Why have I "lost" hd space

My second hdd is 60g and is unpartitioned. I know the actual available space is not 60g but 57.2g. When I check properties it shows 20.9g used & 36.3g free = 57.2g. However when I select all the folders on the drive and check properties it shows 15.8g used rather than 20.9g. The reserved space for the recycle bin is set at 1%, so is just over 0.5g.So where has the rest of the space gone? My os is W2000 sp4 with ntfs. Any help / advice / info appreciated

It all depends what you have loaded on the second hdd,the likes of avi and pictures take a lot of space.

is the 15.8 GB the "size" or "size on disk" ??

expertec - "size" & "size on disk" are both 15.8gb ;-) k.

you have any sort of system restore or "go back" software installed?

Have you had a CDR burn failure of late if so there may be a backup somewhere on your drives? Check the Root in each Drive for big files

Also when you say that you check folders did you include the Root File which include the very Big Swap file

"where has the rest of the space gone"

Hidden folders??

I have found that if you use the NTFS file system, there is a difference between file size and actual disk space taken up. For example I have a 23.0KB word document, but it actually occupies 24.0KB of disk space. With lots of files this actual disk space and file size will mount up.

You may have lots of 'Hidden' files counted in one display and not the other.

With all filing systems there is slack (lost) space.

Since space is allocated in multiples of fixed length clusters - on average there is half a cluster lost for every file.

For example, if you system has 16Kb clusters, the slack space will be approximately 8Kb times the number of files.

NTFS has less slack space usually that FAT32, as it's cluster sizes are normally smaller.
