Hi, anybody knows if it would work to replace the NAND chip from another U3? Does controller have ties to the NAND chip? My problem is that the flash drive full of info is dead. The LED blinks few times and PC doesn't recognize it as a USB device. Seems the controller is broken. If I take a new drive and replace the NAND chip, hopefully I'll see my data (unless San Disk implemented some security features here). Thanks!
