Windows 7: Windows 7 won't start, Caused by a forced shutdown during an I/O error

Windows 7 won't start, Caused by a forced shutdown during an I/O error

I was transferring about 150gb of files into my external hard drive, and left it alone as I went on with my day. I came home to an error, I should've paid more attention but it said something about an I/O error, and the files stopped transferring (or seemed to have stopped) Everything was really slow, I couldn't even open task manager (It actually opened up a long while after I hit ctrl+shift+esc) I couldn't close any of my programs (I have visual paradigm, which took about 400k of memory, skype [70k], chrome [200k], and some other stuff. I noticed svchost was 150k, but i don't know what that means. I finally closed all processes except for the file transfer screen, which said it was transferring but no numbers were changing. I hit cancel, waited. Could not safely remove hardware, it would not load the options. After about a half hour I gave up and force shut down my computer by holding the power button. I tried turning it back on immediately, with the external harddrive still attached. It froze at the windows start up screen, where it said Windows is Starting... But there was no swirly balls moving around if you know what I mean, it just had the text. Tried restarting again, same thing. Tried restarting and opening ubuntu, and it froze at the purple screen. Tried restarting again with the harddrive recovery, and it froze at a black screen, but I could still see my mouse and move it around. Restarted it again and now it brings up some text with PXE, media not plugged in insert a device and hit a key, something like that. I'm afraid of turning it on again, so I'm leaving it off for a while.

In retrospect, I made a lot of bad decisions that probably made the situation worse. For future reference, what should I have done in that situation when I first noticed the dramatic slow down?

Anyways, can anybody help me diagnose/solve this problem? I would greatly appreciate it as I'm pretty sad about this whole ordeal. I can provide any more information as necessary, I will be actively watching this thread

Many thanks in advance :)

Sounds like a failed HD, but make sure your external is unplugged when restarting to be sure.

Then enter BIOS setup to see if HDD is detected. If not replace cables to see if they're faulty. If not replace HD.

If detected run maker's HD Diagnostic extended CD scan.
