If you open the Disk Management Console in Windows (Start >> Run... >> diskmgmt.msc) is the drive there? If the drive is listed there, or in the Device Manager (Start >> Run... >> devmgmt.msc) then this is most likely a soft or logical failure rather than a physical failure of the drive.

Problems that I have seen that do this:
-Damaged or lost MFT (sometimes fixable)
-Damaged or lost partition table (sometimes fixable)
-Physically damaged disk areas (recovery possible, but difficult; replacement needed)
-Full on mechanical failure of the drive (logic circuits work, causing the system to 'see' the drive at boot, but leaving it inaccessible; replacement needed).

In cases of hard or physical failure, if you absolutely need whatever was on the disk your best bet is a data recovery lab. The downside is that most will charge you a $100 diagnostic fee, and recovery fees somewhere north of $1,000.

all of the above are accurate.. would like to add one more I have seen fairly often.

if you have Goback installed, then have a problem with it, and try to remove it, it can leave the drive in a 'unreadable' state, due to not setting the partition type properly. In these cases, drive is seen in BIOS, seen in computer management (drive is there, size is know, but no drive letter assigned). the solution is to get the partition type reset properly, and we wont go into that unless needed.

You can try a usb HD enclosure (set the jumpers to master) and see if you can recover your data that way. I've seen stranger things than a failing HD sometimes work in different enviroments
