Hello! And apologies in advance for not being able to keep this story shorter.
After different problems today, I've realized my main problem is the HDD. Here's the story; I started having issues with my wireless connection today, and as I usually would, I tried to restart my computer (it's the only thing that ever worked in these cases). It failed to start again though, told me it was was unable to due to some sort of "corrupt registry" and suggesting me to use the Vista repair. Ok, so I tried the Vista repair from the DVD and that failed too. So after a few more tries, I figured I should format the disk and reinstall Vista (this might have been bit impulsive and dumb). That failed too. I managed to format the C partition the first time, continued the install, but it stopped at 9% stating an error during the "expanding files" phase.
When I tried for the third time to install Vista, it just died after the black screen saying "Windows loading files". It obviously loads the installation files, I get the little green bar moving, then I get the Vista themed blue screen and an arrow, no installation pop up windows, no nothing. It just stands there with the arrow and I can't hear the DVD drive "working". Ok, so fresh install isn't going to work either. I figured the DVD is scratched or something.
Sooo I decided to atleast try and save my files on the other partition of that disk by connecting it to the same laptop (I put another disk with Vista installed inside my laptop - Toshiba Satellite L300, if this helps in any way), through the USB case thing. I've used it before and it worked fine with any disk, even a damaged one. But not this time!
When I connect the HDD through USB, the laptop does recognize it. BUT the only way I can access it is to safely remove it though. There is the icon offering to safely remove "driveS F: and G:". I can't access it through My Computer, Windows Explorer freezes when I try to even access My Computer. Disk management keeps saying "connecting to the virtual disk service". At one point I managed to open My Computer and it only showed one instead of two partitions of the HDD. When I clicked the one, it said I need to format the drive before using it. I tried to format (NTFS) the F partition and I was greeted with another bad news window saying Windows could not complete the format. EASEUS Partition Master recognized the HDD as only ONE 500GB partition at the same time.
I don't really know what to do with it now. I can't backup my files on the second partition because I can't open it, according to "safely remove hardware" there are TWO drives (please tell me he's the one that's right and the second partition isn't dead too) and Partition Master said there was only the one. I don't what I can do anymore, can't format, can't access it, nothing. I have tried connecting an external usb HDD I have, and that one worked fine. If that information is of any relevance.
The HDD is practically new, it's a 500GB WD, if that helps in any way. I'd like to atleast backup my files from the disk if possible, but I don't even know how to check if they are there anymore.
