Answer 2

If you would liek to repair bad sectors, do not reformat. The following instructions are based on Windows XP Professional. All you have to do is close out all your currently rinning programs, go to My Computer. Right Click Your Local Hard Drive Which should be C:. NExt, you should get a popup window that has multiple tabs. On the tab that says tools, click that and move your mouse over to Error-Checking. Select Check Now And check both boxes, scan and fix bad sectors, and fix file system errors. That should take about 5-10 minutes if your computer is not lagging or does not have adware or spyware.

Answer 3

In certain limited cases, yes. The vast majority of the time, however, bad sectors are detected during the formatting process and marked by the drive/OS as unusable. Since they're permanently kept out of data storage pool from then on, they're "repaired" in that they're just never used. A small number of bad sectors is common, but a large or increasing number indicates impending drive failure.

...and run it. If it indicates that your drive is about to fail (which definitely seems to be the case) then your next step is to back up your data. Depending on how much you have to back up you can either burn it to CD/DVD or copy it to another internal or external hard drive. Whichever you choose, act quickly.

Answer 4

No, but during the formatting process, known bad sectors are put in a table so they won't get used.

Answer 5

try a system utilities program, at time they put in a folder; if the hard drive is getting real loud and scratch noise time to save (back disc import data). new hard drive.
