Digital Media Data Recovery

digital-media-data-recovery_data-solutions-labsDigital media are represented by USB Flash and SSD memories and memory cards (SD, miniSD, microSD, CF, MMC, MC, MSD…)

Most of modern memories which are being used for storage of data are based on same or similar principle. Technology of almost all digital devices is very simple. There is always a memory chip which comes along with suitable controller and that’s basically everything when it comes to this storage device or memory.

Memory chip is practically a part of all types of memory cards, USB flash drives as well as other digital media which is based on NAND technology and usually are delivered in TSOP-48 case.

Data Solutions Laboratory was the first company in this part of the Europe that took part in data recovery from damaged digital media. Most of people consider this kind of data recovery almost impossible and we can say that this statement is correct only in case when memory chip is broken (crashed or burned). In most of the cases problem is related to controller responsible for writing the data to memory as well for reading. In that case there is almost 100% possibility for successful data recovery.

Approach used for reading or writing of data differ from one manufacturer to another and that’s what makes our job even harder. To put it simply, the logic goes like this. Controller is based on pre-defined algorithm for writing and reading of data. In order to complete data recovery with success we need to brake this algorithm. Implemented algorithm is based on protected logic, in other words it has been patented by manufacturer and it is not available to public.

Data stored in memory is organized in totally different manner than on hard disks. Memory has been divided to pages, size or logic for the particular page depends on type of the implemented algorithm. In addition the page layout in the memory itself is not based on linear logic so it can be several different variety or mix according to implemented algorithm.

For successful data recovery it is necessary to:

    • Unsolder memory chip from damaged printed circuit board
    • Read all sectors of memory chip and create image
    • Determine implemented algorithm
    • Clear away used mix
    • Compile all pages to one using proper algorithm

After suggested steps has been made, the data can be accessed in logical form according to file system. In almost all cases the FAT 12 file system has been used and we have to recreate tree of stored data. After logical structure has been successfully recreated, the data can be copied.

There are exceptions, of course. Mini or Micro SD cards have no controller installed and on the other hand there are some cases where devices use encrypted pages which cannot be decrypted in case of malfunction of installed controller.

Data Solutions Laboratory has a high success ratio in data recovery from all types of USB disks, which is over 90% and we are also recovering data from SSD drives by routine.

RAID Data Recovery

Data Solutions provides data recovery services from RAID and NAS (Network Attached Storage) server platforms. We posses top-level technology, expert knowledge and experience necessary for data recovery from RAID platforms. Data restoration services from RAID systems includes, but is not limited to RAID 0, 1, 5, 6 and 10 arrays.

Over the years we were able to recover valuable data from RAID arrays with one or more damaged hard drives. File and operating system type, amount of data, different kinds of malfunctions, or time frame do not represent an obstacle, only a challenge to our technicians. Usually, data recovery from RAID systems is treated as an urgent case.

Process is started by diagnosing what caused the system failure. As soon as we get separate medias able to access data zones, we copy all the sectors of every single media. After cloning the drives, our engineers will evaluate success rate of RAID reconstruction. During this procedure, we will complete media evaluation to determine is any damaged or malfunctioning drive.

The above mentioned analysis reveals any data errors and possible damage (bad blocks). Often, it is neccessary to repair so

me of the drives in array. During this procedure, in cases where the array is made of hard drives, and those drives have mechanical failures, we perform components swap inside disc casing, using our class 100 clean place.

In cases where there was multiple disc failure, we have to repair all the malfunctions. After we gain sector access, we create so called disk images, and then our technicians can begin reconstructing the array. More information about Data Recovery from hard disk drives.

In cases when RAID in question was made with SSD, we have to copy all the sectors from every single drive.

It is important to know that RAID systems usually arent protected from voltage surges or human error, which is the cause of malfunction in 50% of the cases. On the other side, the term RAID is short for redundant array of independent/inexpensive disks, so experience is needed in the configuration to provide long and stable workhours.

Although RAID configuration are usually associated with medium and large corporations, it should be pointed out that a large number of USB storages is delivered in RAID configuration. Even though they are comprised from two or four drives, data recovery from these media can be extremly demanding.

As RAID data recovery is a complex procedure which demands constant learning and skill perfection, technicians in our laboratory arecurrently learning to use new software-hardware solution. In a joint effort, our partners from Canada, Russia and China have perfected methods for data access after a RAID failure. This technological breakthrough will enable us not only to lower RAID data recovery time, but our prices as well.

Hard Drive Data Recovery

hard-disk-data-recovery-data-solutions-labsData Solutions Labs offers full range of data recovery services from all types of hard drives. As proven data recovery experts for the past ten years we managed to implement the highest level of success. We specialized in recovering data from damaged hard drives.

Our laboratory has a state-of-the-art technology and our experts are able to recover your crucial data from damaged hard drives from all manufacturers such as but not limited to: Seagate, Western Digital, Samsung, Hitachi or IBM, Maxtor, Toshiba, Fujitsu, Quantum and others. When it comes for recovering data from hard disk drives we are dealing with:

LOGICAL ERRORS

  • Deleted files
  • Viruses
  • File corruption
  • Partitioning errors
  • Re-formatting
  • Damaged File Systems

FIRMWARE ERRORS

  • Missing modules
  • Corrupted translator
  • Corrupted tables
  • Reading errors

PCB MALFUNCTION

  • Damaged chip
  • Damaged controler
  • ROM corruption
  • Over-heating

MECHANICAL MALFUNCTION

  • Head malfunction
  • Read/Write channel errors
  • Actuator problems
  • Damaged Media
  • HDA Chamber contamination

ACCIDENTS

  • Flood
  • Fire
  • Squall weather
  • Electric shock
  • Sabotage

Usually we are able to recover your data even in cases when most of other “professionals” marked your damaged media as unrecoverable and in most cases that is what we are successful.
