    Good Evening! Looking for some advice...

    My MBP has been acting funky lately, so I decided to do a clean 10.11 reinstall... I came home, supposedly wiped the hard drive using the disk utilities erase feature on the install USB drive. Then I went to install a clean version of the software and got an error saying the disk doesn't have enough room... It's a 1 TB HGST in installed last August that had about 700 gigs on it... Now it says it has 653mb available out of 1 TB. And I can't erase it anymore because it won't unmount. I've tried tech tool pro 8, I've used Terminal...

    Any suggestions? Thoughts?

    try booting into the recovery drive (restart and hold down command + R during startup) and launch disk utility from there. Make sure that when you create a new partition it includes all of the free space on the drive. If it says starting internet recovery, that means that the recovery partition has been deleted. connect to then internet when prompted (use Ethernet if possible) and use disk utility from there to reformat the internal hard drive
