  • From Laptop to Laptop with no extra components.
  • From Desktop to Desktop with no extra components.
  • From Laptop to Desktop with a SATA cable converter.
  • From Desktop to Laptop with a SATA cable converter.

To simplify the process, we recommend you to choose machines that do not require any extra cables or components for the drive to run on them. In case you do not have such possibility, we recommend using an external SATA-USB adapter.

Step 1: Remove battery and power from your laptop. For desktop computers, please remove eliminate the power from the contact.

Step 5: After you have connected the drive, you will likely not be able to open it, because it’s sectors are encrypted. However, because only some of the sectors are encrypted, enough to render the drive no longer openable, you may have a chance if you use a data recovery software to recover the files from the drive as you were scanning a lost partition. Most data recovery programs have support for scanning broken partitions, but we recommend you to try the following:
