Crap lol, I got 2 drives.... one with Server 08 and the other with Vista Ultimate.
Yesterday I decided to do some disk cleanup on the Vista disk (while booted on the Vista partition), I did this after repairing my registry with Reg. Mechanic. When I saw how much was gonna be cleaned/deleted from my disk, I saw a whopping 109GB! o_O lol but I knew that Windows sometimes make errors in reporting memory info, so I went with the cleanup....
After like 15 minutes to the clean up, I noticed my desktop icons disappeared. But I assumed that it was my display doing a long refresh.
After the clean up, I then realized that 3/4 of my files have been deleted! WTF?! O_O It included ALL my music, videos, pictures; some program files; and most importantly.... a big chunk of my system files went missing O_O
Panicked, I rebooted my computer, hoping to wake up from this nightmare.... but because of missing system files, Windows was not able to boot up :'(
So I did what every man would do.... reformat
After installing Windows, I googled my problem and found out the cause of my problem.... registry cleaners
It said in a few articles and board discussions that a lot of people had experienced this problem already, and the cause was the registry cleaner deleting 2 keys in the registry that contained the cache info of the disk.... with this deleted, the disk cleanup utility gets confused and eats itself instead
So for guys who use Vista, have registry cleaners or/and are planning to install one soon (especially those who cleans up his drive regularly), UNINSTALL/DON'T EVEN THINK ABOUT IT! I know that Microsoft has a big problem in it's hands as this problem is now being experienced by a lot of people who use different kinds of registry cleaners (imagine the amount of data lost o.o), but before Microsoft does something.... us Vista users must 1st take necessary precautions while waiting for an update, I will keep you guys posted
PS: Good news though.... ALL my files are backed up weekly in a rewritable double layer DVD I own
btw, if any of you guys have (already) experienced this problem, take the time to share
