I have two identical 1TB hard drives.  One drive's data has been repaired after some corruption.  The other is still in need of repair.  Particularly, the boot sector was corrupted and the backup boot sector corrupted and the partition doesn't list a filesystem type.  I am currently attempting to follow this article to fix the drive:  http://www.cgsecurity.org/wiki/Data_Recovery_Examples


Anyway, I'm using TestDisk, I can see the files/folders on the corrupted disk.  Even though the drives are identical, I noticed the number of sectors do not match.  Currently one drive is showing about 200MB more in the partition size than the other drive.




sectors for "Good" drive = 1953118377

sectors for "BAD" drive  = 1953525168



I don't understand why there is a mismatch in the number of sectors or how this will affect bringing back my RAID to life?  I also have no idea if there is actually any data in those extra sectors.
