Macbook wont recognize the Hard Drive

I have older MacBook

Im getting the flashing Folder with Question Mark.

So I went to replace the Hard Drive and Im still getting it
The Macbook cant see the Hard Drive.

In Disk Utility, it cant see the Hard Drive either.

This is weird.

I opened the case and the Hard Drive is spinning but still cant get the macbook to show it or recongize it


Any help or ideas

Thanks

Can you install to a USB drive?

To the OP:

Try resetting your PRAM and NVRAM first. Try again.

thanks for everyones offer to help


The drive will recongnize via USB attached via one of those SATA dongles they sell.

But its only when the drive is inserted in the macbook that it wont register it for some reason


I will try to reset the PVRAM and RAM

It's sounds like an issue with the conection. It could be something simply a loose connection or something big. Get Apple to have look. I am sure it is a loose connection but check with apple.

Yea, im hoping is not the connection that goes from HDD to the motherboard.

Im resetting the NVRAM now see if that helps

this is weird and frustating
