Hi @Jitjai
If the Old Disk is not Encrypted you can simply attach it to your PC as secondary Drive and give Full permission to yourself and access the Data.
You can use icals to get full access to your self.
Example : icacls "C:\Users\UserFolderName" /grant Users:F
In case if the Disk is Encrypted using BitLocker or any other method the you need first Decrypted it using its PIN or Recovery key.
Hope this answers your question :)
Thank you.
