HDD

Since I replaced the HDD of iMac (21.5-inch, Late 2009), I will explain the procedure at that time in detail with photos.Models around this time are easy to disassemble, support OS up to 10.13 High Sierra, and hardware performance is not bad, so I recommend them.

Since I replaced the HDD of iMac 2006, I will explain the procedure at that time in detail with photos.I will also explain the advantages and disadvantages of HDD / SSD replacement, the necessary tools and types of HDDs that can be used, and precautions when disassembling the iMac.
