HARD DISK DRIVE DATA RECOVERY

Data Engineers have been providing hard drive recovery services from faulty and broken hard disk drives since 2010, and are the India’s #1 hard drive data recovery company. Our success rates are exceptional.

We are so confident that we can recover your data that we offer a ‘No Data – No Fee‘ service in most cases. Please do not open your hard drive yourself, as this will negate this service.

MAIN CAUSES OF HARD DISK DRIVE FAILURE

1. MECHANICAL

Failure Symptoms:
– The hard drive may make a regular clicking noise when it is first powered on. This will last for approximately 20 seconds before the disk powers down.
– The hard drive may beep when first powered on.
– The drive will not be recognized by the computer
– Listen to an audio file of a hard disk drive with a mechanical fault

Causes:
– The hard drive has received a knock: for example, it may have been dropped, or if it is in a laptop, the laptop may have received a bang.
– Mechanical failure is not exclusive to hard drives receiving knocks, hard drives can fail at any time – especially the older they get.

2. LOGICAL

Failure Symptoms:
– Files and Folders will not open or have become inaccessible
– Files and Folders will not copy correctly – often CRC (Cyclical Redundancy Check) errors will be reported
– Files and Folders may have been deleted or overwritten

Causes:
– Areas of the hard drive may not be readable due to the development of bad sectors.
– Data structures on the hard drive may have been corrupted due to (e.g.) the disk not being ejected from the system correctly.

3. ELECTRONIC

Failure Symptoms:
– The drive will not spin when it is powered on.
– Sometimes the hard drive will get very hot.
– It will not be recognized by the computer.

Causes:
– A power surge has caused damage to the drive
– The wrong power cable has been plugged in.

4. FIRMWARE

Failure Symptoms:
– The drive will be recognized incorrectly by the computer
– Often the capacity of the drive is also reported incorrectly

Causes:
– The firmware (or ‘microcode’) that runs the drive has become corrupted. Often this is a result of software bugs that exist in the firmware.

Our hard drive recovery services are safe and secure; so you can be completely assured that our processes are designed to protect your data and your privacy at all times. We are registered and monitored by the Central Information Commission.

If your data is particularly sensitive or valuable, then we can provide extra security measures through Non-Disclosure Agreements, encryption, and security cleared couriers, if required.

Open Pricing Policy

Data Engineers operate an open pricing policy and we will give you the data recovery cost before we commence the recovery process. When you call us on +91-9818567981, or fill in the contact form, we will give you a quote. If you are happy with the quote, then we will arrange a courier to collect your hard drive from your home or business. Once we have fully diagnosed your hard drive disk failure, we will provide you with the full cost to go ahead and recover your data to a new hard drive and return it to you by courier service. If you do not wish to go ahead, we simply return your hard drive.

Few Of The Problems

After the failure, interventions and handling of the disk by uninformed users can prove fatal to the data. Rather than recovering your data, these ill-advised attempts could hinder the recovery and irrevocably lose the data. After an accident that causes the hard drive to fail, some people call in technicians with little or no qualification.

We support almost all types of drives: SATA, IDE, SCSI, SAS, SSD, disk grouping in RAID etc.. We also support most storage media.

It is strongly recommended to consult a specialist before taking any action. We have had to deal with disks that have undergone interventions that made the data unrecoverable for good. Hard Drives are sensitive and very fragile equipment, an expertise is necessary to be able to handle them.

Data Engineers has the necessary equipment and know-how to perform physical data recovery. Our laboratory provides the necessary conditions for opening the discs and replacing the different parts that make it up.

We ensure total traceability and confidentiality of all documents and media that reach us, from their delivery in person until their return to the customer. Our systems comply with the latest security standards (surveillance cameras, secure equipment, user rights). In addition, each employee must sign a confidentiality agreement before being recruited by Data Engineers. Our security extends even to the software level: all our devices are secured by software and by access rights. Finally, our premises are guarded 24/7.

Mobile Phone & Tablet Data Recovery

The phrase ‘mobile phone’ is still commonly used to describe a modern mobile device such as a smartphone, tablet computer, PDA or GPS device, but these days mobile devices are more like powerful handheld computers with capabilities that far exceed that of a simple mobile phone. Similarly the phrase ‘mobile phone repair’ and ‘mobile phone recovery’ therefore also apply to smartphones, tablets and other mobile computing devices.

