Read our article on the types of hard drives to learn more. Note: There are several ways to categorize hard drives based on their storage media, data transfer interface, form-factor (size & shape), speed, purpose, storage capacity, etc.

However, they can malfunction or stop working due to firmware corruption, which is a complicated situation. An SSD can tolerate physical shocks and run silently because there are no mechanical components and movement. The firmware is responsible for bad block mapping, read/write operations, garbage collection, wear leveling, etc.
HARD DRIVE DATA RECOVERY TOOLS CODE
Solid-state drives have a memory controller that runs a firmware-level code (similar to an OS in a PC) to connect the memory to the host computer.

Flash memory is an electronic storage medium that allows faster reading (retrieval) of data. SSDs lack moving mechanical parts and use flash memory and an integrated circuit to store the data. This vulnerability is due to their use of moving components that need to operate with high precision. Notably, HDDs are susceptible to damage or malfunctioning due to physical impact. Uniform spindle speed, specific clearance between the head and platter, integrity of the magnetic coating are some of the “physical” aspects that are key to the long-term data storage and retrieval on hard disk drives. A platter can store data on both sides and is paired with a magnetic head attached to an actuator arm that glides over the platter surface at an ultra-low clearance to read (retrieve) and write (store) the data. It comprises one or multiple platters – circular disk with magnetic coating – mounted on a spindle. The HDD is an electromechanical data storage device that relies on magnetic storage. This section emphasizes the HDD and SSD categorization for the drives as knowing the basics of the “storage media & make” will help you troubleshoot the root cause of data loss and choose the right solution. There are two types of hard drives based on the storage media & technology *, namely What are the different types of hard drives?īefore we deep-dive into hard drive recovery - scenarios & solutions, etc., let’s understand the types of hard drives because that would equip you with the necessary background knowledge. The following section outlines the types of hard drives based on the storage media and technology. Nonetheless, be aware that these hard drives face similar levels & types of risks that could lead to a “permanent” data loss.
HARD DRIVE DATA RECOVERY TOOLS PC
You might be using these drives as a USB (external) storage externally attached to your MacBook or Windows PC or built-in storage inside the system. that could jeopardize the data stored on a hard drive by hard drives, we mean Hard Disk Drive (HDD) and Solid State Drive (SSD). There are other significant reasons such as formatting, corruption, lost partition, malware infection, physical damage, etc. Accidental deletion is knowingly the biggest reason for the loss of files from a hard drive. You know there could be reasons like accidentally pressing the SHIFT + DEL keys on Windows or Option + Command + Delete on MBP and Poof! Your data is gone forever, and the situation turns panicky.
