It is evident that there are many factors that may contribute to external hard drive failure. We have outlined only the most common occurrences. If your external hard drive is experiencing other symptoms, we are still able to help. We pride ourselves in our ability to recover data from any type of failure.

What To Do If Your External Hard Drive Has Failed
If you suspect that you are in need of External Hard Drive Data Recovery, taking certain precautions can dramatically increase the chances of a successful recovery. Continuing to power up a failing external hard drive can cause irreversible damage and may result in an unrecoverable hard drive. If your device shows symptoms of failure, discontinue use immediately.
Types of External Hard Drive Failures

Over time external hard drives are bound to fail. There are two main types of hard drive failures. The most common is a logical failure. The second type of failure is a mechanical or physical failure.

Logical Hard Drive Failure

The hard drive’s internal components are functional, but other complications make the data inaccessible. The integrity of the data is compromised and the stored data is damaged in some way. Common causes of logical hard drive failures include accidental formatting or deletion of files, corrupt or missing partitions, operating system errors, a corrupt file system, or a computer virus.

Mechanical Hard Drive Failure

Hard drives contain internal moving parts. When a mechanical or physical failure occurs, one or more of the internal components has malfunctioned. The drive may be experiencing difficulty spinning or, in some cases, it may not spin at all. This will result in data that cannot be accessed unless the drive is opened.  This requires a clean room environment where the hard drive can be rebuilt mechanically. Common causes of mechanical hard drive failures include head crashes, alignment issues, a broken motor, or spindle problems.

What to expect

The initial evaluation usually takes between 1 -3 business days depending on the extent of the damage. Upon completion of the evaluation, you will receive an exact quote for the recovery.  We will also provide you with the estimated time to completion and probable success rate. You can stop by anytime.  An appointment is not required.

Level 1 Data Recovery

Level one External Hard Drive Data Recovery is when your enclosed hard drive is working properly but there is other damage to the device.  This prevents you from accessing your data. For example, you spilled liquid on the external hard drive enclosure and it no longer turns on. As long as the enclosed drive wasn’t damaged by the liquid, this would qualify as a level one recovery.

Level one recoveries are usually completed within 2 business days. This often requires complete disassembly of your machine in order to gain access to the drive. Once the drive is removed, it will be tested to confirm that a level one recovery is possible. If so, we will transfer all of the data to either an external hard drive or to another computer. The more data there is on the drive, the longer the transfer will take.

Level 2 Data Recovery

Level two External Hard Drive Data Recovery is where about 80% of our clients fall.  In this case, the drive has started to fail but has not yet suffered a catastrophic failure. If the external hard drive powers on but does not mount, hangs, or flashes a folder icon then it may qualify for a level two recovery. However, not all drives with these symptoms will be recoverable using these techniques.

We are usually able to extract the data from the failing drives using specialized level two recovery tools. Failing drives are very delicate and must be handled properly. A level 2 recovery attempts to recover as much data as possible before the drive suffers a complete failure. Upon completion, you will be able to review the recovered data and confirm that it has been recovered to your complete satisfaction. If you are not satisfied, there is no charge for the attempt.

Level 3 Data Recovery

About 15% of our customers have no other option aside from a level three External Hard Drive Data Recovery. This is the last resort when dealing with severely damaged drives. It can also be used as a safer alternative to level two methods. At this level, the drive is sent into our clean room laboratory for extensive reconstructive work. The parts inside of a hard drive are incredibly delicate and can be easily destroyed with one wrong move.  These recoveries can be considered the equivalent to open heart surgery.  They are very complex and require great skill and precision.

Before files can be restored, the drive must be disassembled and repaired.  This must be done in a special environment in order to prevent damage to the data. A Class 100 clean room is necessary to safely complete a level 3 repair. Exact matching donor drives must be used to restore the patient drive.  Once the data can be read properly, the file system reconstruction can begin. Depending on the extent of the damage, we can often recover all or most of the data.

What is the price of the recovery based on?
Although many factors determine the cost of data recovery, it is based primarily on the level of damage to the hard drive.  Detailed reconstruction is often required to get the external hard drive back to a point where the data can be read properly. Once the drive has been rebuilt, successfully extracting the data is the easiest part! Whether its one file or a million files, the work required to get an external hard drive operational is the same. As such, the amount of data usually doesn’t affect the price.
