NASLite Network Attached Storage

I just installed a brand new 500GB hard drive, but when I completed formatting it, it is listed as only 458.6 GB. Also once the drive gets mounted, how can I dismount it ?

The 460G is formatted capacity and sounds right. You can dismount using the admin interface.

Wow. Am I gonna lose almost 10% of the drive capacity when formatted, thats almost 8 DVD's I could have stored

I can confirm this. My 500GB Seagate lists as 458.4GB Total in NL with currently 358.5GB used. Using Windows explorer it tells me that usage is "358 GB (384,461,218,816 bytes)". So you could claim that 384GB are in use, not 358GB (!) (Western Digital actually lost a class action law suit on this. Most of it has to do with what a KB is (1,024 or 1,000) and what a GB is (1,000,000,000 or 1,073,741,824). In other words, you could claim to be losing 73MB for each GB ... multiply that by 500 ! )

Ah, the old "when is a gigabyte not a gigabyte" problem.....

Basically, hard drives are sold in GB, i.e. 1000^3 bytes per GB, i.e. 1,000,000,000 bytes;

Not to be confused with GiB, i.e. 1024^3, i.e. 1,073,741,824 bytes.

So, if you divide your quoted size of hard drive in GB by 1.07374 you will get the size in GiB.

Yes it's annoying, no you won't persuade the hard drive manufacturers to change their advertising.

Simply put, k,M and G are base 10 prefixes meaning 1,000; 1,000,000 and 1,000,000,000.

ki, Mi and Gi are related to base 2 and mean 2^10, 2^20 and 2^30 respectively.
