Re: Bad Sectors on a Formated Laptop Hard Drive
The format C: command you did won't do a thing - A)you can't run a checkdisk on the drive that the OS is loaded on B)without a switch (indicated with a /) the chkdsk will only do what is called a read only checkdisk on your PC - meaning it will just tell you if there are bad sectors but won't fix them.
As for formatting the entire drive, you will always have that extra 8kb or whatever space when formatting with a windows utility. I don't know the exact reason but there is on (i'm sure mak could fill you in).
As for fixing bad sectors - that is impossible. Bad sectors are parts of the hard drive that are physically bad, meaning they've lost their charge or just can't be read anymore. There is nothing that can fix this. The only 'work around' is to actually run a chkdsk on the drive, what that does is allow the OS to indicate which sectors are bad on the drive, then the OS will move what files are on that sector (if possible) and move them to a good sector. Then it will mark that sector as bad and won't use it. The issue with this is when you format a drive the OS looks at the drive as new, so it isn't going to know not to use a certain sector. So when completely formatting the hard drive then reinstalling the OS, the OS may install crucial components on bad sectors - causing the installation to fail.
All of this is assuming that the chkdsk you ran on C did find bad sectors. If that is the case it could very well be that the installation won't complete on that drive. To ensure that the hard drive is not the issue ensure you are using good ram (run memtest) and a good installation disk (try another computer).
Finally it has been my experience that once a hard drive starts failing, it fails at a catastrophic speed.
