I am trying to format the 64 kingston DataTraveller usb but i cant because it is write protected

try going to this link might be something very simple but they have good information. http://www.kingston.com/en/support/technical/products?model=DTHX30 could be a case of being a usb configuration problem

Connect it to a different computer.
Copy its files to the 'C:' drive.
Burn a copy of the files to a CD/DVD-writable disk.
Then "format" the device.
Copy the files back onto the device.
Use the CD/DVD disk on your computer.

Try re-formating the Pen Drive. Also check your USB and HUB drivers in Device Manager

2gb kingston pen drive showing capicity only 4 mb so pls provide the solution

Try formatting the drive. Should be a problem with the file system.

To slove your problem, Please see my explanation at this link http://www.fixya.com/support/r4391734-usb_flashdisk_pen_drive_write_protect

try this tool HP USB Disk Storage Format Tool!!

Did you read the emanual that is on the Kindston's website for the DataTraveller? When you use the password protection program, it logs you IN to another partition you created when you started it the first time. It logs you off of the  normal drive partition and in to the password protected partition.

Both exist on the same pen drive but can not be accessed at the same time. Try logging off using the same program or if there's such a logoff shortcut anywhere on the pendrive, yo should be back to the normal 2GB partition.

HTH,
Deboo
