Very big problem please help me "

I have 2 flash memory 8 GB Cruzer you a simple connection device in the car and did not work and then no longer work even on computers, note that it was previously operated by the experience in the car and now is no lights and do not work I think that run in the car cause a problem
Now the question can you extract the evidence which in any way?

Can I send flashes to the company or go myself to the company

until it is repaired
Please reply

sounds like a dead device. if you need the data you would have to send it to a company that provides data recovery. here is a link to one.

I got the same problem, the flash drive was working just perfect for 10 days exactly, i was copying a divx movie, it finished the copy, then i put it onto Divx Portable Player, and it said that USB is not valid, then i return it my laptop, and GOSH!!  Unknown device pop ups every single time that i plug it into a usb port. Change laptop, the same, put it usb into car stereo, the same, not a valid usb. I’ve made it all, the power supply turn off solution, the uninstall from control panel, the update driver option, i refused to think that is a hardware problem, because it went from good to bad, in less than a minute. Thank you in advance for your help. I’m from México, english is not my native languaje.

Sounds like your DIVX Portable Player doesn’t work with FAT devices and screwed it up.  Or worst shorted it out.
