WD Elements 6TB freeze

Hi open a case but my hard disk out Warranty. I make some test in windows it don´t show any damage with Win DLG Data life Guard and the test don´t any issue in theory : I don´t know if i only need to pass surface test or format the unit?
One Week ago when i use my torrent client to download at one or two minutes they freeze the computer and i can´t do nothing because is freeze i couldn´t force closing. What can I do?
Is my unit defective? My unit is NFTS but seen with three years i think somethig is wrong.

Hi @unai
Have you opened a Support Case? If not opened, for more information, please contact the WD Technical Support team for the best assistance and troubleshooting:

Run a surface test on your hard disk since Win DLG didn’t show any issues. Use Windows’ error-checking tool by right-clicking the drive and selecting Properties > Tools > Check to fix any errors. Backup important files if the drive is accessible. If it passes the tests but still freezes, consider formatting it, but this will erase all data. If problems keep happening, the hard drive might be failing, and you may need to replace it.
