How to understand why the flash drive does not work?

Question

Iron

Hello! Why is the flash drive not working?
No program sees it. You can't format.
It is in disk management, but you can only change the letter, and that's it.
The computer is designated Removable Disk (J:) I poke it twice and writes "Please insert a disk."
I beg you to help, there is incredibly important data.

Answer 1

Very important data - prepare a lot of money and drag it to specialized offices.

Answer 2

See how it is displayed just above the disk management - in the device manager.
There are a lot of reasons, from a glitch with the driver and other software problems, to a dead or "buggy" controller.
Too few details.

Answer 3

I once contacted a special office with a similar problem.
The controller died in the flash drive. They opened it, unsoldered the flash memory chip, read it on the programmer, "decrypted" it with a special program, and burned it to another flash drive and CD.
4 hours of work and $ 200 money approximately - at the rate at that time.
Infa was worth it.

Answer 4

I am engaged in data recovery from flash drives and from experience I can say that with a high degree of probability we can say that there is a problem in the operation of the controller or firmware.
In general, you need to carry it to a special office and they will already do work there, as he wrote

The truth about 200 tanks is even a lot - if there is not a monolithic flash drive, but a flash drive with ordinary chips, then it is very expensive. In Kyiv, I do such work on average 40-60 tanks.
Although they may have taken it for urgency or just an expensive office
