Hey everyone,
I am a new member here with an issue that I hope you all can shed some light on. I have a 2008 mac Pro running Mac OS 10.11.6 El Capitan. Recently I decided to buy a second hard drive and use it internally. I purchased a 3.5 inch Hard Drive (used; with a clean wipe) with 2 TB of storage. I attached this drive to the sled and slid it into the drive bay. Of course, the Mac was first shut down and the power cord was disconnected. With the second drive in bay #2 the machine would not boot. My next action was to shut the Mac down and hold the option key. When I did this a white screen showed up and my mouse cursor was up, however, no disk were available to boot into.
Confused, I decided to take out the second disk and try to boot up. After this second disk was out the machine, it booted perfectly fine into El Capitan. Called Apple and listened to a tech punch keys for 10 minutes before telling me he doesn't know what is going on.
