Kingston 4GB Pendrive do not work any more.

When I insert my pendrive in Laptop or Desktop PC, it shows on in My Computer but when I try to open it, it says " Please insert disk into USB Drive". When I right click on the drive and want to format, it says there is no disk in the drive. When I go into Disk Management- it shows no media and Change Drive Letter and Eject are greyed out. Properties shows as 0 space.
Tried using third party Partitioning Softwares but they do not show the drive at all.
Also tried Diskpart to clean the drive but it shows- no disk.
Please help me repairing this pendrive. Please advise step by step method.
Thanking you in anticipation

Help with USB Boot Image

I am trying to boot from my USB flash drive. I followed the instructions step for step that are in the article on this website. I downloaded the HP program and the USB Image zip file. I ran the HP flash program and pointed it to the folder where I unzipped the USB Image files to. I then copied all the files over to the USB memory stick as instructed. When I restart my computer and press F12 to go to the boot menu I have 3 options: SATA hard drive, CD-ROM drive, or USB Device. So I choose USB device and when it reads the USB memory stick all I get is the error "Non-system disk, replace and hit any key" Its like the USB memory is missing some system files or it doesnt have the master boot record or something. Somebody please HELP!!! I want to flash the bios in a new video card and I have to boot to DOS and I dont have a floppy drive and I have Win XP so a USB boot is probably the best option I have.
