Problem and I do not know what.. pls read and help me. Seagate Hybrid drive issue?

[jdaniel]

Hi guys so I have a mid 2012 MBP 13". As soon as I got it I put in 16GB RAM and a Seagate Hybrid drive 1GB. A few months ago the drive died and I had to send it in for replacement, in the meantime I bought a 750GB WD Caviar, which I now use externally as a back up drive and with superduper doing the back up.

My set up is also connected to a TB display.

The incident:

I shut off my mac and when I tried to start it up again, it hung on the apple logo page in the white/grey background with the spinning circle of sorts and nothing will make it move past it, I tried restart, I tried cmd option p r .... so last resort I took out the drive and put my bootable back up in there and although it is slow and starts up with a grey login,it starts up and it works, but everything seems slower, I get more spinning balloons or whatever they are called, which I never get with the other drive... the other drive is connected to the Tb display and in turn to his MBP and it seems to be ok, connects fine, so does not seem to have failed... but when I put it back in again, it still will not boot. So I am back on my back up drive and i am tired of fiddling with it.

I was hoping someone could suggest what I could do to:

1. Find out why it will not boot, is it a motherboard issue, or hdd
2. How do I find out why I am getting spinning balloons with the caviar..

THANKS !!!!!

Your post is hard to read.

1. Try replacing the SATA cable.

2. It's slow because it's not a SSD. Or maybe the SATA cable is causing problems.

thanks for your suggestion, but why would it work with my caviar drive and not with my seagate hybrid? And consistently so? And why would it stop working all of the sudden and still work with the caviar drive I put in? if it stopped working altogether that would make more sense.

Well my hdd are supposed to be the fastest on the market when doing simple stuff it should not show the beach ball at all.... but my main issue is when I was using the hybrid drive, I NEVER once saw a beachball..but now with the caviar....

anyone else had this issue ?

Today I came back home tried starting up the mac same problem, it seems if I disconnect the power, the connection to the Apple display the problem goes away and it starts up properly.
