How to choose the correct brand hard drive
I am in the process of replacing a hard drive on a friends iMac. I have looked over the forums, but can't seem to find an exact answer to my question. I noticed that when I went to the hard drive section compatible with the iMac ECM 2390, there are three different hard drive brands compatible with the computer. In the info under the hard drive, it mentions that to ensure compatibility, you must purchase the same brand hard drive that was in the computer before the replacement. Is there any sure way to find out the brand of hard drive I currently have in the computer before taking it apart? I can certainly take it apart to find out, I just don't want to do anything unnecessary.
Thank you in advance for your help.
Is this a good question?
