    Advanced format drive - replacing a failed RAID member

    I have an 8 disk array of Seagate 1.5TB 5900 "green" drives.
    I had one go bad and Seagate replaced it under warranty.

    The drive I got as a replacement was an "Advanced Format" drive.

    Code:
    Old drive: 
    Model Family:     Seagate Barracuda LP
    Serial Number:    9XW05B85
      5 Reallocated_Sector_Ct   0x0033   100   100   036    Pre-fail  Always       -       0
    197 Current_Pending_Sector  0x0012   100   100   000    Old_age   Always       -       0
     
    New drive:
    Model Family:     Seagate Barracuda Green (Adv. Format)
    Serial Number:    6YD05MN6
      5 Reallocated_Sector_Ct   0x0033   100   100   036    Pre-fail  Always       -       0
    197 Current_Pending_Sector  0x0012   100   100   000    Old_age   Always       -       0

    The block counts were slightly different on the drives - the new one was slightly larger.
    I used sfdisk to duplicate the partitons from another drive and added it to the array.
    It's just a few minutes away from rebuilding.

    How much if any problems will this different format drive cause me?

    Since you used sfdisk and copied the partition table over from the previous setup, this will work great This is exactly the reason I recommend to use partitions vs. the whole disk for mdadm (it's also nice to be able to properly align the partition).
