Hi, this just recently happened to me as of yesterday and I really don't know what's happened. I've only had this external hard drive (WD My Passport 2 TB) for almost 4 months only (12/25/13-4/6/14) and its already not working. Let me provide you with some backstory:
I usually used this for school to use during the day as so: First period: plug in and at the end unplug using safely remove
2nd period: plug in and not unplug safely till 3rd period (kept it connected in between passing periods.
4th period: plug in and unplug at the end of the class
5th period: plug back in and unplug at the end of class and then I would leave it in my backpack sometimes after school. Each class was about 50 minutes, but never did I remove it without safely removing it first.
Yes, I have dropped this external hard drive. I dropped it about a week ago, but even up to the day after dropping and up until yesterday, it had been working perfectly. It was yesterday when something happened that I believe that might be the cause of this problem. I was at my girlfriends house yesterday and we were watching a movie on her laptop from this external drive in question and I paused it to get it up and go to the bathroom. When trying to get up, the external slipped as I was getting up and it almost fell off the cable but it didn't and just hung there, and I heard the disconnect sound but yet it wasn't disconnected. It was after thisis when it got weird. After returning from the bathroom, I unplugged and then plugged it back in, only this time it had a bit of trouble loading. After disconnecting and reconnecting (safely of course), I tried just copying it over to her desktop and it started and at about 20 percent, it started making a bit of a whirring noise louder than usual and the transfer rate just dropped to 0. There was no clicking at this time and after the whirring stopped I disconnected again and then reconnected and tried again and it worked just fine and made it all the way through. Once I came home, I ran CrystalDiskInfo and I found a caution about the Current Pending Sector Count (it being 200 of 200. I don't appear to have a screenshot even though I took one last night. I must've deleted it by accident.) After reading some forum posts online, I ran a WD diagnostic and it said it failed due to something about these sectors as well. (I'll try to provide a screenshot later)I went to bed last night around 4 AM and at that time it was still working okay and then when I woke up this morning, I find out to see it not in my computer anymore.
After seeing this, I began doing even more googling on this. I located both the disk in my disk management and my device manager, but no sight of it in My Computer or Explorer. In Disk Management I kept getting this pop-up about having to do something with it (I can't remember what) but I know no matter which choice I picked it said that there was something related with an I/O Error (I will also provide a screenshot later of this). I have tried this on 3 other computers other than my main desktop that I have here, and each time as of today it would begin to install the software as its working and it would sometimes have a clicking sound variating from 10-30 seconds in between each click and then sometimes as fast at 6-10 seconds. However, after it finished installing the software, the clicking would stop and it wouldn't come back even as we kept in there, but still no luck. (All of those computers were on Windows 7 and 8.)
I really have a lot of stuff on here that I would like to get back in any way possible. Even if I can't fully salvage the entire drive, if I can just get the stuff I want off of it, it would be a godsend. I just want to know after all of this if this external is entirely defunct and needs to be sent to the graveyard or if I can do something, anything to get this thing moving just enough for me to grab what I need.
Any help would be greatly appreciated. Cheers!
This is what I have done so far to try to fix it as well:
1. Tried different USB Ports
2. Tried uninstalling/updating the drivers
3. Tried going through Disk Management and seeing if I could change just the letter of the drive (that's where I got an I/O Error)
4. Tried going through CMD to change it from there but I could only find it by showing the disks
