If it's not new and has data you need, see if a data recovery expert can help.
it is okay if the files will not be recovered, the hard drive is more important to be fixed than the data in it.

Sorry to say that your HDD is dead as a dodo. When you try to initialise it says it can't find the sector requested. In this case it is the all important sector 0 - the very first sector on your HDD. The initialisation process writes the MBR code in sector 0. If it cannot read/write into that sector that is the end of the story.

Sector 0 is the heart of the HDD. When that sector has gone bad, nothing can be done.

Hello!

Unfortunately, it does look like your drive has suffered damage and the system cannot recognize it correctly, and give access to it. :/

Did you try connecting the drive in another USB port and on another PC, like DavidE suggested? Was the result the same? Youc ould try one last thing, to boot to a Live Linux-based CD and see if the drive would be recognized there.

Tutorial to create live Peppermint CD by Golden:
Peppermint Live CD/DVD/USB - Create for Emergency Backup

If it's not, then you should replace it, because as Jumanji said, it's sectors 0 even cannot eb found, meaning the drive is dead. :/

May I know by the way what caused this problem?

The most common cause is ageing and loss of magnetic properties in the platter. Wear and tear of the mechanical parts also can cause the heads scrape the platter. Any impact - like dropping the HDD- also can do that.

When a HDD starts developing bad sectors on its own accord, usually there will be some warning signs and symptoms. Even the OS can alert you to backup all the data.. But when Sector 0 becomes a bad sector it will be a sudden death.Here today, gone tomorrow.
