LS-X3.0TL Capacity?

[mark100]

I have the LS-X3.0TL model with 3 TB supposed capacity.  I know the firmware is supposed to take some space but 3 TB should be 3072 gigabytes.  In the NASNavigator software I am seeing this:

 

Internal HDD 282.7GB / 2779.7GB (10.2%)

 

Firmware: 1.62

 

(The 2779.7 number is supposed to be the total, not the remaining)

 

Is this the right capacity?  It looks to me like ~300GB went somewhere.

Manufacturers count what constitutes a TB in a different way than Windows does, using a factor of 1000 instead of 1024.
1,000,000,000,000 bytes
/ 1024 = 976,562,500 kB
/ 1024 = 953,674 MB
/ 1024 = 931 GB x 3 =2793GB - some more space or firmware, boot images etc

A "proper" TB = 1000 GB would be 1,099,511,627,776 bytes.

This is standard practice for storage manufacturers.

Windows?

 

I don't follow your math.  How is it that you can use 1000 for the numerator and still use 1024 for the denominator?  Seems inconsistent to me. 

 

And if this is "standard practice" how is it that OSX, for example, is reporting the capacity of my 1 TB internal drive as 999.86 GB and 1 TB for my 1 TB external drive (961.2 GB used, 38.87 GB available)?
