SSD Cloning fails on both Disk Utility and SuperDuper?

Hi all,

I own an early 2011 MacBook Pro that has begun to slow down to the point where its basically unusable. I recently updated my RAM to 8gb (which is the max) and have now decided to upgrade to an SSD (the current hard drive is a stock 500GB drive). I bought a Samsung 860 Evo and also bought a new SATA/Hard drive cable.

I initially attempted to clone the SSD using disk utility, but that failed after it was about 25% done and read “Could not restore- Input/Output error”. I read online that my old SATA cable was likely the cause of this. Today I replaced the SATA cable and also added electrical tape to the aluminum chassis.

I then attempted to clone my hard drive, first using Disk Utility and later using SuperDuper, but to no avail. Now what? I have heard that this might be a hard drive issue , but exactly how should I go about this? I only have about 90gb worth of stuff on my computer, so I wouldn’t mind using a Data Migration software and only installing the OS to the SSD.

Literally any help is greatly appreciated. Also, sorry for the long post, I’m new here…

What year HD cable did you use? What SSD are you looking at? How much RAM are your running?

by

I bought a mid 2012 HD cable, as those use full 6gb/sec speeds (my defualt cable uses 1.5 or 2 I'm not sure). I also bought a Samsung 860 Evo. I have 8gb RAM.

*Apple officially supports a maximum of 8 GB of RAM, but as first confirmed by site sponsor OWC, this model actually is capable of using up to 16 GB of RAM with two 8 GB memory modules.

Hard Drive

Do not clone. Cloning went out with the advent of the Repair Partition.

According to what operating system you are planning on using (below High Sierra format the drive GUID) (above, format the drive APFS).

Now install your system. When it starts to set up, have your old drive hooked up using a SATA to USB adapter. When it gets to the point of asking if you want to migrate the data from an existing Time Machine Backup or mac boot disk, select what you have and migrate your Apps and data.

Make sure you have protected the new cable:
