I'm trying to understand what an MBR is. I know it is used to boot the device, like a compact flash card.
If you had five 1GB CF card from SanDisk for a camera, would there be any reason for the manufacturer to have different MBRs? It seems like to me, if for some reason one CF card wouldn't boot, you could copy the MBR from a working CF card and write it to the non-working CF card.
Would this MBR for a SanDisk card work on the same size Western Digital card for the same use?
