Final answer:
To unlock the disks, one would need the correct decryption key or password for encrypted disks, administrative access for disks locked by OS permissions, or a vendor-specific tool for physically locked disks.
Step-by-step explanation:
To unlock the disks you've received, you could use various methods, depending on what type of 'locking' you are referring to. If the disks are encrypted, you would need the correct decryption key or password to unlock them. For example, if the disks are using a system like BitLocker, the correct passphrase or recovery key would be required to gain access. If the disks have been 'locked' using operating system permissions, you would need administrative access to change the permissions or take ownership of the files. In some cases, the disk may be physically locked to prevent it being used in other systems, and in such cases, you might need a vendor-specific tool or command to unlock it.
