Why has XP reduced total capacity of my HDDs

December 5, 2010 at 04:47:15
Specs: Windows XP SP3, 1.5Mhz
I have 2 hard drives, my main C, was 80GB and now it has randomly gone to 32.49GB, but that is it's total capacity that has been reduced, not the free space, my second drive D, was 80GB and is 74.53GB now.

Why has my computer reduced the total capacity of my hard drives?

The 80G D drive will always show as about 74G in Windows. That is because drive makers advertise drive capacity in decimal measurement (1000 mb per gb) whereas Windows uses binary measurement (1024mb per Gb)
This difference has been asked about and explained countless times.
As for your C drive that's a different matter. Go into Control Panel > Admin Tools > Computer Management and select Disk Management from the menu in the left panel.
Now look at the lower section of the right panel. Your two physical disks should be identified there together with whatever partitions are present. I suspect you will find an 80GB Disk 0 with a 32Gb C partition and remaining space shown as Raw. Suspect it will be a FAT32 partition and this happened when XP was first installed.
XP's setup has a 32Gb size limit if you use it to partition & format a drive as FAT32

My C Drive used to be 80GB (Well 74.53GB) but a few months ago it changed from that to the 32.49GB, but I don't understand why it has changed because I've had and used the computer for about 4 years now, the only thing that's changed in the last year is that I've got the Internet, Anti-Virus Software (Avast), but I've had to re-install XP a few times because it got messed up (missing software, slow, freezing/resetting etc.).

"but I've had to re-install XP a few times because it got messed up"

During one of those re-installs you must have deleted the original partition of 80g on the primary drive and created a new smaller partition. Did you go into Disk Management and check the physical attributes of the Disk 0 ? Does it show any unallocated space?

My friend said that Formatting the C Drive will get it back to the 80GB, will it?

In Disk Manager this is what came:

Disk 0 is the D Drive (74.53 GB)
and Disk 1 is C Drive (main, 31.49GB)
In the Disk 1/C Drive Properties is shows 32248 MB Capacity and 0MB Unallocated Space and 0MB Reserved Space, it also says that the Partition Style is Master Boot Record (MBR)

I may have overlooked the part when you said you had XP messing up. Missing files, going slow. locking up.

The drive in question may indeed have a problem and the only way to know for sure would be to download a drive diagnostic tool from the company that made the drive. These tools are run from either a bootable floppy or CD. If your system has a floppy drive that works then download the floppy version of the tool. Put a blank floppy in the drive and run the downloaded file. It creates the bootdisk and writes the tool onto the floppy. You then make sure Floppy is set as first boot device in bios and boot up the floppy diagnostic. Carefully look at the testing options as some of them will wipe the hard drive. While you are in BIOS look at the drive properties and see if that drive is detected as 32 or 80gb

There is no Floppy Disk Drive in the Computer
