I think the program "badblocks" will check a disk for bad blocks (by running read and *more dangerously* write tests). This program produces the list of bad blocks in a manner which can be used by file system tools to mark blocks as unusable.

If you are using the disk, then it is best to run this in read-only mode. For example, for an ext2/3 file system on /dev/sda5 you would use

 e2fsck -c /dev/sda5

This command will call "badblocks" in read-only mode to perform the disk scan. This operation can take a long time for large disks. Note that any file data that has already been written to these blocks before performing the check might not be recoverable.

If you are not using the disk and are planning to check for badblocks before using it then it is best to again use file system tools to check the bad blocks and create the file system in one command. For example, to create an ext2/3 file system on /dev/sda5 you would use mke2fs -c -c /dev/sda5 Specifying -c twice will make the badblocks program check for write access as well and this will be take twice the time of the read-only check (typically).

There is no way to "remove" bad sectors entirely --- one can only mark them as bad so that the operating system will ignore these sectors while using the disk.

How's this for easy:

STOP. SPAMMING. US.

Asking a question in a help forum is reasonable. Sending the same message again and again while ignoring the replies to your original question is damn rude.

Rashid, just as incentive: Ben's the nice guy. I'm the nasty mean sysadmin with the trigger finger on the system-wide conffiles who can and will terminate your ability to send any mail to _Linux Gazette's_ TAG mailing address permanently if you don't follow Ben's good advice immediately. So, you're going to want to do that.

(I've been away for two weeks, and so was unaware of your having abused the mailing list until now.)

Oops, this may have partly been my fault! My reply did not have a copy to querent.

Sending him a separate copy now with a request to reply to the list.
