5 Hard Drive Data Recovery Tips For Media Failure

External hard drives can fail in a number of ways. They may suffer from low power, motor failure, media failure or cable failure. This article deals purely with media failure, the most common problem that hard drives are likely to suffer from. This is when media blocks stored on the hard drive malfunction and the drive controller avoids using them. Here are five tips to help you if your hard drive suffers from media failure.

Tip #1. Identify The Problem

Media failure is the most common problem that hard drives are likely to suffer from. Your first task is to identify that your hard drive is suffering from this issue. Your hard drive may be suffering from a low power issue, motor failure or even cable failure. All four issues may cause a drive to fail to boot. If your drive un-mounts spontaneously or generates clicking noises, this indicates that media failure is not the sole cause and there are other factors at play.

Tip #2. Don’t Use File System Recovery If You Think There Is A Hardware Problem

You must proceed cautiously when attempting to recover data from an external hard drive. If there is an audible clicking sound and you believe that the hardware such as the disk or disk head may have an issue, you should not use a file system recovery program or recovery software. This may destroy your data and the hardware. There is the possibility that data on the hardware becomes unrecoverable even if you subsequently take the drive to a specialist data-recovery company.

Tip #3. Cool The Drive

Your hard drive’s hardware controller has an algorithm that looks at data in blocks and checks them against a forward error correction (FEC) checksum. The FEC is used to recover blocks that contain corrupted data. Data recovered in this way is rewritten in another location, thus causing the media failure error where the drive fails to read the data a number of times and the original signal is weak. Professional data recovery experts can acquire the data and reallocate the original block to fix the media failure. Therefore, your best chance of saving the data is to prevent your hard drive from overheating. You should cool your drive to preserve the data before taking it to a recovery specialist.

Tip #4. Back Up What You Can

If you can boot your drive and it operates without any issues, you can usually rule out head motor failure, low power or cable failure. If you have media failure, the best approach is to back up what you can. Secure the data you can access and leave the data that cannot be accessed.

Tip #5. Isolate Which Files Are Causing The Error And See A Specialist

The final tip for recovering data is to try to pinpoint where the media failure is occurring. Type ‘cat filename > /dev/null’ and monitor your console output or system log to see whether the data can be read successfully. The block data should be reallocated and the files should cause no further errors. If they do, you should visit a hard drive recovery expert in Edmonton.


Media failure is the more common hard drive error but problems during recovery can be catastrophic. The wrong approach can make the data unrecoverable so it may be best to consult a professional from the outset.

UK Spy Bill Worries Internet Users

The UK has finally released the first draft of its controversial Investigatory Powers Bill, a massive document that attempts to update and clarify what rights authorities have to access public data in the interest of combating crime.

The document’s main goal is to make the argument that since authorities already have the right to access information regarding that private phone calls people have made, it follows suit for them to also have the right to find out what websites and chat apps people use.

Accordingly, the bill proposes that authorities be able to bypass obtaining a warrant if they want to check people’s “internet connection records.”uk surveillance

They wouldn’t be able to see exactly what content was being made at whatever web addresses, but they would know what websites a person visited and at what time. For example, they could know if a person visited Instagram or Facebook, but not which specific web pages the person viewed or whether or not that person sent a message or left a comment.

They would access this information via network providers. The bill would require provider to maintain connection records for a year and then wipe those records clean immediately after a year has passed. Providers would need to create a log of IP addresses so that they can track and organize which devices participate in what activity.

Service providers aren’t crazy about the idea. Adrian Kennard, director of Bracknell-based internet provider Andrews & Arnold, had this to say:

“It is going to be costly and require a lot of equipment, but the big issue is that this is mass surveillance of the public.”

A warrant would remain necessary in the case of authorities wanting more specific browser history, such as which Facebook pages were looked at. Law enforcement officials would also be restricted in terms of determining whether someone had visited a medical website or mental health website. Even information about what news someone gets would necessitate a warrant.

“They would only be able to make a request for the purpose of determining whether someone had for example accessed a communications website, an illegal website or to resolve an IP address where it is necessary and proportionate to do so in the course of a specific investigation,” explained Home Secretary Theresa May.

Privacy-advocates take issue with the bill for a number of reasons. Not only are they disturbed by the push for such large-scale public surveillance by the government, but they’re afraid of the information being stored in the first place.

The bill would create files where data is stored regarding the pornography sites a person might visit, for example. Other examples of potentially sensitive browser history includes pirated media websites or political and religious sites.

If the information is being stored somewhere by service providers, realistically more than the government could potentially access it. Cryberattacks are on the rise, and cybercriminals tend to enjoy releasing private information to the embarrassment of their victims.ashley madison

Take the hack on Ashley Madison for example. Hackers stole information regarding members of the adultery-enabling dating website and threatened to release it if the website didn’t shut down completely. Ashley Madison didn’t comply, and the emails and personal information of its users were eventually released publically.

Most hacks aren’t so ethics-based, so just storing such sensitive information could put even honorable people at risk.
