it's a *bad* sector, so reading and recovering the data is a bitch...No, storing in Negative Disk, bad sector, stenography, slack space are all bad places to store data!
No, I meant it's usually not worth worrying that if the disk has done a hardware assignment of a replacement sector for a *real* live actual the-hardware-barfs-on-it bad sector, you can usually not worry about the contents of that bad sector, as the drive hardware won't let you access it directly anymore, redirecting you to the new replacement block. So basically, somebody needs to take the disk apart and start doing the clean-room data recovery routine off the disk, trying to read 512 bytes of data at a time off known-physically-bad areas of the disk. And if your threat model includes adversaries that will do that, then you *really* need to be using full-disk encryption and thermite in your counter-defenses. Oh, and a good countermeasure for rubber-hose crypto. ;)
