I have a 4gig flash drive, which I can read from but not write on, erase, nor format in any computer (tried in 7 different computers including xp, vista, and win7).

I want to erase all the data inside because it is useless. Once I erase something, it erases it and gives me an error that it can't find the file. Once I refresh the folder, the file comes back. I tried holding Shift + Del. I also tried to use the command to format it in safe mode, but it says "access denied". I don't have a write protection button or whatever it is on my flash drive. It's just a simple small 4 gig one.

If the data might be useful to a criminal, break open the casing until you can see the memory chips. Use a hammer to drive a nail through the chips.

You can probably replace it for $5-$10. Don't spend too long trying to get it working.

The HP USB Disk Storage Format Tool is about the best at this kind of thing - if it can't work on the drive then it's possibly beyond help.

Try this :

1) Right click 'My computer' -> Manage or Management -> Disk management

2) select your USB drive -> Right click ->"change drive letter and paths"

3) Then Rename it to a different letter

Check whether it starts working or not !!

If it doesn't.. then options left are: 1) using diskpart 2) using registry 3) Low level formatting

Steps are lengthy and precise (must be done with accurcy) it is better to do it from here:
