Inside the plastic casing is a small printed circuit board, which has some power circuitry and a small number of surface-mounted integrated circuits ICs. Drives typically use the USB mass storage device class to communicate with the host. These had limited capacity, were slow for both reading and writing, required complex high-voltage drive circuitry, and could be re-written only after erasing the entire contents of the chip. Hardware designers later developed EEPROMs with the erasure region broken up into smaller "fields" that could be erased individually without affecting the others. Altering the contents of a particular memory location involved copying the entire field into an off-chip buffer memory, erasing the field, modifying the data as required in the buffer, and re-writing it into the same field.
Is there any way to fix USB flash drive not detected and restore the data. I have all my school work on it. Please help if you know any solutions. No matter for what reason except for physical damage , you can try EaseUS file recovery software to restore your data and then repair the device by formatting for reuse. It is the easiest and most popular way to fix USB flash drive not recognized error without losing data.
How to Repair & Recover USB Flash Drive not Recognized or Detected
When something like this happens, is it possible to fix a physically broken USB drive? Photo courtesy of Joel Poxton Flickr. My friend just wrote to me, all panicked, that he had broken his USB drive with his math homework for tomorrow on it.
