I have heard of a similar hack for DOS hard drives. It was described in the documentation for a hard drive utility called Spinrite. Basically, you create a DOS partition using, say, 10 cylindrers, which covers the boot tracks, then create another partition using some or all of the rest of the disk, this time a partition of reasonable size, and set this up as the bootable partition. They don't guarantee the process, and I haven't had to try it, but perhaps something similar could be done with a SCSI drive, maybe with Silverlining or some similar package. Anyone out there with a bad hard drive who feels like experimenting and would like to let us know what happened? This might be one of those undocumented features that will only work with certain hard drives.
