1.0TB Hitachi Travelstar 7200RPM showing as 7TB in Disk Utility

I installed a 1TB Hitachi Travelstar drive in my 2006 MacBook Pro. The Disk erase will not erase the disk and the hard drive shows 7TB and not the actual 1TB. I verified with OWC that this drive is compatible with my MacBook. Tried chatting with support at OWC and they had me send the drive back and sent a new one thinking it was a drive problem. The replacement drive arrived and I am having the same problem.

Does anyone know why this is happening? In the "old days" I remember having to configure a jumper switch so that the drive showed as a master and not a slave drive. There are no jumper switches on this drive.

Any help would be deeply appreciated. Thank you in advance!

NOTE: When I attach this drive externally via the USB port, it will erase and initiate. Even after it's initiated, and then installed internally on the laptop, the same problem exists.

Got it resolved. I removed the drive, hooked it up to another Mac via the USB port, re-initialized it and then installed the OS. I then installed it back in the MacBook, hit the power key and voila-we have life!

Check if there is any firmware updates on your Macbook and HDD.
