A really strange hard drive problem
Recently I bought a dell 1521 with 160 gig hard drive. 136 gigs have been allocated for the normal c drive, 10 for the backups drive, and the rest unnallocated. the problem is that the c drive says I am using up 31.5 gigs. However, even after making sure all hidden files are displayed, all of the files in the hard drive only make up 18.5 gigs (Including pagefile). that means there is over 10 gigs unnaccounted for. can anyone tell me whats going on here?
1000*1000 is how they do it, not 1024*1024.
To expound upon what Jyuu said:
Everyone notices, and is befuddled by this problem at some point. I remember calling (this was a few years back, say, 5)my HDD manufacturer and waiting on hold an hour before someone explained that to me on the phone like I was a moron. Count yourself blessed you didn't make an ass of yourself.

thanks to Silverwmoon!
I don't think that's the solution to his problem. He's not saying that the total size of the HDD differs from what was specified by the manufacturer, he's saying that Windows gives him different C drive usage statistics when he checks it by highlighting his drive in "My Computer", and when he selects all the files in C: and checks their properties. The difference in measurements isn't large enough to account for a difference of over 30%. Most likely it's a combination of the following:
- Windows is using the C drive to store the pagefile (virtual memory) and it isn't being displayed when you select all of the files. This usually takes from 2GB to 4GB of space.
- Cluster size, combined with the large amount of small files littering the C drive, is creating a lot of wasted space. Basically, there's a minimum size to the amount of space that can be allocated for a file (known as "cluster size", it's usually somewhere between 2KB and 4KB depending on partition size and the file system being used). Any file that is less than the cluster size still takes up the entire cluster. When you check a file's properties Windows usually tells you the exact size of the file, not the physical space used on the disk, but when you check your HDD usage in My Computer I'm pretty sure it tells you the physical HDD space usage instead.
- There's a property for files in Windows known as "super hidden". Even when you show hidden files, these "super hidden" files will still not show up. The only way to view them is by editing the registry. I believe that both Windows and Internet Explorer keep some temporary files in super hidden folders.

I remember Dell installing some other stuff on their laptops, some sort of partition that allows you to play CDs, DVDs without booting into Windows, but that should only take 1-2 GB.
If you're that worried about it, do a reformat, formatting every partition Dell puts on there, and see if you're still losing space.
IIRC, Dell puts a crapload of pre-loaded stuff on their comps, so a clean format is usually a good idea, be warned that you'll lose the backup partition (not a big deal if you have the install disks), and the media play stuff, you can still keep it, or install it yourself, but not without a reformat.
