My 500g wd external hd getting error "corrupt or un readable"

I have had my wd 500g external hd for several years and have not had a problem until now.

I am running windows 8.2 and everything was working fine. I shut down my PC and upon restarting

and trying to access my wd  hd keep getting error  “corrupt or un readable”. I tried to access using win xp, win 7

tried different pc all getting same error. Tried doing a chkdsk through command prompt halfway through it stops with error 600.

I can’t loose the data on this disk. What can I do??

See if you’re able to retrieve the data with a Recovery Software.

If the drive is still under warranty consider replacing the unit.
