Computers by Disk Usage report issue

I've noticed an issue with the Disk Space Report.

It appears to round up all disks space in to the report to a single entry. Now although this data is correct it's kind of potless.

Here is a device

Computer Name - Total Capacity (GB) - Free Space (GB) - Free Space (%)
servername - 537 - 92 - 17

When investigating this device I've found that one disk has no space at all.

C:	Local Disk	NTFS	D8BB3980	60 GB	26 GB	56.70%
D:	Local Disk	NTFS	BA2AE36F	429493579776 GB	0 GB	%
L:	Local Disk	NTFS	C65E407D	77 GB	53 GB	31.20%
A:	Removable Disk	--	--	0 GB	0 GB	%

How do I run a report that shows any indervidual disks that have less than say 5GB.

Also can the pie chart on the inventory screen be changed to show the servers disk space breakdown that you see within Hardware \ Hard Disk.
