I am kind of in a fix with my external HDD. My sister tried backing up quite a few movies together and I am not too sure what exactly happened. Its a WD 1TB HDD. I tried connecting it to different laptops and the issue is the same. The Hard Drive does not show up in my computers. It is there in the device manager and everything but I can't access the files and folders inside and neither can I put anything in. I can also eject the device from the task bar like any other USB device. I have a quite a lot of things in the hard drive and I am too scared to mess around randomly with it just in case. Could anyone please help me out?
Sorry to hear about the issues you're experiencing with your HDD. :\
Have you had any other problems with it before this happened? Any unusual sounds/noises coming from the drive, unusual transfer speed, freezing/hanging the system when you connect it? Did you use any specific program to backup the files or was it a simple copy - paste?
Would you be so kind as to post a screenshot of what you see in Disk Management when you have the drive connected to the computer?
I'd recommend that you try the HDD with a different USB cable (preferably not longer than 12"-18") as well, to see if the issue still persists.
