简介

升级您的硬盘来获得更大的存储空间。

更换iMac Intel 21.5“中的硬盘。[...]本指南还包括使用SSD升级iMac硬盘的步骤。它介绍了如何安装SSD的温度传感器,以便Mac的风扇以正确的速度运行。 [...]在开始对iMac进行任何操作之前:拔下电源插座,然后按住电源按钮10秒钟,使电源电容器放电。[']要小心不要触摸电容器引线或电源背面的任何暴露的焊点。

    • 在开始之前,将您的iMac如图所示放倒在柔软的表面上。

    • 在玻璃面板顶部的两个角上放置吸盘。

    • 要使用我们的吸盘时,首先将吸盘的活动手柄扳动到与玻璃面板平行位置。 在吸盘轻轻地吸在玻璃面板上时,扳动活动手柄使其与另外一个手柄平行。

    • 如果您的吸盘无法吸住,尝试使用温和溶剂清洁玻璃面板和吸盘。

  1. 轻轻地竖直提起玻璃面板到足够高的高度来接触玻璃面板顶部下的卡扣。 将玻璃面板拉离iMac的下部,并将面板放在一边。
    • 轻轻地竖直提起玻璃面板到足够高的高度来接触玻璃面板顶部下的卡扣。

    • 将玻璃面板拉离iMac的下部,并将面板放在一边。

    • 在重新组装时,请确保已经清理了玻璃面板内部,和LCD表面。当打开电脑时,没人希望看到屏幕里面满是 灰尘和指纹,这样你会抓狂的。

Make sure the hard drive is of the same producer and it has a temp sensor connector. It's the only way to ensure that the heat sensor connector will fit into the hard drive's socket. If you don't plug in the temp sensor iMac's HDD Fan will rotate at its maximum speed, ie. over 6000 rpms - the noise is extraordinary!!!

David Relich - 回复

I replaced my internal HDD on my 215" iMac, but the iMac can't get access to the new hard disk's (Seagate Barracuda Green) temperature sensor. The HDD fan in the iMac steps up the RPM, and over about 15min reaches 6000RPM (VERY loud) and stays there until machine is shutdown or put to sleep.

I found a fix for this: http://hddfancontrol.com/HDDFanControl/H... - this tiny piece of shareware software allows the iMac to see the temperature of the drive via S.M.A.R.T., and therefore the fans react according to the correct temperature again!

Ian - 回复

One thing Andrew left out here, which I discovered on my own, is that even if you have the temperature sensor connected to the correct pins, you ALSO have to make sure that it is 'oriented' properly.

On the sensor connector (the little head that plugs into the hard drive) I saw a little white dot on one side, which it turns out, indicates that's the 'top'. So on my iMac, you have to make sure when you connect the temp sensor connector with the white dot showing.

Otherwise, I got the 6000 rpm fans.

Success. For any interested people, it's about an hour - going slowly. Now that I've done it, I assume I could do it again in 15 minutes if I had to.

Just have the right tools handy, the T 8 and T 10 bits in particular. Getting off the display screen is easy. The screws are harder than you'd think because of the magnets, but they're not that bad. I recommend having tweezers to help pull them and place them later on.

Overall, the thing that worried me most was the fan issue. And, so far... it's not an issue. I had a seagate 500 gb, and I replaced it with a seagate barracuda 3 tb hhd. Everything fit right into it, just as it did into the original. No optical sensor needed. No new sensor needed, period. No software needed. Nothing. Just put in the new hd, and it works. I'm very pleased, and very proud of myself. Good luck to anyone considering doing this upgrade. You can do it, really.

It's a pretty straightforward procedure. Took less than an hour. I replaced the 500GB Seagate Barracuda with a Seagate Barracuda 2TB, model ST2000DM001. So far, after about 30 minutes of use, it's working great, and I haven't had the fan problem, but we'll see what happens.

Kevin's advice about the tweezers for extracting and inserting the screws that attach the display to the case was right on (although I used a small pliers instead).

Before you begin the replacement procedure, I highly recommend putting the new drive into a hard drive dock, and restoring to it from a Time Machine backup. Try booting off the new drive once to make sure it works. Then, when you swap the new drive for the existing internal drive, it'll be ready to go with no further effort needed.
