In this article we will describe logical data recovery from a hard disk drive or other storage device in perfect physical conditions. If you suspect your storage device has any kind of physical damage - do not try to use any recovery or test software on it.

The goal of this article is to show you how a modern Hard Disk Drive or HDD is built. What are its main parts, how they look and what are these parts names and abbreviations. As an example we are going to disassemble 3.5" SATA drive.

This article shows how modern hard drives can read and write data. From this article you will learn about zones, tracks, sectors, servo system, variable density and some over stuff.

2020年4月12日 · What WD and HGST hard drives are SMR? May 4th 2020 in HDD Shingled Magnetic Recording (SMR) technology helps hard drive manufacturers to produce HDDs with larger capacity.

2020年4月19日 · The magnetic moment on a PMR HDD can be in one of two "pointing" states, so this can be used for recording binary information. An important part of MAMR is the Spin Torque Oscillator (STO). STO itself is located in close proximity to the recording head.

2020年4月12日 · It could be possible to make hard drives with density of 5Tbit per square inch just using HAMR (and this means 30TB 3.5" five-platter-drive). But technologies are evolving and manufacturers thinking about creating special bit patterned media which with HAMR reinforcement could hit 50Tbit per square inch record.
