it operates normaly except when i want to explore the files in it , i don’t see anything , when i check 

the amount of space usage it shows me that im using about 700gb .

surprisingly when i reboot to ubuntu(linux) i see the files , can someone help pls .

thnx a lot .

What if you try chkdsk on the drive in case there’s a problem with the NTFS file system?
