I have a 16GB usb flash drive and I made it bootable to install Linux Mint. But for some reason, I couldn't install and did an unsafe eject.

Now, I cannot mount the drive, neither on Windows nor Linux.

If I run 'sudo fdisk -l /dev/sdb', following shows, 

Disk /dev/sdb: 16.0 GB, 16008609792 bytes
64 heads, 32 sectors/track, 15267 cylinders, total 31266816 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x4c66d349

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           0     1982463      991232   17  Hidden HPFS/NTFS

Is my flash drive dead? How can I make it work again?

Depending on what you want to do, you have a few options.

You can erase the content of the device and start again:

sudo mkfs.vfat -I /dev/sdb
sudo hdparm -z /dev/sdb
mkdir /tmp/x
sudo mount /dev/sdb /tmp/x

You can try checking the file system on /dev/sdb1, but based on comments from the op, it looks like it's a cdrom image, so it's read-only.

I have unmounted the failing disk /dev/sd[X] from its directory and run

sudo dd if=/dev/zero of=/dev/sd[X] bs=512 count=1

This filled it with binary zeros at a low level of formatting.

Then I could plug it in again and reformat it with GParted, starting again from the partition table and then with the file system of choice.
