Encrypted hard drives come in many forms. They can be created by the hard drive manufacturer as part of the hard drives firmware or as a third party software add on such as Symantec PGP or Microsofts Bitlocker.
Hard drive Encryption is becoming much more common especially in many large enterprise companies. Some hard drive encryption is more sophisticated than others, but in many data recovery cases we receive, a common flaw is the inability of the encryption software to overcome bad sectors on a hard drive. In most cases it results in partial or no access to the decrypted data on the hard drive by the user or even their I.T dept.
We have created an image and decryption process that allows us to recover the users data with the original file and folder structure intact. The time it takes to carry out this process will depending on the level of hard drive encryption used.
