Problem initializing or formatting

[Enquiries]

Hi good morning

I bought 18tb EXOS ST 18000NMO00J, my purpose of buying it is for backing up my files.

Moving forward to make the long story short
This is the 2nd unit i recieved 1st 1 is damaged.

Every time i initialize the format its error.
It pop up like this

Erasing "ST18000N M000J Media" (disk4) and creating "Untitled"
Unmounting disk
Creating the partition map
Couldn't open device. : (-69877)

Operation failed..

I tried everything that is available format for other options but everything pop up same thing.

For info: ( ive tried it already 2 units)
* windows os (laptop)
* mac os (laptop)
We dont have desktop to try it.

Hope to hear from your team
Thank you.

I think both drives are damaged. It is better to get new ones.
