The way in which an SSD stores data is totally different from how data is stored on a traditional hard drive. To fully comprehend how an SSD functions and provide insight into their forensic examination, it is necessary to understand SSD terminology.
Repetition by definition involves doing things over and over again. In repetitive work, these same types of motions are performed using the same parts of the body in the same fashion, time and time again. In activities such as typing, using a mouse, or referencing paper source documents, the affected muscles, tendons, and joints can be used thousands of times a day, week after week, year after year
Good investigators can keep lots of details in their heads. Great investigators document the details. Remember that a trial may come right away, or it could be years later, after you’ve potentially investigated hundreds more crimes, and after your memory has faded. One way to deal with this problem is to use a checklist to document everything you can about the crime scene.
The evolution in hiring starts with hiring the right people — without them, efforts to engage and retain staff become moot. The Industrial Age paradigm emphasized hiring for skills and experience.

Prints found on the adhesive side of things like duct tape, masking tape, and mailing labels, can be developed and lifted, but it’s often quite difficult to do so. The key is to use a specially designed product, called an adhesive side powder, for the job.
No wonder a recent survey of North American employees found that 87 percent of respondents say their work/life balance is negatively affecting their health. If you’ve been killing yourself trying to achieve daily work/life balance, it may be a pipe dream.
When I started working as a CSO in the ’70s, we’d go into a crime scene, take some photos, dust for prints, and bag the obvious evidence. Nowadays, CSOs have to do more. Changes in science and technology mean more tools for crime scene investigation. To take advantage of these advances, you have to be knowledgeable about the latest developments and about the capabilities of experts; you also need the right equipment.
This element is key to any health and safety program. When asked, most people on the street would say is this is what a safety program is all about.
There you are: too much to do, deadline looming, shorthanded, struggling to just keep your head above water…and now the boss wants you to take on a whole new project. It’s going to take lots of time, more time than you have. What to do? Delegate!
Do you ever stop to think about how you might be contaminating your equipment?

The proper storage of chemicals has become a focal point of laboratory safety. We need to keep chemicals which are incompatible separated some reasonable distance from each other.
Contamination is the unintentional introduction of outside DNA into a crime scene or laboratory sample. Contaminant DNA may appear as background DNA, the major or minor profile within a mixture, a single source DNA profile, or all of the above. Here are some common rules to help minimize contamination.
