When i have mounted some unix box's in my win xp machine using Magic disk it has created various drives according to my request. But when i insert my pen drive (JetFlash TS4GJFV30 USB Device) it shows in the system tray but when i open My computer i am not able to find the device.
I have done the following to get it back, (choose any one)
1. Search for JetFlash TS4GJFV30 USB Device in drivers.com and download the search result, install it then re-start.
2. Uninstall the Generic Volume from Device Manager (My computer->properties->Hardware->Device Manager)
Both worked for me :)
