HI All,
any idea on how to get the size of the harddisk? not only the system drive but the actual size of the harddisk installed with or without partions.
Thanks,
Braian

I recently figured out how to do this using WMI
See the “
Raw Size of SystemDrive
” property of the “
Hard Drive Audit - Windows
” analysis here:
http://bigfix.me/analysis/details/2994701
Also see the related and supplementary “
Hard Drive Audit - Universal
” analysis here:

Hi jgstew,
Thanks for the link, this work for most of our workstation but some reported as “Singular expression refers to nonexistent object.” i have notice that there are two property “size” w/ value and the other is without value. how can i edit the analysis to eliminate the error “Singular expression refers to nonexistent object.” and get the value of the size property. I’m not sure if there is USB connected.
here is the properties of win32_drive from a workstation with error:

The property should not result in an error as written based upon the result you listed.
The machine you are saying gives an error has 2 dives in it, the system drive and a USB drive. The USB drive does not report a size, but it looks like the system drive does. The property only tries to get the size of the disk at index 0, which does appear to have a proper size, so I’m not sure why there is an error in this case.
It might be possible to do something to the WMI query. Try this:
((it as integer) of string values of selects "Size from Win32_DiskDrive WHERE Index=0 AND size!=’’ " of wmi)

Actually, it might be the case that “Index=0” does not always indicate the system drive. I see 1 system in our environment that has a ZIP drive that appears to be reporting as Index=0

hi jgstew,
thanks again for the help, as i have notice the error is gone but the workstation with 2 physical hdd will only report 1 value instead of multiple result.thanks

If you wanted to get all sizes of all drives with sizes instead of just the size of the drive at index=0, then try this:
((it as integer) of string values of selects "Size from Win32_DiskDrive WHERE size!=’’ " of wmi)
I have updated the analysis I referenced above to include the check for size!=’’ (

thanks jgstew, ihave tried this analysis and have an error, i am also trying to edit the analysis. please post for any suggestion.
if (exists wmi) then ((string value of property “size” of it as integer / 1024/1024/1024) as string & " GB") of (select objects "Size from Win32_DiskDrive WHERE size!=’’ " of wmi) else nothings
result is:
465 GB
singular expression refers to nonexistent object.
