Data Recovery Flash Drive, Thumb Drive, Memory Card, SD Card
Thumb Drives, SD cards, Flash drives are computer gadgets that look like little disk drives to your computer. They are equal to thousands of floppy-disks and hold lots of valuable data like digital-camera pictures and documents. They have no moving parts because they store the data in NAND memory chips.
Why Flash Drives Need Data Recovery: Thumb drives often get broken off when users move their computers around. They can be damaged by simply pulling it out at the wrong time. Then the next time you use it, the card will appear to have 0 megabytes. NAND memory also wears out! Yes it actually erodes with use! To minimize the erosion problem the memory blocks are shuffled around. Flash cards are easily broken – the memory is just a sliver of glass – if it gets broken then forget it.
Data Recovery: One way to recover a NAND device is to fix it, resolder it – this is about 50% successful. Another way to recover the data is to read the data directly from the memory chips with a special NAND memory chip reader. This involves desoldering and removing the chips, reading their contents and then recombining them into an image of the original disk drive.
Alandata has successfully repaired and recovered many, many thumb drives and memory cards over the last few years. Alandata is one of only a few data recovery companies to have the technology to read the memory directly from the NAND memory chips.
To minimize problems with wear, the memory blocks are shuffled to different location. There are no manufacturing standards as to how the blocks are stored. There are no standard tables to map the memory. No standard makers or identifiers. All makers have their own scheme. There are literally thousands of possibilities. The challenge comes in determining the proper configuration – this takes experience, tools and expertise. Data Recovery Service – Alandata has all 3.
