Sedit (pronounced "S Edit") is a raw disk hex editor for SCSI and ATA
disks, similar to Norton Disk Edit, except it actually lets you make
changes!
From the doc:
> Sedit is a SCSI device editor and general purpose SCSI utility. It
> talks to any device on the SCSI bus. It can function as a block
> editor, much like [Fedit][1]. It also allows you to send SCSI
> commands directly out to any SCSI device.
>
> Warning!
>
> Sedit is a dangerous program. It will let you trash your disk, even
> the one you booted from. If the idea of staring at the raw contents
> of your hard disk in hex makes you uncomfortable, don't use Sedit.
>
> If you plan to use Sedit, remember that merely changing the
> information in the disk window doesn't change it on the disk, you
> have to select the Write menu. Once you have written to a disk,
> there is no undo command.
>
> The only commands that can change data on a disk are Write, Write to
> Block Number, Copy, and the custom SCSI commands.
