Determine the order of the physical disks in the array

The first disk can be identified by an MBR that contains an entry resembling the original extent of the logical RAID disk. For example, if two identically-sized disks were used, then the end-sector of the MBR entry would be approximately twice the number of total sectors on a single disk. The other disks would contain MBRs with odd entries and can be ignored. If it is unclear or all values are nonsensical, the next step will help.

Here is an example of the human-readable values in the MBR from the recovered RAID array:

This calculation doesn’t make sense to me: isn’t #Total = (#Last - #First + 1)? Therefore I assume it should be 976768003 total physical sectors. Regardless, one must use the numbers seen in the NTFS partition information sector described later.
