Title: 2tb Upgrade Partition Size Xbpartitioner
Post by: Bomb Bloke on April 05, 2010, 06:05:00 PM
Two "manufacturer's" terabytes = 2,000,000,000,000 bytes.

This equals about 1862 "real" gigabytes.

948,965 megabytes = about 925 gigabytes, meaning that your F+G partitions total around 1851gb. Note that you also have three cache partitions (X, Y and Z), which account for 750mb each. So all the math about checks out.

This difference between what driver maker's advertise and what the OS sees will only get more and more pronounced as drive sizes increase.

I recommend you double check that the right cluster size got used on your F/G partitions. Using the EvoX dash, note the free space on them, then copy a single file over to each (10kb or less). The difference in free space, divided by 1024, is the cluster size.

yea id say 100 gig lost is about right with that size hdd. with cluster sizes so large and how BB explained actual size compared to manufactures size statements.

The 100G isn't lost (it isn't there in the first place), and it has nothing to do with cluster sizes..... smile.gif

well its lost in terms of what he thought he was getting and what he got.

and with larger clusters there will be more unused or un-utilized space (especially with many small files like in games and such). it wont add to how large or small the partitions look. however allocating out a hard drive (or formatting rather) does decrease the "size" of the partitions. for instance i buy a 2 gig micro sd card, it reads 1.82 gigs, i format it for my phone and it only reads 1.78 (or whatever).

eh, its technically the computers that are wrong, "giga" does mean 1,000,000,000, lol

theres been some push to use a different prefix, "gibi" to mean 1,073,741,824 (1024*1024*1024) and the associated terms for thje other sizes are kibi, mebi, gibi and tebi



its a confusing system to the uninitiated to say the least

I would probably be more accepting towards the "let's use a different prefix" movement if they weren't pushing terms that make us sound like pre-schoolers. Seriously, try talking about gibibytes out loud and see how far you get.

I know SI might have logic on their side here, but you don't mess with tradition!!  tongue.gif
