Why there isn’t any A1355 tutorial? HDD upgrade.

Many thanks for the answer.

Do you mean I cannot use the same cable for any HDD brand? Maybe I misunderstood...

Apple used a special sensor cable which was designed for a given vendors drive so a Seagate cable won’t work on a WD drive. This is independent of the SATA or power connection which is standard.

I would add some drives pull more current than what Apple used so review the drive your TC has now to figure out what your new drive need not exceed.

@rx78 I am specifically talking about the hard drive temperature cable. Apple started using hard drives with priority temperature sensors in Mid 2009. No matter what the intent of Apple, its affect was to stop off-the shelf hard drives to work correctly without getting run away fan issues. Since we do not have a tear down of this exact model I cannot tell if it has been effected. You will need to look at the hard drive and see if the temperature sensor plugs into the drive next to the SATA plugs or is attached to the drive (usually in a little plastic attachment bracket and held in place by tape. If it plugs in, it is one of the newer drives and will need a specific cable. Those parts are:

Seagate 922-9216

Hitachi 922-9215

Western Digital 922-9217

Is there any way to understand which kind of HDD (brand) is mounted inside my Time Capsule, without opening it before? Thanks in advance.

I have an A1355 on which the hard drive just died. Opening it I found it was not using the proprietary temperature cables found in iMacs from the same time, but an external temperature sensor taped to the hard drive.
