Bad Sectors - Windows Server 2003

January 5, 2011 at 09:40:18
Specs: Windows Server 2003
Server shut down the other night due to bad sectors found on the HD. Boot ups since have indicuated no DHCP exists. Any utils available to recover these bad sectors? Regular Chkdsk function doesn't work - windows cancels it right after starting it (during subsequent boot)

bad sectors are failed media. There is no repair for that. Only thing you can do is run a utility like chkdsk to mark them as unusable.

How many bad sectors are we talking here?

Thanks for your reply. I've had tried the chkdsk utility at boot-up and the screen display shows that right after it starts running, it's cancelled.
I'm wondering if there's any other utility that does the same thing, but works better in the Windows Server 2003 environment? I need to move what's in the bad sector to a good sector and chkdsk is the only thing I know of. It's not a big sector, but it must contain boot-up info, as my DHCP is now not running. Any thoughts? Otherwise it's on to a data recovery service, I suppose.

You should go into recovery console and run chkdsk /p

The file system only addresses clusters of which is a collection of sectors. A single sector bad means the cluster isn't usable. Standard cluster size is 4K

I would suspect a bad cluster is not the reason your dhcp server is down. First stop is review the event viewer logs. Try to manually start the service and if it doesn't start post the event viewer error.
