Madhan/Mathan - This is definitely a sort of deja vu situation for me. I recently had a sort of similar experience. Though, my situation was a bit worse. I just got through installing Windows 7 on a 1 Terabyte Western Digital drive and after a reboot, it reported the hard drive had shrunk to 33 Megabytes. Needless to say, the drive was toast. Good thing it was still under warranty. Now then... The first thing I would do is boot the system and go into the system's BIOS. Take a look at the basic screen and check the hard drive. Is it reporting the correct size there? Secondly, most hardware vendors have a diagnostic utility for their drives that will run under Windows. Check to see what brand you've got and go to the manufacturer's site and grab their utility. Install and run it to see if it sees anything hinky with the drive. Third, you might want to check to see if it's still under warranty. If it is, you might want to contact the manufacturer for an RMA. If it isn't you're going to need to go out and buy a replacement drive. Either way - I would highly recommend moving your data off onto another drive or some other form of backup - complete with a verification ASAP. Depending on what the utility reports, you may want to consider doing a reinstallation of Windows 7 to avoid future problems from using a corrupted copy of Windows from the old drive.

How did you part the drive originally? If you part with any third party tools, there may be compatibility issues so the disk management tool cannot read the partition table. If it is the case you may need to reinstall Windows 7 and re-format during the installation.Arthur Xie - MSFT