The smartphones that many of us carry in our pockets hold a huge amount of personal data such as contacts, photos, calendars, notes, SMS and MMS messages, video, email, web browsing information, location information, social networking messages and contacts. Damage to these devices can cause loss of data but this data can nearly always be recovered – even if it’s been deleted, either accidentally or on purpose. Sometimes a device may be so damaged that it no longer switches on, it may have been dropped onto a hard surface or into water, and for many mobile phone repair companies recovering the data from a broken mobile phone in this condition is a step too far. Fortunately we are able to go much further than the services offered by most mobile phone repair companies and can extract your data directly from the chips that store it on your mobile phone and recover the files you are looking for.

Successfully recovering all the data from a mobile device is a specialized skill quite different to that of recovering files and folders from a home computer. Most mobile devices don’t share the same operating systems and are proprietary embedded devices which have unique layouts, memory and hardware configurations.

Data Engineers are able to recover data from all types of mobile device including:

  • Smartphones (all makes, including iPhone, Samsung, LG, HTC, Nokia, Sony, Motorola, Lumia, Xiaomi Redmi, Etc..)
  • Tablets (all makes, including HTC, Lenovo, Linx, nVidia, Acer, Samsung, Sony, Apple, Asus, Kindle, Etc..)
  • Bricked devices
  • Phones not showing up 
  • Apple, Android, Windows, SatNav, Memory Card and SIM devices
  • Associated external memory- SD, MicroSD, MMC etc
  • Portable GPS devices
  • Phones manufactured with Chinese chipsets
  • 3G Modems
  • Portable music players, iPods, MP3 players etc..

The type of data we can extract includes:

  • Handset information and SIM-card data
  • Contact information
  • Incoming/Outgoing/Missed Call Logs
  • SMS and MMS messages & timestamps (including deleted messages)
  • Email
  • Data from Apps (WhatsApp, Telegram, Facebook, Tango and chat data from many other messaging applications)
  • Calendar events schedule
  • Tasks
  • Text notes
  • Photos (live and deleted)
  • Videos (live and deleted)
  • Audio (including answering machine messages, voice-notes and messaging app audio messages)
  • Documents & Other Files
  • Full file system from phone memory and flash cards
  • GPRS and Wi-Fi activity giving locations (‘cell site analysis’)

In most cases we are able to recover all the available data stored in a device. Typically this is performed by bypassing the operating system and this offers us the opportunity to go deeper and recover deleted data from the device.

This is separated out into two distinct stages, the initial ‘Dump’ whereby the raw data is recovered from the device and then the second stage ‘Decode’ – where we reconstruct the data into something meaningful & useful for the customer.

We present the data extracted in a clear and meaningful way, so you can quickly and easily understand and identify what data is of interest.

Involved in a legal case ?

Do you need data from your phone extracting forensically so the evidence on it is admissible in court? Read more about our forensic investigation (eDiscovery) services, and more about the advanced forensic data recovery techniques we have at our disposal to retrieve the data from badly damaged Mobile Phones, Tablets & Digital Media. We recover data where others have failed.

Our Advantage

Data Engineers use multiple cutting edge methods for extracting data from mobile/smart phones and tablets, including the most widely used forensically sound solutions used by law enforcement and some that they don’t, due to lack of training and/or resources. These advanced methods allow us access to the data on handsets others cannot reach – For example PIN locked devices, Stuck on boot loop or those that are inoperable due to Physical damage.

SSD (SOLID STATE DRIVE) DATA RECOVERY

SSD’s or Solid State Drives to give them their full title are relatively new devices that store computer data in non-volatile memory chips and contain no moving parts – simply imagine a memory stick that plugs into your computer’s USB port but with a much larger storage capacity and you have in essence what an SSD actually is.

SSD’s are very different to their conventional hard disk drive (HDD) counterparts that use magnetically coated rotating platters to hold data. Compared to hard drives, SSDs are typically less prone to physical damage and are far more resilient. It’s important to note however, that this does not mean they are indestructible. SSD’s still fail at rates similar to HDD’s. but in different ways.

