    • RE: SSD Alignment

      Hello Sebastian,

      this is my original d1.minimum.partitions file:

      label: dos
      label-id: 0x4ff028f0
      device: /dev/sda
      unit: sectors
      sector-size: 512
      
      /dev/sda1 : start=        2048, size=     2196723, type=7, bootable
      /dev/sda2 : start=     2198771, size=    75451766, type=7
      

      this is my original d1.partitions file:

      label: dos
      label-id: 0x4ff028f0
      device: /dev/sda
      unit: sectors
      sector-size: 512
      
      /dev/sda1 : start=        2048, size=     2196723, type=7, bootable
      /dev/sda2 : start=     2198771, size=   264139264, type=7
      

      What i did is to change the size of sda2 (my windows partition).
      The original start was 2198771 sectors x 512 Bytes = 1125770752 Bytes div 4096 equals = 274846,375 - not good !
      To align the partition correctly i used 2199552 sectors =
      1126170624 Bytes / 4096 = 274944 - that’s good !

      You just need to choose a sector start that is divisible by 4096.
      I took my size from a aligned partition where AS SSD showed me that
      1099776K would be ok. 1099776 x 1024 Bytes = 2199552 x 512 Bytes

      Easy maths - but it is annoying , here 512Bytes shown here, 1024 Bytes shown in AS SSD and 4K Bytes needed to calculate the correct sector size.
