I have a 500 GB Western Digital Passport, when I right click on the entire drive and check it's properties, it comes out to about 202 GB used, yet when I check the properties on all the folders from the root directory it is about 199 GB (and 201 GB on disk). Just curious where that extra bit of space goes, or if perhaps the calculation may be different?

Did you check for hidden files/folders?

Yup, I have all hidden files/folders set to show. Any other ideas?

The space unaccounted for may be used by the recycle bin to hold files that you "deleted." Windows also reserves something like 10% of the drive for the master file table which may account for the discrepancy.

What??

No no no no. If you don't know how something works, then don't try to explain.

There is a difference between how windows and the disc manufacturers define a GB. for Manufacturers 1GB= 1,000,000,000 bytes; For windows 1 GB = 1073741824 bytes.

That makes a 1 TB drive come up as only 931 GB in windows.

Are you telling me that NTFS partitions don't have an MFT now? I know about the difference in how hard drive manufacturers present the drive capacity and how it is measured by Windows. That's not what I'm talking about at all. I'm talking about the MFT. Perhaps you should take your own advice and not try to explain something when you don't know how it works.

They do, but not 10% of the drive. But given TC is only seeing a small discrepancy its probably the file system data structure using the space.

Fatali your response has no relevance here at all, read the OP.

Read through this, it explains everything:

In summary:
*1KB = 1024 bytes, not 1000 bytes.
*Memory manufactures sneakily advertise on the box by 1000 bytes.
*Cluster size matters. A file must take up a full cluster.
