sfc scannow vs HD check for errors

typo

Banned
What's the difference in terms of what they are and what they are used for? Without much understanding about their differences, I usually run both. And I really don't know what I accomplish by doing so. Is either enough? Or each one does things the other does not?

BTW...both scans give reports that I really do not understand. Can I safely delete SFC logs (CBS)?

SFC checks for corruption of the Operating System (Vista) and may be able to fix the problem.
Chckdsk, looks for errors on the hard drive.
Chkdsk, should be part of your regualr maintenance. SFC, is used primarily to find the source of a problem and correct it.
Quote from one of our tutorials on chkdsk

This will show you how to use and run Check Disk or chkdsk at startup from within Vista, the command prompt, and the registry to check for corruption and possibly repair errors and bad sectors on the hard drive.

10 Tips on How to Properly Maintain Your Computer

Steps that I did not notice on the guide include:

Running a scan disc before doing a defrag

Using Microsoft Security Essentials and Malwarebytes.

Making System Restore points, at least once a week

Makaing a system Image once a month (varies by user)

Not relying on your A/V common sense, should prevail. You know of many sites can cause a problem.

Do not use any reg cleaning or optimizing software.

Download and use Ccleaner about once every two months. Untick any registry entries.

If you follow these instructions, you will be trouble free for a long time to come.

Be sure to back up your hard drive about once a month (varies by user) and to keeep system restore points up to date.
