To check that your HDD is new and unused, you can use CrystalDiskInfo.
S.M.A.R.T. values cannot be reset or edited (without having access to specific manufacturer's tools). Your PC has automatically assigned a drive letter to your HDD and the name "Kesu" has been surely defined by the manufacturer - it doesn't mean that the HDD was used by someone else before.
Check the serial numbers, model and firmware version. If you can identify the info from the manufacturer, this means your HDD is original and unchanged.
You can also take a visual look to identify signs of wear like scratches, scuffs, etc... A brand new device must be free of any physical damage.
In addition, your HDD should be under warranty, and if it does, it is likely new.
If you can't find any info online about the current version of your hard drive's firmware, it could be a clue that it doesn't have the original firmware and is potentially counterfeit. Check also the name of the seller from which your hard drive was ordered.
If you bought your hard drive from "Kesu Official Store", then there's nothing to worry - you've an original hard drive from Kesu. This company seems to be legitimate and reviews are positive on AliExpress.
However, the quality of their hard drives seems to be cheap... Your HDD should do the job, but if you prefer a reliable external storage to keep your data safe for a long time, I would advise you to go with a reputable brand such as Seagate, WD (Western Digital) or Toshiba. You can also keep your Kesu hard drive and store a copy of your data elsewhere, such as on another hard drive or in the cloud, just to prevent data loss in case of hard drive failure.
