USB Device Not Recognized - Samsung 640GB disk data recovery

[maniera]

Hi,
I have a huge request for help in recovering data from an external drive Samsung S2 Portable 640GB.
From 2 Days browse the network and not found any solution that I can only order a company dealing with data recovery?
Hard work nicely 3 days in advance when copying 3 times I have rejected him
and there was an error not found the device, when plugged back to work and allowed me to re-copy the files to the situation there was maybe 4 times. 2 days ago when I connected the drive I got a message "USB Device Not Recognized" (a message appears on every computer I checked to 4).
The problem is that the drive is not getting in any way the DOS does not appear in the Disk management can not see it.
After hooking the blue LED lights up (when he was fit to the first light started flashing and after a moment shone permanently.) Do not receive any strange noises you hear that the dish is good.
ALL VERY PLEASE HELP!
ON DISK I do not care I just need to recover data

Sorry all for the poor language I hope the message is understood. I am writing here because the Polish forum got no help.

it is better to send this to someone who works on these drives. There is no ready solution for DIY and needs special tools in order to do this one. Try to find the person recommended to you.
