usb - How to fix my pen drive?

I have a Toshiba Pen Drive.

Whenever I plug it to a computer, it shows a message saying-

You need to format the drive before you can use it.

I have tried repairing it via the command prompt way as listed in this site:

How to repair Pen Drive

Diskpart>List Disk> Select Disk 2>Clean

But again the computer returns an error during the 'Clean' command. It says that the action cannot be completed because of an I/O error.

I have tried using Acronis Disk Director to create a partition in the pen drive and recover it but to no avail.

I have tried using a software called Find and Mount to recover a partition but again to no avail.

I tried using google. Cannot seem to find any other way. Please help!!

Really sounds like that drive is toast. If you can't format it with a utility like the HP USB Disk Storage Format Tool then it's likely to not be repairable.

Here is the link to the format tool however I don't think it will do any good if diskpart is failing to fix things.
