Tonchi,
I'm not a tech anymore
. Actually, I work in a related, field (Information Security/Assurance and some work in Computer Forensics). I have to know how all this stuff works as part of my job. One of my responsibilities for customers happens to be testing Microsoft patches and establishing patch management, auditing, and security hardening processes for Windows and related products.
Another one of my responsibilities includes data recovery for investigative purposes from hard drives and other sources utilizing approved tools (such as Encase) for two of my customers. This gives me exposure to how to recover data from hard drives using any number of toolsets and equipment.
However, I do call the Philadelphia area home.
