How do i format my internal hard drive to use in my xbox as a replacement?

You dont

Internal drives can't be replaced by users on xbox one or higher

Doing so will lead to console bans you can take it to BestBuy for repairs

Only external drives can be replaced by users

Xbox hdds are setup by factory and keyed to the motherboard

It’s an intentional feature, Xbox hard drive’s have custom formatting that is not compatible with standard computer dries. You must use an official Xbox drive that is pre-formatted for the Xbox 360, Xbox one internal drives or not user replaceable

I thought it was installed on the Xbox internal storage. Yes, you can just format the external hard drive. Do you know how to do it, my friend?

if i buy a new hard drive or Xbox do i need a data transfer cable to transfer from hard drive to hard drive?

Can you (just for testing purposes) unplug the Seagate hard drive and try to install one game on your internal hard drive?

If that works, try if it's possible to format the Seagate Harddrive on a PC, and do NOT use Quick format. With Quick Format, only the "table of contents" of a hard drive get overwritten, but by doing a "regular" format, each part of the drive will be formatted,
and you can check if parts of the drive platter became defective.

If the Format was successful, try to connect the drive to your console again, and have the console format it again for game storage.

If the drive shows signs of corruption or is unable to be formatted on PC, check on the Seagate website, if the drive is within warranty and can be replaced/repaired.
