Whenever a computer user cannot access the data on their hard drives, they look for solutions to resolve their problems. Unfortunately, some solutions may not be a clear-cut as others and they may need more information to take care of these issues. So, based on the circumstances or situation that the user experiences at that time, an expert may need to intervene. Specifically, when trying to determine if the user will need a process that involves either a physical or logical data recovery solution.
Having said this, what is the difference between a physical and a logical data recovery?
Physical Data Recovery :
A user will need the assistance of a physical data recovery solution when the actual physical or mechanical parts of a hard drive is adversely affected. For example, the data that the user needs is no longer available to be accessed when the physical hard drive or the solid state drive is no longer functional. This media can be affected in several different ways including the platter head crashes, the read and write capabilities have failed or the data is corrupted via SA Service Area.
Logical Data Recovery :
The logical data recovery does not involve the problems that the user experiences due to physical damage but consists of data being deleted inadvertently by the user themselves, a partition being corrupted or unable to be read due to a virus that is affecting the computer. Simply stated, no damage has been done to the physical part of the hard drive and it remains in good working condition. However, the files on the hard drive cannot be read because of its corruption.
To that end, the expert who recovers the data from the computer will need to determine the solution based on at least one of two recovery options, and they are physical data recovery or logical data recovery.
