traces of bad block/sector

by yongtw123 / February 7, 2008 1:24 AM PST

One of my hard drives are not in very good condition; it has some bad blocks and sectors. I used ChkDsk many times and repaired whenever it could. Weeks ago I reformatted that drive and created a whole new partition. Now at least the "bad block" or "bad sector" errors won't pop up every minute.

I just want to ask, when I am using my hard drive, and data just happens to be written near the "marked/fixed" bad sectors/blocks, should Event Viewer be alerting me of these bad sectors/blocks? Aren't these inconsistencies marked by the drive and never used again? In other words, maybe Event Viewer is just reminding me that on the disk surface the problems still exist physically? Maybe I shouldn't be too worried? Maybe the data won't be corrupted unless Windows tell me so?

I clone the drive to a new one and send the old bad one to silicon heaven.

Does the poster know how to do this?

dd isn't a command line for the average user, much less a person that only uses a windows nt release. The poster may need someone to help.

In order to use G4U for cloning

The person will either have to set up an ftp account with a large bandwidth and space
make a server with a linux distro, fedora being the easiest to use in this case.
personally, it looks like dd with a few extra command lines.

I used it last week for a disk to disk copy.

In reply to: Bah!

But we are talking of someone who needs a basic tutorial on using a copy command. The tutorial given is easy for people used to a *nix system but
it is difficult and confusing to the average user.
the only other solution I can think of is to have someone make a modified net install debian disk with ntfs added to the partitioner or a command line only with the ntfs partition option available and use that to copy from disk to disk.

Bad disk sector solution
by welrdelr / February 8, 2008 9:14 AM PST

You will need another hard drive of the exact same size.
Attach it to the cable.
Burn a knoppix disk and boot up according to a tutorial I have posted- see earlier posts.
Mount both disks and click open.
the one with folders and files will be the one you want to copy
mark the new disk as writable.
open the terminal on the bottom- looks like a monitor.
type "sudo su" and hit enter
type "dd if=/dev/hd? of=/dev/hd?" where the question mark is the disk name for the first.
If sd is used then it will be "dd if=/dev/sd? of=/dev/sd?" with the same rules applying.

For the next choice you will instead type "qtparted" where the dd command was and mount the disk that is new. choose format as in the right click menu and choose ntfs. choose commit in the drop down menu.
choose quit and return to the terminal
type "exit" and continue with the next part of the tutorial.

If you are willing, you could try the cp command such type "cp /dev/hd or sd?/location/of/folder /dev/name/of/new/disk"

G4U copy is "one line"

Please read Porch a Geese other posts and sadly I think we may have to share the answers rather than dive into the empty deep end of the pool. That can hurt.
