The method involves purchasing an HDD clone stand with two HDD slots. Insert this product into the source slot and an 8TB HDD into the destination slot. Make sure you don't put them in the wrong slots. If you insert them in reverse, the system data for copying will be erased. Next, follow the stand's instructions to complete the cloning, then install it in the recorder. Enter the settings screen by pressing the power switch and home button, and then format the HDD. The clone stand can be used as an external HDD, so it won't go to waste. Moreover, unlike sealed external HDDs, the HDD is exposed, providing good cooling and safety. Regarding the HDD type, the BXT3000 can be used even without AV commands. Fully functional HDDs that are no longer needed for your computer can be used, even if they are old. HDDs that display a "Caution" message in the CrystalDiskInfo diagnostic software cannot be used. You can specify the partition size after winning the auction.
