I believe the Hard Drive Cable is bad, it won't format, boot,
I cloned the old hard drive after placing it in a case and using it as an external drive.....so that I could increase to a 1T storage space, but I have not been able to boot from the new cloned drive...it was reformatted and partitioned according to CCC instructions.
Now, I want to reformat/erase the drive, but I can't get it to erase/unmount, or anything. Can you help??
Update (06/27/2017)
The Macbook Pro is mid 2009, I can't find a model # in About this Mac
The Hard drive is HGST 1T, I did try to erase it in disk utility, it said not successful.
The Mac will not connect to my WiFi at this time, so I can't plug it in to EveryMac Lookup.... When I click on my WiFi, the box for password doesn't even appear. This has never happened before, so I figure my unsuccessful attempt to erase the mounted internal HD has messed that up. I am booting from TM backup. Main thing I need is to get back online, now, or I won't be able to fix anything. I connect using a hotspot, and it's never failed me before.
Is this a good question?

Can you tell us what your exact model is as well as what hard drive you bought. There are a few possible issues here besides a bad SATA cable.
To help you identify your system you can go to this web site: EveryMac - Lookup and plug your systems S/N in. Once you have your models info paste the URL here for us to see.
