Volume C: in this computer is a 30G. Windows reports it at around 18, and the BIOS reports is as 20020 MB. All of the Googling I've done is for
-Wrong size reported while installing hard drive
-Wrong partition size (which I read as applying to a partitioned drive)
-Wrong size shown only in Windows Explorer
None of these apply to me. There are no "extenuating circumstances" besides the possibly of a setting or registry key or something, and the wrong size applies all over. The paging file is about 2 gigs so that is probably why the BIO size differs from Windows' reported size.
With a 30G hard drive it is important to have the correct size reported. Can somebody help me? Thanks.
