External HDD "You must format this disk before you can use it"
Hello guys.

Yesterday I freshly-installed Windows 7 x64 on my computer. After having done the installation, I installed my anti-virus, firewall, etc. and also plugged in my Western Digital external HDD (where I backed up my files), and all was working fine and dandy.

I then left my computer running overnight so that it may install all the Windows Updates, and in the morning I check up on it and they're finished, so all that's left now is to restart the computer. I do so, but then when I go and check my external, I can't even open it. If I right-click it from Computer, Windows Explorer stops responding. Eventually it gave me a message that said something like "You must format this disk drive before you can use it. Format it now?".

I tried using chkdisk, but even when I type the drive letter (e:) it gives me a message in the cmd saying "Data error <cyclic redundancy check>". No idea what that means. I also tried plugging it in my laptop, but nothing happened. No response, no notification, no drive in Computer, nothing. Only the light on the drive turned on.

Does this mean my external is done for? Or was it due to the Windows Update? If so, can it be fixed?

Help would be greatly appreciated. Thank you.

(I enabled the Administrator account, and tried to access the external via Computer, but it gave me the same message as it did on the cmd, this time in the form of a window pop pup. Also, I'm trying to understand the CRC thing, but I still don't really know what that means.)
