I replaced my internal hard drive with one from ifixit (the 7200rpm 500GB). I had preloaded the harddrive with an image of the old HD system (Snow Leopard 10.6)and confirmed that it would boot as an external drive. MacBook Pro, 2.33Ghz, Model 1211.

Installed the new drive and it booted up fine. But when I reset the parameter Ram by holding down Cmd-Option-p-r the Mac would repeated reboot, not show the gray screen with Apple, reboot, repeat untill I released the keys.

Now it will not boot, it shows gray screen with Apple and spinning wheel, goes to blue screen with spinning wheel, then goes to blue screen with spinning wheel and repeats forever. I have to hold the power key to turn it off.

Booting with an external drive works fine and the system runs fine.

Do I need to open it back up and replace the Parameter Ram battery, or simply remove it?

I am having a very weird problem with my MacBook Pro 15'' Mid 2009 model.

I recently damaged my hard drive, so I decided to buy a new one, which is exactly the same model as the one that I had. A Seagate ST9500420AS 500 GB 7,200 rpm.

Now the thing is that, although my previous drive is damaged, it can still be recognized by the disk utility when I boot from the Snow Leopard Installation DVD. On the other hand, for some reason, the new one is not recognized by the Disk Utility! What's more, I connected an older hard drive that I had, with Leopard installed in it and still it doesn't recognize it. But If I connect it to the USB, it recognizes it and it can boot normally to MacOS....

Isn't it weird? To recognize only the damaged hard drive?

Does anyone have any suggestions? I am dying to get my laptop working because I have many things to do this period. I appreciate your help.

John

I was looking into a new iMac 21.5(27 is too big, I have a 20'' monitor for my Linux PC too) and I knew about this HDD sensor bull where i will make my fans run at full speed with no help

Apple, !^!* off with this, i'm a freelance technican, this really @@^%!^ me off because if I want to upgrade a client's drive, I need to be CERTIFIED by apple to get a drive for a client(or they won't sell it to me, just tell me screw off), and they have to pay crazy fees, screw that!

I REFUSE to upgrade these 2011 iMac's because of this, only the memory

Enough ranting

before I buy one, is there a workaround just yet so when Iget mine, i can replace my drive and actually work on the HDD's and not just memory, for my own and other iMacs

just to clarify how i handle iMacs, I will do HDD's on anything before the mid 2009 because of the issue and various ways to stop upgrades on the mid 2009, so it's mixed which ones have the HDD swapped, but all of them have memory done

The hard drive on my 3 years old 27" iMac has died.

The iMac model number is iMac11,1

The actual drive model is ST31000528ASQ

I would like to replace it with a 2T drive. Could you please suggest a model that won't result in fan issues (or any other type of issues such as vibrations, etc)?

Thank you!

I bought a wrong model (see model here: http://centralart3.dominiotemporario.com...), and I know the way to change, so I just want some help to teach me how and where to buy, because here in Brazil the HDD + the labor to repair (In Apple Care Network) is about $300,00 for 1TB HD.

So if I buy this (http://www.powerbookmedic.com/10TB-Hitac...), with this (http://www.powerbookmedic.com/Intel-iMac...) my iMac will run perfectly again?

Thanks and sorry for my english.

Recently, I decided to dig the TC up and see if I could replace the hard drive to bring it back to life. I followed the excellent manual located here on iFixIt and replaced the drive with a 1.5TB Seagate model.

After replacing the drive and powering the TC, the front light lights green for a few seconds, the fan started to go, and then everything shuts down. It does this every time I try to plug it in. If I replace the old hard drive back in the TC, it boots up with an amber light (which is what it did before.)

Thinking that it might be the power draw from the new hard drive, I checked the power consumption specs. The old drive consumes .680A @ 5V and .850A @ 12V. The new drive consumes .720A @ 5V and .520A @ 12V. Power consumption shouldn't be the issue - the new drive consumes less @ 12V and only .04A more @ 5V.

Just for grins, I also tried a 2.5" laptop drive and it produced the same result - green light for a moment, then powered off. It can't be drawing more than the original 3.5" desktop drive.

Any other thoughts here on what this could be? Possible, I guess, that the power supply is simply dying as has been mentioned so often previously, but the unit powers up with an amber light with the old drive, so I don't think that's it.

Is there anything special I have to do to the new drive in order to get it to be recognized? I formatted it MacOS Journaled but that didn't produce any special results.

Thanks in advance.