MAIN CAUSES OF SSD FAILURE

Loss of data on SSD’s can be due to a variety of reasons and some common types of SSD failure include:

– Damage to the drive’s firmware zone
– The SSD is no longer recognised
– Electronic faults
– Physical damage
– Service Area corruption
– Damaged controller
– Logical data corruption
– Accidental deletion of files and folders

As discussed above, SSD hard drives fail just like their HDD counterparts but in different ways. Whereas HDD hard drives will often fail with a problem related to their moving mechanical parts, SSD’s usually fail with problems:

– Buggy Microprogramming
– With Electronic Issues
– With Data or File System corruption

SSD Data Recovery is possible and but is highly specialized. We recommend sending the drive to us as we have a good success rate with SSD’s, but of course it’s on a case by case basis and we would need to diagnose the exact problem with your hard drive before knowing whether a recovery of data is possible.

Few SSD Manufacturer produced SSD drives which had bugs in it’s microprogramming causing it to hibernate in certain circumstances. It was not possible to wake the drive from hibernation – and to this day there is no data recovery fix for this problem.

Pen Drive & Memory Card Data Recovery

At Data Engineers we use hardware data recovery techniques to retrieve the files from damaged Pen Drives & Memory cards. These methods are far superior to any software approach – a software program can only do so much as it is controlled by the computer’s operating system which will prohibit and limit certain actions. Using a hardware based data recovery approach means that we have no such limitations.

1. Types of Pen Drive:

  • Normal USB Pen Drives
  • Micro USB Pen Drives
  • Type-C Pen Drives

2. Types of Memory Card:

  • SD Card
  • Micro SD Card
  • Compact Flash (CF) Card
  • Memory Stick Or PCMCIA Cards

MAIN CAUSES OF PEN DRIVE & MEMORY CARD FAILURE

Pen Drives & Memory Cards can have logical, mechanical, and physical failures. Since most failure scenarios present similar symptoms, diagnosing the precise cause of data loss requires careful analysis and patience. We have the expertise to repair and retrieve data in challenging situations, including:

  • Broken Connections
  • Defective or Snapped Electronics
  • Excessive Use
  • Accidental Deletion or Formatting
  • File Corruption
  • Virus Damage

Disconnect your flash drive to protect yourself from permanent data loss. Do not attempt to fix the device yourself if the data is valuable.

Our Pen Drive & Memory Card recovery services are safe and secure; so you can be completely assured that our processes are designed to protect your data and your privacy at all times. We are registered and monitored by the Central Information Commission.

If your data is particularly sensitive or valuable, then we can provide extra security measures through Non-Disclosure Agreements, encryption, and security cleared couriers, if required.

Frequently Asked Questions

Yes, you can recover data from a dead pen drive or memory card by taking the help of reliable data recovery services. At Data Engineers, our data recovery experts can recover the data from the dead pen drive with 100% privacy.

Your Pen Drive or Memory Card can be severely damaged due to physical water damage, short circuits as well as bad blocks, failed firmware updates and malware corruption.

Yes, it is possible to recover data from a Pen Drive or Memory Card. Even if it becomes inaccessible or formatted, the stored data is not lost forever. Our data recovery experts can access and retrieve the files from the device.

Most of the damaged device can be recovered if you act quickly. Professional data recovery software or services can usually retrieve lost files, but you need to stop using the device immediately to prevent overwriting any data. Continuing to use the device could result in overwriting your lost files, which would make them unrecoverable. Contact our qualified data recovery team to explore your available options.

DVR & NVR CCTV Footage Data Recovery

Data Engineers are the India’s Number One company for recovering your DVR / NVR and CCTV data. If you have CCTV data recorded on a DVR or NVR system that you can no longer view, maybe because the system won’t play the footage back, or it’s been deleted, or the recorder and hard drives have been damaged: as long as the data still exists Data Engineers can retrieve it.

Our CCTV data recovery services have been useful to many companies that rely on their security equipment to provide 24/7 security of their premises.

The successful identification of a criminal and their resulting prosecution means that our CCTV recovery and enhancement procedures are highly valued by many organisations, both commercial and public that are keen to reduce crime and protect people and property.

Why CCTV Footage Recovery is Required?

CCTV is also increasingly used in the workplace to monitor safety and other related issues such as compliance to health and safety standards. If there’s been an accident or incident at work, the HSE (Health and Safety Executive) will usually request evidence of the incident on CCTV. Additionally they will want to examine the entire recorded footage to ensure safety compliance is being met.

