No, you can’t put a platter with a different size in a hard disk. Laptop and desktop HDDs are built differently, and their read/write heads work differently.

What do hard drive platters do?

A hard disk drive platter (or disk) is the circular disk on which magnetic data is stored in a hard disk drive. A platter can store information on both sides, requiring two heads per platter.

What is the purpose of a read write head?

A read/write head is a specific physical part of a hard disk that is responsible for reading data from, and writing data to, the disk. Read/write heads are typically made up of a thin horizontal magnetic blade attached to an actuator arm.

What is spindle in hard disk?

A spindle is a shaft that holds rotating hard disk drive (HDD) platters in place. The term is also often used to refer to a single HDD. Spindle speed, measured in rotations per minute (RPM), is one metric used to gauge disk drive performance.

What is Platter swap?

This includes securing the platters (and dampers for some models), replacing the head assembly, ramp, filter, cover and the PCB (Or using the donor PCB with ROM swap in some cases).

How many read/write heads does a mechanical hard drive have?

There are two read-write heads for each platter, one to read the top surface and one to read the bottom, so a hard drive that has five platters (say) would need ten separate read-write heads.

What sits between the head and the platter of a disk drive?

In modern hard drives, the amount of space between the head and rotating platter at normal operating speed is typically less than 5 nanometers… this gap is also referred to as the flying height. This actuator arm moves back and forth allowing the heads to sweep across the platter surface to their required location.

How many platters are in a hard drive?

A typical consumer hard drive may have anywhere from one to five platters. The weight of the drive is often a good indicator of the number of platters used. Most new desktop hard drives with 1 TB or lower capacity have only one platter to reduce cost.

What happens if the platter alignment is lost?

The amount of data each platter holds and the mapping of the heads varies from model to model. Maintaining the alignment between the platters is crucial. Data will probably be inaccessible, and may be unrecoverable, if the platter alignment is lost.

What is a disk alignment tool and how does it work?

This is a vital tool, which allows the removal of all the platters simultaneously whilst maintaining their alignment. The tool allows transplantation of platters from a failed drive to a working one, thus facilitating data recovery.

What is a hard disk platter?

A hard disk platter is a component within a mass storage device, which stores the binary data within ferromagnetic grains layered on its surface. The data is stored within the layers using a principle called perpendicular / vertical recording.

Can hard drive platters be swapped one by one?

Within data recovery field, maybe only 5% believe that hard drive platters can be swapped one by one and most of them believe after removing the platters one by one, the platter alignment issue is generated and no data recovery is possible.
