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.

Hi Sebastian,

when i don’t use the resizable image option i will not be able to install the image to smaller drives , right ?

I found a way to correct it.

I changed the starting sector in d1.minimum.partitions and d1.partitions file to a size which can be divided through 4096. Then i get a aligned layout.
Maybe you can change that in a future version as not only ssds need that , newer hdds also need 4k sector size.

thank you.

Hello from germany,

i use FOG to install images to different kind of notebooks.
Everything works fine. But the alignment of partitions is beeing corrupted when restoring images to SSDs.
Is there something i can do ?

I’m on Version 1.5.9-RC1
