Have you ever noticed that a hard drive never shows the memory that it is rated with in 'Properties', after taking into account the memory used for the operating system and installed programs. What exactly has happened to this missing memory?
You mean storage space rather than memory, mcheathen?
It is taken up by hidden system files and folders and in the way that the size of the drive is measured. A manufacturer will state that a hard drive is, say, 100GB in size, using 1000MB to equal 1GB, while Windows will see it as less that 100GB because, actually, there are 1024MB in 1GB.
If Windows sess a GB as 1024 MB, then that would make more sense - thanks! So wiht my hard drive as 488 GB, there will be (according to iqs) 23GB used for the low level format,track,sectors and whatever the etc etc actually is. That still seems like quite a lot!
Drives are already "formatted (low-level)" when new. The amount lost by user partitioning/formatting is really tiny.
You can see that in the Drive Properties. Windows will show the capacity in actual Bytes (500,000,000,000 - or a few more in most cases) - as well as in GBytes calculated on the 1024=1KB method).
You really do get 500,000,000,000 bytes of storage - though the filing system uses a little in tables etc - and the OS quite a bit more. That's still your storage though - used to store the stuff of your system. Your system of course must store OS, programs and your data - it's all your stuff to store, whatever it's used for.
