Re: Partition Alignment

Hi,

 

after investigating the output of fdisk or sfdisk I encountered an odd number of heads of the virtual disk:

 

Disk /dev/sda: 1305 cylinders, 255 heads, 63 sectors/track

 

255 heads is quite a lot I think. I also encountered an odd cylinder partitioning:

 

Device Boot Start     End   #cyls    #blocks   Id  System
/dev/sda1   *      0+     42-     43-    340992   83  Linux
/dev/sda2         42+   1305-   1263-  10141697    5  Extended
/dev/sda3          0       -       0          0    0  Empty
/dev/sda4          0       -       0          0    0  Empty
/dev/sda5         42+    499-    458-   3672064   83  Linux
/dev/sda6        499+    722-    223-   1783808   83  Linux
/dev/sda7        722+    795-     74-    589824   82  Linux swap / Solaris
/dev/sda8        795+    835-     40-    316416   83  Linux
/dev/sda9        835+   1305-    471-   3775488   83  Linux

 

The + or - character indicates that the number is rounded which can't be true on a physical disk because each partition seems to be placed not on a correct cylinder boundary. In Fusion I setup a virtual disk with a size of 5 GB, could that be the reason of that curios disk geometric?

 

Now I'm confused...

 

Thx & Bye Tom
