2TB WD Ext Hard Drive: From Lag to unrecognizable

[JonnyWisco]

I've had my 2TB WD external hard drive for about 6 months now with no problems whatsoever, until now. I had to take my laptop apart to fix the keyboard, which entailed me taking out the disk drive. So I got everything back together, it seems the disk drive is resetting or whatever, but my WD drive is lagging like crazy. When this first started the drive showed up and I could access and watch the video I have in the first set of folders, but when I went to the subfolders it just lagged and became unresponsive. I figured that it just had to go through and recognize the files and so I left it overnight. Today I checked it out and I could again access the video and it would go to the first subfolder but when I tried to access another subfolder it again became unresponsive. Then after unplugging it and restarting a few times my laptop wouldn't recognize the drive. It did say there was something there but not the usual MyBook:K that usually comes up. So I did some googling and went into disk management. The drive showed up on there, but when I tried to change the drive letter it said that it wasn't there and to refresh. I went to refresh, but with the drive plugged in, it took forever so I finally unplugged it and BAM refreshed (this goes for everything I try, if it is taking a long time and I unplug the drive it instantly comes up before closing). I also tried out my 500GB drive and that works just fine. So can anyone help me here? The drive was fine before I fixed the keyboard, but now it seems to be degenerating or something.

It seems like your drive has a lot of read errors, therefore have to find exact problem in order to fix it.
Most likely you will have to recover data, replace your drive and move on.
