I have a hard disk that I scanned with TechTool and it reports one bad block. As far as I can tell, TechTool only scans and reports a failure. It doesn't fix anything.

Back in the day, Norton Disk Doctor did the job of scanning and flagging (remapping) bad blocks on the Mac. Today we have various tools for fixing up HFS+ directory errors (Disk Utility, fsck, DiskWarrior, TechTool), but I don't know of any tool that will do a surface scan and fix the bad blocks too.

What software is available for this?

If I know the address of the bad block, is there a low-level terminal utility for marking it?
