virus in your pendrive.
so format your pendrive dos command

start than run than type cmd than enter

ok and command type is

format (your pendrive colon) enter

i sure your pendrive format.

kya baat hai.........

Go to "My Computer", right click the Jetflash drive and click Format.
Select "FAT32" as the File System. Check "Quick Format" Click Start, and hope like hell there wasn't anything important on there.

if u still having the same problem, follow these steps:

1.Insert your pendrive. open mycomputer, note the respective drive showing pendrive.

2. Then go to run and type cmd ( or go to command prompt)

3.It will show like: C:\> or C:\Documents and Settings\UserName>

4.Type the drive name of pendrive as shown in e.g
if drive is h: then type as

c:\>h:
h:\>format h:
it will format and ask for media name, you can give the name of your pendrive.

your pen drive is formatted. Now it will show the free space as 8G.B

my transcend pen drive is not showing or hidden

opening pen drive, it shows 'please insert the disk' & it shows 0 bytes & while trying to format it shows the same message again , i am using 2 gb pendrive of trancend.
