.

I backed up all the data from my old external drive to the new one and continued working with it fine.

I tried to access a folder from the recent accessed folders list which comes on the file explorer of windows but got an error that the folder could not be found and was either moved or deleted.

So I went to the location where the flder was meant to be to find that it was completely missing.

Similarly an excel file that I worked on and then saved with a different filename had also vanished. I can see the file in the recent documents list when I launch excel, but the file cant be opened as it is just not on the drive anymore.

I tried using WD Data Lifeguard and the scan says theres nothing wrong with the drive. I also ran a couple of data recovery applications but it cannot find the missing files. The Excel files are really important, and I really need to know what has happened.

Any help will be much appreciated.
