how to instruct ext3 to not use bad blocks ?

Maaz — Fri, 12 Sep 2008 04:44:48 GMT

I have a disk with some bad blocks. How can I instruct the ext3(at the time of formating) to mark those bad blocks and do not use the marked area(bad blocks), so that I can use the disk/media without any worry

Regards

-c Check the device for bad blocks before creating the file system. If this option is specified twice, then a slower, destructive, read-write test is used instead of a fast read-only test.

-c is the parameter for the mkfs.ext3 command.

Hi,
It will very good if you will replace this disk with new one.
It is observer that, these kind of BAD sector disks are making problem in future.
If your Application is Critical installed in that system, then you have to have replace with new one. If its not ypu can repaire with different tools available.
