What it is and how a usb works

Posted by George on November 15th, 2019

USB flash is a data storage device that includes flash memory with a built-in Universal Serial Bus (USB) contact. USB flash drives are removable, rewritable and even smaller than a floppy disk.

A USB flash is often used to store, back-up, and transfer files to a computer. It is small, fast and durable and reliable because it has no moving parts.

USB flash drives supported by most modern operating systems such as Linux, Mac OS X, Windows, can also be read by other systems, such as Xbox 360, PlayStation 3, and some upcoming mobile smartphones.

The USB flash consists of a printed circuit with a controller, memory and USB connector, is electrically insulated and is usually protected in a plastic or metal case.

The estimated life of USB Flash can be measured by the number of recordings and deletions. USB flash can handle between 10,000 and 100,000 write / erase cycles depending on memory technology.

When the threshold is reached, some of the memory may not function properly, leading to data loss.

Of course, the life of USB flash can also expire prematurely if abused or left exposed in extreme conditions. In addition, if low quality memories are used, USB flash may cause damage much earlier.

High sensitivity to electrical discharges as well as problems connecting the device can cause frequent malfunctions.

It is very common in these devices for the controller to malfunction and subsequently make the data inaccessible.
Using specialized tools, DATARECALL manages to read the contents of memory chips using very specific techniques and technology.

Recovering data from USB Flash is a big challenge nowadays because it takes a lot of research to find out the standard used for these devices, but also because of the large number of manufacturers using their own standards.
