Error opening in pendrive

when all the methods u know, to save ur pendrive, fails then only u should resort to this method. I have tried it myself and it worked very well.(If there is no physical damage)

For this u have to have a bootable CD eg......like Bootable Windows XP, 2000.

just plugin your pendrive and start the PC, Insert the Bootable CD, & press any key to boot it. (for this process first bootable device have to be selected as CD)

you will be entered into the OS installation process.

do the same process which you do while installing windows untill the CREATE PARTITION WIZARD comes.

in this u can see the Hard Disks of your PC along with the PENDRIVE's memory at the bottom.....................

u can easily recognise it from its memory (Like if u r using 2GB pendrive, it will show memory like 1952 MB)

select it.................. then press (D) to delete it, after deleting it press (C) to create a new partition of it
and give the full memory space which it take by default........................................

Its done............................................. just press F3 to quit from the installation process, remove the CD
and start the PC normally. & see your pendrive working accurately.

you should be very carefull while selecting the partition to delete coz otherwise u will loose your previous data of other drive.