Data Engineers are frequently asked to recover information from workplace CCTV DVR and NVR systems that show accidents and confirm compliance or non-compliance to safety standards.

If recorded incidents are to go to court, additional procedures have to be followed that ensure the evidence is admissible.

CCTV Footage For Criminal Cases

CCTV has become a widespread weapon against crime; its very presence is a deterrent to people who are looking for opportunity, opportunity with a criminal motive. Often petty criminals will simply go elsewhere if they think there is video surveillance. That is not always the case of course and the provision of CCTV evidence in identifying a crime and finding a culprit has become an important tool for police and the judicial system.

Data Engineers can recover the information from CCTV DVRs and NVRs involved in criminal cases. Furthermore if the recorded incident is intended to be used in court, chain of custody procedures will need to be followed to ensure the retrieved video evidence is admissible. Please contact us for further details.

Recording CCTV Footage To DVR / NVR Device

DVRs and NVRs operate by recording CCTV data on to hard drives and can be viewed with date and time details. Some monitoring is done on a much smaller scale; perhaps a PC which provides security for a room. Their encoding systems varies on different platforms such as Linux, Microsoft, etc..

The technique of CCTV Data Recovery is the same as that used for all hard disk data retrieval. DVRs and NVRs have the same problems as any other device that uses a hard disk and our research and development department has ensured that we lead the field in data retrieval from hard disks in hardware and CCTV.

Securing CCTV Data – Beware of overwriting Nearly all CCTV systems record their data on a continuous loop. Once the end of the loop is reached, the system will start to overwrite the oldest data. The length of the loop is usually a figure in days. For example a CCTV system with a 21 day overwriting cycle will only store the last 21 days of data. Anything older that this date will have been overwritten by fresher data. So, if an incident occurred 24 days ago, this data will have already been overwritten and there is no chance of recovering it. Therefore it is important to secure data from a CCTV system before it is overwritten.

There are majorly three types of hard drive failures: physical, logical & logical cum physical

To diagnose a physical hard drive failure, look for signs such as the computer not detecting the hard drive, the drive not spinning, or an abnormal noise coming from the drive.

To diagnose a logical hard drive failure (which is a non-physical issue), look for signs such as accidental data deletion, Partition corruption, partition deletion, format, reinstall, and virus attack. etc.

To diagnose a logical cum physical hard drive failure look for signs such as firmware issues, bad sector, or weak head in the hard drive.

Below-mentioned are the symptoms of failed hard disk:
• The system makes strange noises (whirring, clicking sounds)
• Overheating of your Computer
• Corruption of Data, Files, or Folders
• Receiving frequent error messages on screen
• System’s failure to boot
• No response to commands
• Hard disk is undetectable or not recognized by the system
• The system does not detect or recognize the hard drive
• There is an issue with the hard drive not being detected by the system BIOS
• No spinning of Hard Drive
• Showing error message – “Blue Screen of Death”
• Increase in Bad Sectors
• Majorly slowdown of CPU
• Blank Screen

Physical failures – This is due to any physical damage such as burning/dropping of the hard drive. Some symptoms include:

  • No detection of the hard drive by the system
  • Drive does not spin
  • Drive heats up excessively
  • Unusual ticking sounds while data is being read by the hard drive
  • Grinding/clicking noise

Physical damage can be ascertained quite easily. You should refrain from attempting to open the HDD all by yourself since this increases the chances of damage. Get the situation rectified by experts.

 

Logical Failures – This occurs in case of human errors, malware/software infections, corrupted failures and also in case the hard disk does not boot properly. Some symptoms include:

  • Bad platter/media
  • Hard disk recognized by BIOS but data cannot be accessed
  • Corruption of data from other file sources
  • Human errors such as changing of file attributes or registry file modifications

Fixing these failures does not require opening up the HDD and recovery software and tools can be used by Data Engineers for getting back your inaccessible data. We can help you fix this problem with ease.

 

Mechanical/Electric Failures – These failures are usually linked to HDD components. Some symptoms include the following:
  • Crash of hard disk head/heads
  • Magnetic platter damages
  • Failure of hard drive motor
  • Damages to PCB
These failures usually mean that higher time and effort is required to recover data and you should immediately contact Techchef experts for the best solution.
