Mechanical Failure Data Recovery

1) HARD DISK MECHANICAL STRUCTURE AND COMPONENTS

In a hard drive, there may be many types of mechanical faults such as head damage, spindle motor gets stuck, the head is stuck on the platter, etc. When such faults occur, a very low sound will come from the hard disk, to which we will have to listen very carefully. An experienced person can identify the mechanical fault inside the hard disk by listening to this sound. In this Physical Data Recovery Training, we will be learning about what happens when there is a mechanical fault in a hard disk and what might be its symptoms. Also, we will be learning on how to confirm the mechanical fault in the hard disk without opening the top cover using the sound detection method.

2) MECHANICAL FAILURE SYMPTOMS AND SOUND DETECTION

In the training session of Mechanical Data Recovery, we have discussed Hard Disk mechanical structure and components in detail. In this session, we will be learning about what happens, when there is a mechanical fault in a hard disk, and what might be its symptoms. Also, we will be learning how to confirm the mechanical fault, in the hard disk without opening the top cover, using the sound detection method.

3) INTRODUCTION TO MECHANICAL DATA RECOVERY TOOLS

We have read about the hard disk head, platter, and slider in the session of Mechanical Structure and Internal Component. The slider remains attached from the head, and the whole unit is mounted on the head arm. When the head gets damaged, In this case for data recovery, we have to replace the entire head assembly. If spindle motor in the hard disk gets stuck, then we have to loosen up the bearings engaged in that spindle motor. For such types of problems, we require the special tools for the mechanical data recovery. In this session, we will learn about different mechanical tools that are essential for data recovery.

4) DONOR HARD DISK SELECTION FOR HEAD REPLACEMENT

In the mechanical structure and components training session we saw that the structure of every hard disk is different. Some hard disks only have a single platter, while other hard disks might have two and three platters. A maximum of 2 heads can work on a platter. The preamplifier is also different in different models. When the hard disk head gets damaged, we have to replace that head with a working head to recover the data. Therefore, we need to select the donor hard disk for head replacement, which should be compatible with the damaged hard disk. In the training session of Mechanical Data Recovery, we will be discussing the donor hard disk selection criteria, to find the preface donor head for the head replacement.

5) HEAD STUCK PROBLEM SOLUTION PRACTICAL

Hello everyone. Many-a-times, the head of the hard disk will get stuck onto the platter while spinning down. It won’t shift into the head parking area. This problem is called head stuck problem. Whenever there’s an issue of the head getting stuck inside the hard disk, no rotation can be found in that hard disk. And sometimes, an unusual sound may come out of it.

In this session we will discuss how to identify head stuck problems, what are the symptoms, tools required for the head stuck solution, and how to solve head stuck problems with or without tools.
