A pendrive Is...
Pendrive type devices or USB memories belong to the family of devices with FLASH technology. Its operation is very similar to SSD hard drives, but with both connection and internal differences.
The use of these devices was standardized with the appearance of the USB port, allowing information to be carried from one place to another in a very small space. Devices have evolved in terms of size, capacity and speed, both in Pendrive or USB type devices and in SSD hard drives.
Parts of a pendrive
Composed of a USB connector (in any of its A, B or C formats), the electronic board with various components, a controller and a memory block(s) to store the information. The operation is very similar to that of an SSD 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 FLASH MEMORY?
Except for SLCs, the rest of the technologies in FLASH devices such as Pendrives or SSD devices present common failures in terms of memory block degradation, causing the devices to stop working at any time. to function.
In many cases, the problems appear as follows:
- The computer does not recognize the USB stick.
- The USB flash drive is broken, damaged, or unreadable .
- The files or photos stored on the flash drive have been lost.
- Failed to read pendrive, the USB is unreadable.
- The pen drive or USB drive shows strange characters when connected to the computer.
- And faults of a physical nature such as breakage of the USB connector or damage in the controller of the block of memory due to short circuits.
Trust Laby, we can recover the information from your USB flash drive.
Flash technology has many advantages over traditional storage, but also some drawbacks. As mentioned above, one of them is the degradation of memory blocks. It is very practical to use pen drives or USB sticks as portable and fast storage from one place to another due to the mobility of everyday life.
However, we have become accustomed to working directly with them by opening documents, modifying them and saving them directly on the same device. This way of working causes the cells of the memory blocks to gradually degrade. In addition, the mere fact of being connected to the computer, without even using the USB, slowly depletes the cells as the operating system queries the USB device every X amount of time and the device responds.
To avoid degradation of the cells, the ideal would always be to connect the device, and when it is not needed, eject the operating system correctly to avoid wear and tear and/or loss of information due to incorrect disconnection.
This point is very important, since most USB flash drives 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.
Therefore, losing data if the device is not properly ejected may occur under these circumstances.

DATA RECOVERY PRICES FROM PENDRIVES, MEMORIES AND USB
The price to recover data from flash drives, memory sticks and USB sticks will always depend on the damage suffered by the device, together with the < b>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:
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.
NAND Flash memories are SLC, MLC, TLC and 3D NAND and for graphical representation we could identify it as a sponge cake, starting with SLC as a single layer and the rest adding multiple layers on top.
NAND SLC (single-level cell):
SLC (single-level cell) NAND offers higher durability than any other type, but very low capacity. They are the first flash devices. They could be considered “eternal” as 256 MB USB flash drives are still fully functional today.
NAND MLD (multilevel cells)
MLD (multi-level cell) NAND offers higher capacity than SLC NAND, however, its durability is lower and many USB flash drives started to fail after a short time of use due to the low fault tolerance of these types of memory.
NAND TLC (triple-level cell):
The NAND TLC (triple-level cell) offers higher capacity than a NAND MLD but at the cost of shorter lifetime. Due to the standardization of this technology, the manufacturing cost is lower. Most USB flash drives or USB devices are usually equipped with these memory chips, with a relatively balanced compromise between capacity, speed and cost.
3D NAND (vertically stacked cells)
3D NAND, (vertically stacked cells) are the latest evolution in the flash technology market.
Mainly used in SSD devices, they offer high performance and high reliability at a higher cost.
The set of memory blocks can be separate from the controller or embedded in the same chip. The price difference can vary depending on the controller and its encryption, the type of memory block and in other cases whether the wiring to access the memory block is known or has to be reverse engineered. In many cases, it is necessary to take X-ray images and use a signal analyzer to identify the individual signals in order to be able to read the memory block with the appropriate equipment. Once the reading process has been completed, the information will be extracted by carrying out the necessary processes, which may take several days of work.
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.
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 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.
Apple devices, both iPhone, iPad, iMac, MacBook, Mac Mini, etc. They are reliable, elegant, powerful and easy-to-use devices.
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.
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 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.
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 are used to store information from devices such as cameras, cell phones or tablets. They differ in their storage capacity and read/write speed.
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.
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.
We offer the service of deletion and destruction of secure data with a certificate, either in our laboratory or remotely.
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.
