Diskpart.exe and Exchange 2003

[rws70]

I use the Dell server install disk to load Windows 2003 and create an OS partition. Unfortunately that does not result in an "aligned" disk.

See this URL for background on what "aligned" means:

Most of the articles on diskpart don't talk about creating new aligned partitions on disks with existing non-aligned partitions.

However I was able to create a new aligned subsequent partition using diskpart as follows below. (in this case I was creating a fourth partion of 68gigs and then labeling it F)

*******************************************

DISKPART> select disk 0

Disk 0 is now the selected disk.

DISKPART> create partition primary align=32 size=68000

DiskPart succeeded in creating the specified partition.

DISKPART> exit

(now I use dispar to check partition 4 stats ... note the offset 73270820864 is divisiable evenly by 4096 ... 73270820864/4096 = 17888384)

C:\Documents and Settings\Administrator>diskpar -i 0

---- Drive 0 Geometry Infomation ----
Cylinders = 17834
TracksPerCylinder = 255
SectorsPerTrack = 63
BytesPerSector = 512
DiskSize = 146689643520 (Bytes) = 139894 (MB)

---- Drive Partition 0 Infomation ----

---- Drive Partition 3 Infomation ----
StatringOffset = 73270820864
PartitionLength = 71304925696
HiddenSectors = 143107072
PartitionNumber = 4
PartitionType = 6

End of partition information. Total existing partitions: 4

C:\Documents and Settings\Administrator>diskpart

DISKPART> select disk 0

Disk 0 is now the selected disk.

DISKPART> select partition 4

Partition 4 is now the selected partition.

DISKPART> assign letter=f

DiskPart successfully assigned the drive letter or mount point.

Plan for performance, and capacity takes care of itself. Plan for capacity, and suffer poor performance.
