new internal sshd not recognized

Hi all,

So I just bought a Seagate 1tb SSHD to replace the 256GB 5400rpm HD that originally came with my MBP mid 2009. I also bought a SABRENT 2.5" SATA hard drive to USB 2.0 enclosure so that I can connect it to my MBP and clone my current HD into it. However, the problem is that when I connect the Seagate SSHD (in enclosure) to the MBP the MBP does not recognize it! I'm runnin OSX 10.9. The enclosure lights up and I can feel the SSHD spinning but it does not show up on the desktop nor on the Disk Utility, nor does it get recognized! I connected it to my older laptop running Windows XP and it was recognized so it seems to be a software issue. Can someone help?!

Does the enclosure have its own AC power supply or is it USB Bus powered?

If it is bus powered your Mac isn't putting out enough power from only one USB port to properly power up the drive. Your Windows XP PC is putting out enough power for the drive to actually work.

It is USB BUS powered.

Update:

I disconnected and reconnected the enclosure/SSHD combo (the enclosure came with an extra USB plug for extra power) and after a few (quite a few) tries it actually recognized it. I also hit the option+command+"P"+"R" keys as suggested elsewhere herein a couple of times after restarting before this so i'm not sure which one's responsible for making it get recognized. I'm in the process of cloning the drive using CCC but only saw "Journaled" as an option prior to formatting the disk rather than the GUID/Journaled format everyone mentions, so I just chose "journaled". So far only one error pertaining to my phone back up not being able to be cloned but i'm not concerned over that. I'll see tonight if I can boot from the cloned drive (assuming it is recognized!).

thanks

SOLUTION TO THE PROBLEM BOOTING A NEW SSHD.

I have a mid-2009 15" MBP. I purchased a new 1TB Seagate SSHD that would not boot internally. Did tons of research and found out that I either had to jumper my new drive to 1.5gbps or get a new internal SATA cable. I opted for the cable. The drive still wouldn't boot internally. Did more research and found that others had connected their old HDD externally with their new drives internally. Did this with the old cable, and nothing happened; did this with the new cable and the drive was recognized, but unreadable even though I had already cloned it. Re-cloned it using Carbon Copy Cloner (with the old drive external, new drive internal with new cable). The new drive booted after this with no issues.

Order of steps:

1) Get a new cable. ifixit and Amazon both have them. Make sure you get the right one.

2) Install the new cable (ifixit has videos/guides)

3) Install the new drive internally.

4) Hook up the old drive externally.

5) Restart holding the 'option' button.

6) Boot from the old drive.

7) Format the new drive with one partition using disk utility (make sure you click options: GUID partition!)

8) Clone the old drive to the new one using CCC (do the recovery HD option for sure)

9) Verify the new drive using DU; repair any errors.

10) Boot from new drive to make sure it's working ok and that everything runs.

11) Voila!

Can you please refrain from resurrecting old posts, these notifications for a thread that is old are annoying.

Pick someone with a new issue, not one that was dealt with months ago. Or make a new post of your own detailing the method for those who need it.

I experienced error -50 messages when attempting to write data to internal hard drive, it could read, just not write. I thought it was the drive on it's way out so I ordered a new Seagate 1TB SSHD.

When I put it in it wouldn't show up at all internally

I replaced the internal SATA cable and all is normal again now.
