It’s recommended that partitions are configured to begin on sector boundaries that are divisible by 64K. This will improve overall performance especially in random I/O workloads.
The following steps will assist in creating boot media that can then be used to align the system volume before an OS is loaded.
Step 1 – Creating BartPE boot media with DiskPart plugin
1) Download the latest version of BartPE (v3.1.10a used for this example)
2) Create an inf file as described on http://www.msfn.org/board/topic/27788-diskpart-ris-bartpe/ and copy the file to C:pebuilder3110apluginDiskpartition named diskpart.inf (or any name will do)
3) Enter location of the Windows media source
4) Open BartPE and click plugins – make sure both ‘Diskpart’ & ‘RpcSS needs to launch DComLaunch Service first – SP2 only’ are enabled (as below)
5) Select either create ISO image or burn to CD
Step 2 – Creating an aligned partition
1) Boot from the media just created
2) If required press F6 to install the 32-bit RAID drivers
3) Open a command prompt and enter the following commands:
- list disk
- select disk (enter number)
- create partition primary align=1024 (1024 is now the recommended alignment by Microsoft, more details available at http://support.microsoft.com/kb/929491/en-us)
