Unfortunately, the replaced electronic system didn't improve things, so the disk was unscrewed and opened up in a clean environment. When doing so, no dust can be allowed to come into contact with the hard disk or the magnetic strips/heads. A clean room is not necessarily needed to accomplish that. Powerful extraction systems and an air ionizer are really all that's required.
An ionizer is required in order to clear the air of foreign particles. The negative ions that are emitted bind these harmful substances, which are then big enough to fall to the floor under normal conditions. However, thanks to the powerful extraction system, they're sucked away from the work surface.
After opening up the drive, CBL checked to see that the disk heads were tilted in the center of the disk. The cam must be moved carefully by hand into its resting position. Normally the heads only get stuck if the hard disk receives a strong blow from above or, with a little bad luck, if the notebook shuts down after it's already been packed up.


Thank you. This is informative. I really cried my heart out when someone stole my external hard drive and when my computer crashed. I usually relied on cloud storage but some of it are really disappointing. I haven't tried firms like CBL Data Recovery or Ontrack for hard disk recovery but I did try dtidata. I find it decent. Have you compared these data hard drive recovery? What do you think is the best?

How do you think DTI fared with CBL or Ontrack? Any thoughts?
