WD My Passport 1 TB fell down. Now it is not detected, and i can hear a noisy sound. Would i be able to recover the lost data?
Several years of memories are in it 
Sounds like internal damage … i wouldn’t recommend trying to use it any further otherwise you’ll do more damage.
Yoru only hope is contacting a Professional Data Recovery Service
This is the reason why it’s so important to keep a backup(s) of any important data in case of failure, accidents, fire or theft.
Dropping a storage drive may cause your complete drive to become corrupt or unresponsive or RAW. As in result of dropping a drive, the impact on that drive may occur any type of physical damage to the drive which can make the drive unreadable.
You can give a try to any trustworthy data recovery software if that can detect or scan your drive. If the software detects the drive then there are chances to recover your data otherwise you have to seek help of data service provider.
