The PS4 game console might go out of action for several reasons, that’s why users buy a new one. But there’s a question that many users keep asking that whether they can put their old PS4 internal hard drive in the new one or not. In fact, there’s nothing to prevent that from happening. That’s because the internal hard drive of PS4 is not special for the console it’s in. Also, it’s not protected with a secret key or a serial number that hinders anyone from using it in another PS4. That is why you don’t have to worry here. YES, you can use the old PS4’s hard drive in the new PS4, there will be no problem at all.
But there’s a very important point here that you have to heed to. It’s that if you’re thinking to use the old PS4 hard drive with its previously-installed content in the new PS4, then unfortunately the answer is NO. You will need to wipe off all data before you are able to use it again in the new PS4.
So, back to the original question, the proper answer should be: Yes you can use the old PS4 hard drive as long as you FULLY erase it.
But what is that?
It’s because every PS4 unit has its own license (serial number) that the system software uses to register the console. Now, when you try to use this licensed/registered operating system with a new PS4 (which also has its own key), a conflict will occur and the system won’t start until you fully erase the hard drive.
So, what’s the workaround for this situation? Well, if your data is so precious, go and make a full backup on an external hard drive. But the problem that arises here is when your old PS4 is already out of action and totally defective. Then, this is a real mess and there’s no way to resolve it. I can only think of repairing the old PS4 then take a backup of its hard drive. I know this doesn’t sound logical, as you have bought a new PS4 because the old one is dead.
But in case the old PS4 is still working fine, go and back up your data to an external HDD. Make sure you have a PS4 compatible external hard drive, otherwise it won’t fit.
Using an old PS4 hard drive into a new PS4 is possible in two cases only. The first case is when you fully erase the drive and get it absolutely clean for the new console. In this scenario you’ll lose all your data and have to download/install them again on the new console.
As for the second case, you’ll need to back up the content of the old PS4 hard drive to an external HDD. Afterwards, you erase the HDD and use it inside the new PS4, then transfer the backed-up data to the new console. We couldn’t think of any other solution for this issue.
