Haben Sie unzugängliche Daten auf einer Speicherkarte? Bei DataHelp spezialisieren wir uns auf die Datenrettung von verschiedenen Kartentypen, einschließlich MicroSD, Compact Flash und XQD. Unabhängig von der Art des Schadens oder dem Hersteller helfen Ihnen unsere Spezialisten, Ihre Daten wiederherzustellen.
At DataHelp we specialize in data recovery from MicroSD cards, as well as other types of SD cards. If your card stopped working, data is inaccessible or damaged, we offer professional data recovery from damaged memory cards. We work with a wide range of brands, such as Kingston, SanDisk, Samsung, ADATA, Transcend, Toshiba, Lexar, Sony and others.
Our services also include quick recovery of deleted data from memory cards used in digital cameras. In case of data loss, we recommend immediately turning off the device and not using the card further to prevent permanent data damage. Any DIY repair attempts can lead to irreversible data loss.
Our laboratory is equipped with top technologies that allow us to physically access damaged chips and reconstruct data even from the most complicated cases. Each card has its specific controller chip and memory blocks that require expert analysis.
We offer memory card diagnostics for €45 (European pickup included) and you only pay for recovered data. If you need data recovery from memory cards, contact us. We'll perform diagnostics and suggest the most suitable procedure for recovering your data.

Data recovery from memory cards is a complex process due to flash memory technology, which is prone to failures similar to USB drives, flash drives, or SSD drives. The most common cause of failure is controller chip malfunction, which contains the algorithm for data management in memory cells. This algorithm is key to proper data reconstruction, making the recovery process computationally intensive.
Besides chip failure, data recovery from memory cards is also complex due to limited memory cell lifespan, which have a set number of writes. A fundamental problem is data reconstruction from the entire memory media file, which requires large data space and laboratory technical equipment.
When recovering data from memory cards, it's essential that you cannot work with only part of the memory media – it's necessary to process its complete image. This means that for example with a 128 GB memory card, you need to work with the entire 128 GB file, which requires not only high computing power but also enough time for detailed analysis.
To effectively search and recover needed data, you must have data space that is many times larger than the card's capacity itself. This space allows safe processing and data reconstruction in full scope. If your memory card stopped working, it's likely a controller chip failure. In such case, it's necessary to use professional data recovery services that have top equipment for flash memory data reconstruction.
Die Abkürzung SD kommt vom englischen <strong>Secure Digital</strong>. Das SD-Format ist heute der am weitesten verbreitete Typ von Speicherkarten. Es existiert in mehreren Generationen und Größen, die sich in Kapazität und Geschwindigkeit unterscheiden.
MicroSD-Karten können mit einem Plastikadapter in Geräten mit Standard-SD-Kartensteckplatz verwendet werden.
Die Geschwindigkeit der SD-Karte ist besonders wichtig für Videoaufnahmen und Serienaufnahmen. Auf den Karten finden Sie verschiedene Markierungen, die die minimale Schreibgeschwindigkeit angeben.
Die Zahl im Kreis gibt die minimale Schreibgeschwindigkeit in MB/s an.
Ultra High Speed, die Zahl im U gibt Zehner von MB/s an.
UHS-I: max 104 MB/s, UHS-II: max 312 MB/s, UHS-III: max 624 MB/s
Für Video entwickelt, Zahl = Schreibgeschwindigkeit in MB/s.
Inside an SD card is flash memory – an array of cells that are individually rewritable. Digital information can be electrically programmed into individual memory blocks, which remains stored even without power.
Each memory cell's lifespan is limited – generally stated around 100,000 rewrite cycles. For even wear, a hardware layer called FTL (Flash Translation Layer) is present on the card, which ensures distribution of writes across all cells.
SD cards are not intended for long-term data archiving. During long-term inactivity (approximately 10 years), electrons can escape from memory cells and data can become unreadable. For archiving, we recommend regular backup to multiple media.
If the card reports an error, requests formatting, or photos are inaccessible, remove it from the device immediately. Further use or formatting attempts can irreversibly damage data.
Common data recovery programs can only help with deleted files. For hardware failures (faulty controller, damaged cells), they're ineffective and can make the situation worse. MicroSD cards with monolithic chips require specialized equipment.
Send us the memory card for diagnostics (€45 European pickup). We'll determine the type and extent of damage and tell you the chance of successful recovery and exact price. You only pay for successful data recovery.
