I need to grab a copy of the MBR from my system and compare it after changes are made. I don't see a way to do it in TI, but I see DD has the option.... but unfortunately when I go to it, it's grayed out for all my partitions. What does that mean?

DD will only let you copy the MBR to another drive.

If you use the Disk Editor feature of DD you can save a file with the MBR sector. Just edit the disk, select sector 0, and save the sector to a file. You can then read that file into another sector to compare them or write another file with the modifed data and compare the files.

So when you say it copies to another drive, you mean it writes it as the MBR for that drive? Not that it copies it over as a file?

That's correct. If you want it in a file you would need to use the Disk Editor. Keep in mind that if you save the entire MBR sector (sector 0) that it also includes the partition table. If you then write this back to a drive the partition table will also be written. This will cause problems/corruption if the partitions on the drive are different from those saved in the MBR file. If you just want the "code" part of the MBR, you may want to just save that part.
