How To Upgrade HDD on Old iMac 27 Inch 2010 Faster SSD Samsung SATA 2.5
HTML-код
- Опубликовано: 11 сен 2024
- Ultimately, it is possible to upgrade the hard drive in these 21.5-Inch and 27-Inch Aluminum iMac models or upgrade or install a secondary SSD in the "Mid-2011" 21.5-Inch models and "Mid-2010" and "Mid-2011" 27-Inch models, but opening the case is a challenge and it is definitely not for those without significant
Unfortunately, taking the computer apart -- which is challenging enough -- is not the only obstacle to upgrading the hard drive in these Macs.
OWC also discovered that the "Late 2009" -- and subsequently introduced "Mid-2010" -- models use a "connector that seems to use the drive's internal sensors" rather than an external sensor like earlier 20-Inch and 24-Inch Aluminum iMac models.
Originally, this meant that the most straightforward way to upgrade the hard drive was to "replace the drive with another model from the same manufacturer that [OWC or another third-party has] confirmed works properly with this thermal sensor cable". OWC provides a list of compatible drives. Readers also shared reports that taping an external temperature sensor to a hard drive or SSD that does not have an internal sensor will work in these models, but this method is risky.
Thankfully, though, OWC subsequently developed a custom digital monitor that "talks Apple SMC" and "maintains proper temperature reporting and Apple Diagnostic compatibility" for these models and sells it as part of convenient SSD Upgrade DIY Kits. Although it still is fine to replace the hard drive with another model from the same manufacturer, this OWC solution provides many more options.
As again found by OWC, if an SSD is not installed at the time of purchase in the 27-Inch "Mid-2010" models -- the iMac "Core i3" 3.2 27" and "Core i5" 2.8 27" -- the connector cables and mounting bracket are not present. It still is possible to install a 2.5" SSD in addition to the hard drive if an SSD is not installed initially, but one will need the proper connecting cable. It also is worth noting that if a 27-Inch "Mid-2010" iMac is configured with an SSD, but without a hard drive, the hard drive temperature sensor is not present either. OWC now provides the proper cables and sensors.
For the "Mid-2011" models, OWC once more touched off a firestorm across the blogosphere by reporting that Apple had gone even further in the company's effort to restrict hard drive upgrade options:
For the main 3.5" SATA hard drive bay in the new 2011 machines, Apple has altered the SATA power connector itself from a standard 4-wire power configuration to a 7-wire configuration. Hard drive temperature control is regulated by a combination of this cable and Apple proprietary firmware on the hard drive itself. From our testing, we've found that removing this drive from the system, or even from that bay itself, causes the machines hard drive fans to spin at maximum speed, and replacing the drive with any non-Apple original drive will result in the iMac failing the Apple Hardware Test (AHT). . .
We've installed our Mercury Pro 6G SSD in that bay, it too results in ludicrous speed engaged fans and an AHT failure. In short, the Apple-branded main hard drive cannot be moved, removed, or replaced.
Needless to say, the obstacles to upgrading the hard drive in these models were quite disappointing. Thankfully, OWC's SSD Upgrade DIY Kits now overcome all of these obstacles for each line, and taking the computer apart and putting it back together again is the remaining challenge.
Hard Drive & SSD Installation Instructions
This is a difficult upgrade. It is recommended that a professional upgrade the hard drive or install an SSD in these models.

*pre-disconnected LCD. Do not follow step by step.
i m agree with you body "What did you use to control the fans since you are not using the fan sensor?" :)
probably Macs Fan Control
Gosh, remember when Apple designed their computers so you could upgrade them?
and the thermale sensor whare has gone ?
Did everything correctly my iMac won’t load os both apfs or extended journal just hangs up while loading any ideas what’s wrong?
went thru owc for ssd drive and ram installed it in my mid 2010 imac 27 now when it boots i hear beeping im mad
What did you use to control the fans since you are not using the fan sensor?
All good. Worked it out ;-) used a sensor of a earlier mac and changed the ends. Works like a charm
@@pjromez can you please share the sensor?
@@alessiobiancalana8414 yes please
@@PCgamingHD14 found the solution ... Just short the sensor cable . I used a wire between the two poles . The Mac it's running perfectly
@@alessiobiancalana8414 Thank you for your information.
I have taken the hard drive controller off the hard drive and plugged in the hard drive thermal sensor into it.
That worked? seems the easiest way...
I was given a perfect good as new imac 2010, was told to upgrade to a 8gb ram and a new SSD to have it run ios 10.13 any one know where I could get those parts for a good price and what brand exactly to get
The owc website has all of the detailed information and mac specific kits
Use OCLP (OpenCore Legacy Patcher) to upgrade to macOS 12 Monterey, it runs amazing on 2010 iMacs with an SSD
Caddy is like $ 5.99 .....
I replace HDD with SSD and then the computer fan started howling due to over temperature.
You broke sensor in change
The fan sensor is inside the old hard drive, so you need to use Macs Fan Control (free app) to set the HDD fan speed. I like 2,000 RPM.
I can’t get mine to read sad drive I’ve done steps formatted drive Mac can’t find it
