Flash drive stopped working?

Question

USB flash drives

Good day!
I have a relatively new flash drive. Made it into a Linux boot disk. After I installed the OS, I removed the partitions from the flash drive and after that the flash drive died. It does not allow you to create a volume, assign a letter, format yourself. At any attempt to do something, the file is not found. How can I bring it back to life?

Answer 1

If it really does not allow you to do anything (even dd on dev / sdb does not work), then look at the VID / PID, find a service utility for the controller on usbdev and format it.

Answer 2

Made it into a Linux boot disk

It is not entirely clear what exactly you did - a full-fledged disk with the OS, from which you regularly booted and worked, or some kind of Emergency / Recovery CD, from which admins usually boot to work with machines that have some problems.
But that's not the point. It is possible (especially if they did the first one) that the flash drive could not withstand the volume of recording on it and ordered to live long.
If you have a Windows computer, you can diagnose the flash drive using R.tester . It's free and works without installation. If there is nothing important on the flash drive, then you can try, incl. write tests.

relatively new flash drive

However, if the drive is indeed under warranty, the best option is to exchange it under warranty.
Now the reliability of most flash drives is very low and you should not trust it with at least some significant files, even if the recovery attempt succeeds. The failure that has occurred is the best signal that the memory inside is unreliable.
