Hello, I have a HP G60 418CA laptop. The laptop came with Vista Premium, but I upgraded it to Windows 7 professional. After I upgraded it, I noticed that every three four days, when starting the computer, it runs Disk Consistency Check. I am sure I didn't restart the computer improperly. And I also tried checking the disk manually, I checked both automatically fix file system errors and scan and attempt recovery of bad sectors, and it returned saying no errors found. So I am wondering why there is the frequent disk check. The drive is ST9320325AS ATA DEVICE.
