pendrive not mounting

[biju philip]

Hi,

I installed ubuntu desktop 7.04 using bootable USB pendrive. when i login, i am not able to connect a new USB pendrive. i get the error message "cannot mount volume. invalid mount operation when attempting to mount the volume". in the browser window, i am able to see the name of the pendrive (jetflash). i tried to connect a USB hard disk also with the same error message. i tried to format the pen drive in windows machine as FAT, FAT32, NTFS. nothing worked. the USB port is working since i am using USB keyboard and mouse. Can anybody help me.

Biju
