Usb flash drive (no media) - how to format?

17,016

The (no media) indication may mean that the flash memory is worn out: the flash memory controller built into the flash drive is detecting that the actual flash memory is no longer in usable condition, and it reports this to the computer in the same way a USB-connected CD-ROM drive would report that there is no disc in drive.

You would need special diagnostic software (probably available only from the flash memory controller manufacturer) to override the "no media" indication.

If you aren't a hardware hacker, throw it into trash. If it contained private data, put it into a plastic bag and then hit it with a hammer a few times first (the bag is there to contain the shrapnel).

    I'm using Kali Linux x64 2017. When I insert USB flash drive (16 GB) computer can't recognize it. I want to format it and erase all data. I've already tried on Windows and the problem is same (usb flash drive is not recognized). I suppose the problem started when I tried to create bootable usb with persistency and I accidentally changed filesystem to ext4.

    Is there any possible way to reformat it back to FAT32 or NTFS format? In Kali Linux, when I enter "Disks" see the pictures below: enter image description here

    It says "no media". When I click on settings, all options are gray except one (see picture below):

    enter image description here

    And the I enter "Edit mount options" (see picture below): enter image description here

    Is possible to retrieve USB flash drive to FAT32 or NTFS format? I don't need to keep data, I only want to format it to FAT32 or NTFS format?

    This is answer to @foobaru: The output is too long to put it here so I will post a link:
    For dmesg: https://pastebin.com/85wXCN3b
    For fdisk -l: https://pastebin.com/656mA7Dv

    When I try to reformat to FAT32 I can't find the device name: enter image description here

    what shoud I insert in the part where you said [yourUSB], because I don't know the name of the usb flash drive after I do fdisk -l. You can see the output of fdisk -l in this link: pastebin.com/656mA7Dv. P.S. The brand of usb flash drive is PNY 16 GB.
