iMac Intel 21.5" EMC 2428 Hard Drive Replacement

Introducción

Upgrade your hard drive for an increase in storage space.

This guide also includes steps to upgrade your iMac's hard drive with a SSD. It describes how to install the SSD's temperature sensor so that the Mac's fans will operate at the correct speed.

Before beginning any work on your iMac: Unplug the computer and press and hold the power button for ten seconds to discharge the power supply's capacitors.

Be very careful not to touch the capacitor leads or any exposed solder joints on the back of the power supply.

    • Before beginning, unplug your iMac and lay it on a soft surface as shown.

    • Stick a suction cup near each of the two top corners of the glass panel.

    • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

    • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent.

    • Gently lift the glass panel perpendicular to the face of the LCD enough to clear the steel mounting pins attached along the underside of the top edge of the glass panel.

    • Pull the glass panel away from the lower edge of the iMac and carefully set it aside.

    • During reinstallation, be sure to meticulously clean the inside of the glass panel and the face of the LCD as any dust or fingerprints trapped inside will be annoyingly visible when the machine is turned on.

Hi guys, the tools arrived today and I did already chage the default harddisk against the WD Velociraptor 500GB. For now everything is working fine. The iMac is in the middle of restoring the time maschine backup. Everything worked out as described. Excellent! I was just a little surprised by the magnetic forces which one needs to overcome gently...

Is there a temp sensor that monitors the HD? I did the upgrade but now my fan is always on. I must've done something wrong.

Did you use the same brand hard drive? Did check the instructions about cable orientation on the hard drive? Did you double check the LCD thermal sensor cable?

Take a glance at this page for full explanations:

I had the same issue here (after replacing the original HDD by a 1TB WB Caviar Blue) and it has been fixed by this utility.

HTH,

In response to the software, that does work, however, it can be taken care of hardware wise if our recommendations are followed.
