My Windows 7 version of bitcoin-qt suddenly crashed while syncing with the error message "*** System error: Database Corrupted".  Now each time I try to open the program, I get the same error and it immediately closes.  Below is a dump from debug.log.  Does anyone know how I can fix this?  (Hopefully without doing a full reinstall and re-downloading the entire blockchain all over again.)

After unsuccessfully trying to get bitcoin-qt running again by deleting the most recent blockchain files, I simply uninstalled the whole program, restarted the computer, deleted everything in C:\Users\BZ\AppData\Roaming\Bitcoin, and reinstalled a fresh copy of 0.8.1.  The block chain sync had been running for several hours, and I had about 30,000 more blocks to go, when it crashed again in exactly the same way.

This seems like a pretty serious problem.  Are there any other reports of this or known solutions?

It is possible your hard drive is dieing. Undecided 
Maybe someone will come along with a more positive solution. Wink
