Flash Drives help

Hello frnds i have a strange problem, i have a 4 GB Transcend and other 1 GB ordinary pen drives they used to work properly b4 but now they stopped showing up in my computer. Transcend is just 1 Month old and other drive(memorex) is 3 yrs old. I thougt there is some virus in my system and formatted my system, but no use and tried them in other system that too no use. If the problem is with pen drives then how cum with both, one is just 1 month old. Plz help me to solve this mystery :-o

 

Have you tried them on a rear USB port? Sometimes that works when the front USB port doesn't.

 

well my system has front USB but i donno how to connect it, there are strange connecters like ground+ and- and o on

 

Does your computer not have any USB ports on back?

 

The OP has been using the ports on the back because the front ones are not connected.

 

Well, if so, it seems to merely implied. I don't where he ever explicitly stated that, which is why I asked the question. Seemed like some clarification was needed.

 

I apologise if I misunderstood, but it appears to me that the OP was stating that he could not connect the front USB ports, therefore he was probably using the back ports.

 

This might help you- recoverymanager
it's also free

 

thanks for all ur help will try what u guys suggested, and also try recovery manager as suggested by voodoo3rd

 

it says no device connected and closed instantlly without any action

 

there are plenty of softwares in my 4 GB pen drive and i can't access it

 

If both USB devices do not show up in two different computers, (yours before and after a format as well as a completely different system) then I suspect there is something wrong with the USB drives.
