WD passport data transfer

While transferring data from PC to WD Password External Hard Drive sometimes very light tik tik sound is heard. There is no problem with data transferring or accessing the data. I would like to know if it is the usual sound during data transfer or do I need to worry about Disk failure. Is there any way of identifying sounds that are normal and sounds that are abnormal during working of a WD Passport External Hard Drive.

None of my WD Passports “tik tik” or “click”

I would highly advise you backup your data now in case it fails.

Even without any abnormal sounds, you should always keep a backup of your data to avoid worrying about potential disaster.
