Getting low-level disk info

How to get low-level disk info using WMIC.

The Windows Server 2000 Resource Kit included a command-line tool named diskpar.exe that could be used to display low-level disk info, but this tool is not included with Windows Server 2003 or later. How can you display this info if you don't have this tool?

Try the Windows Management Instrumentation Command-line (WMIC). Open a command prompt and type wmic diskdrive list and you get info like the following:

BytesPerSector 512
InterfaceType IDE
Partitions 3
Size 79999073280
TotalCylinders 9726
TotalHeads 255
TotalSectors 156248190
TotalTracks 2480130
TracksPerCylinder 255

and so on.
