It's not visible in the explorer, though, and recovery software like Kroll OnTrack does see it as some 'unrecognized drive' but can't start recovery because neither its Scan or Deep Scan features find any partitions. When you plug it in, the PC does recognize it in some way, though, because you can hear the sound of a new USB device being connected and see it listed as a USB device (WD Hard Drive) in the system tray. After that, it becomes pretty silent or makes its regular, pretty quiet shuffling sound (though the LED keeps blinking all the time). When you connect it to a PC, the white LED keeps blinking all the time and for a minute or so, the disk makes an intermittent clicking noise. So I restarted my PC and after that, the drive didn't work anymore. I thought nothing of it, retried a few times - nothing. I have WD Passport external HDD and yesterday, when I was transferring some photos to it, the transfer suddenly stopped.
