WHAT IS A MEMORY CARD?
Parts of a memory card
Memory cards (in any of its variants) belong to the family of devices with FLASH technology. Its operation is very similar to Pendrives or USB memories, but with differences in connection (due to the type and size of the card) although its internal part is not so much. The use of these devices became standardized with the appearance of cameras in the early 2000s and mobile phones.
Composed of a connector, the electronic board with various components, a controller and a block(s) of memory(s) where to store the information. The operation is very similar to that of USB devices or Pendrives, with certain peculiarities, but in general terms we could indicate that it is practically identical.
They come in various types and sizes along with different types of memory, although they could be separated into two types. Those that have the controller and memory block separately and those that are unified in a "single chip or tablet" called monolith.

PROBLEMS WITH A MEMORY CARD?
Except for SLC, the rest of the technologies in FLASH devices such as memory cards present common failures in terms of memory block degradation, causing the devices to stop working at any time. In many cases, the problems appear as follows:
- The computer does not recognize the memory card.
- The memory card is broken, damaged or unreadable.
- The files or photos saved on the memory card have been lost.
- Memory card read error, or is unreadable.
- The memory card shows strange characters when connected to the computer.
- And physical failures such as broken or bent pins or damage to the memory block controller due to short circuits.
Trust Laby, we can recover the information from your USB flash drive.
TIPS TO NOT LOSE DATA
Flash technology has many advantages over traditional storage, but also some drawbacks. As mentioned above, one of them is the degradation of memory blocks.
Today’s devices need large capacity and high speed to store photos and videos taken in high resolution. Today’s memory cards, thanks to new memory chips, allow high speed and capacity in a very small space. However, continuous use in mobile devices or memory cards can cause a sudden failure of these cards, either due to overheating or degradation of the memory blocks.
In addition, the vast majority of memory cards work in eXFAT (Extended FAT) format. It is a very old format, patched to be used today with large capacities (the original limit was 3.99 GB per file) but easily corruptible.
When disconnecting from cameras, cell phones or even the computer, it is necessary to correctly eject the device to avoid data loss.

HOW MUCH DOES A MEMORY CARD DATA RECOVERY COST?
MEMORY CARD DATA RECOVERY PRICES
The price to recover data from memory cards will always depend on the damage suffered by the card, together with the hours of work and technical equipment required to carry out the recovery processes.
In any case, a prior diagnosis is necessary to detect the type of failure or combination of various failures. Below we detail the most common breakdowns and the reference prices:
For SSD Firmware faults:
- SSD / FLASH electronics repair.
For physical faults (Controller / memory block):
- Unrecognizable devices, sudden failures, locked drives.
If we don't recover your data, we don't get paid
These prices are indicative, to be able to give you a reference.
If you want to know exactly the cost for you, it is best to contact us and we will give you a free estimate without obligation.
The process of data recovery from a memory card
The most common memory cards today are CF (Compac Flash in its evolution to SATA formats), SD memory cards and those of mobile phones and other devices such as MicroSD.
These cards present many of the casuistry of pen drives and their memory block failures (due to degradation and type of memory blocks) and also others of their own such as internal controller problems. On many occasions, controller temperature problems lead to breaks in the wires that connect to the memory block. These threads are very fine and susceptible to damage.
Recover MicroSD data
In order to carry out the recovery processes of these devices, there are several methods such as unsoldering the memory block in TSOP or BGA type memories (Photo). But in many other cases this process is not possible as in microSD where the controller and the memory block is encapsulated. In order to carry out the process of reading and extracting the data contained in the memory block, it is necessary to carry out micro-welding under a microscope, in order to directly access the memory block.
These welds, in many cases, the welding points are not known, so the signal analysis process must be carried out using a sniffer (software and hardware that allows the graphic representation of the electronic signals to be displayed on the screen and its subsequent interpretation)
Recover MicroSD data
Once the signal analysis process has been completed, the wiring must be soldered in the correct order and all the reverse engineering processes must be carried out to recover the information. It is a laborious and complex process in many cases, since it is necessary to emulate by software, the work that the controller does to save the information within the memory block: Determining the position of the information, the order of the sectors, discarding bad blocks , find the XOR or Scrambler keys and put the information back together to form a logical image.

WHAT DEVICES CAN WE RECOVER IN LABY LABORATORIES?
Mechanical hard disks
HDD disks have as main components the metal plates (disks), where the data is stored, and the heads that are responsible for accessing the information. The most common hard disk.
Vehicle Forensic Analysis
What is vehicle systems forensics? It is a process by which a wide range of data and information is extracted from vehicles, which can be used in collision and serious crime investigations. At Laby, we offer specialized services to support our clients in obtaining and analyzing vehicle data. Our team
SSD Hard Drives
SSDs do not move, hence the name solid state. The information is stored in blocks and no headers are required to access it. It is much more efficient and faster than an HDD hard disk.
External Hard Drives
External hard disks allow us to store outside the computer all the important information of which we want to make a backup copy. But one failure can cause us to lose all this data.
iPhone, iPad or MacBook
Apple devices, both iPhone, iPad, iMac, MacBook, Mac Mini, etc. They are reliable, elegant, powerful and easy-to-use devices.
Laptop hard disks
On the laptop hard disk we store important work or home information. If a failure occurs, it can cause us to lose all this valuable personal data.
NAS, SAN and DAS disks
A SAN, NAS or DAS disk is a compact enclosure consisting of several hard disks that are connected via a network cable to the system, hence the common name network hard disk.
RAID systems
RAID disks are a redundant group of independent disks. They can be HDD disks or SSD disks and together they form a storage system to distribute or replicate data.
Pendrives and USB Flash Drives
Pen drives or USB flash drives consist of one or more memory blocks. They work in many cases like SSD devices (same Flash technology).
Memory cards
Memory cards are used to store information from devices such as cameras, cell phones or tablets. They differ in their storage capacity and read/write speed.
Virus or Ransomware
We recover data encrypted with viruses or ransomware. Ransomware is extortion software: its purpose is to prevent you from using your device until you have paid a ransom. Depending on the type of ransomware, the entire operating system or just some files are encrypted.
Mobile Phones and Tablets
In mobile devices or smartphones or tablets, the recovery processes can be carried out through the analysis of the electronics of the damaged components or, by carrying out the chip off process.
Data deletion
We offer the service of deletion and destruction of secure data with a certificate, either in our laboratory or remotely.
Computer forensics
Computer forensic analysis and expert evidence. We recover and certify critical information with legal value for companies and individuals. We have collegiate computer experts to carry out certifications, expert analyzes and reports with legal value.
