Hi all, Is there a util in Linux that will perform a surface scan of a hard disk to locate bad sectors and mark them as unusable? Something similar to Windows Scandisk util. I recall during the Redhat installation routine there was a check box that I could select to perform a surface scan. What utility does this? I have a hard drive I'm trying to get data from but there are a few bad sectors and as a result I'm unable to pull an image of the drive. I would like to mark those sectors as bad, so I can then pull the image and get most of the data off the drive. I tried using fsck, but it only seems to check if the filesystem is contiguous. It says that the filesystem is clean. Any help would be appreciated. Peter
