 i try also to format it from dos…is not working also when i try again with right clikc it’s saying ,windows was unable to complete the format,

The type of the file system is RAW.
The new file system is FAT.
Verifying 0M
Cannot determine the number of sectors on this volume.

someone might have formatted your clip on a MAC system…now if you want, you can format your device under PC but you have to go to dos windows to do this…to go to dos, press "Start > Run > type cmd & press Enter

And your device is already connected under MSC mode & you can see the device’s drive letter (i.e. G:)

in DOS, type in this command to format the device:  format G: /FS:FAT32 /A:32K & then press Enter…if this doesn’t work…then you have to go to a MAC and do DOS format.
