The Great Capacity Swindle
« on: April 30, 2008, 11:30:56 PM »
I bought an external hard drive today, the internal 40Gb was simply too small for my music collection and everything else I was used to having on the Mac's 60Gb drive. I have kept the internal and got a cheap Western Digital Elements drive at 160Gb for £49, only it's er.... not 160Gb.

Unfortunately this is nothing new in the market, disk manufacturers have been rounding up capacities for many years.
Take the 1980s for example. The Double-Density floppy disk advertised having a whopping 720k storage at the time, but actually DOS systems could only access 713k of it. The Amiga was not whiter than white either, with its standard 880k disks only usually containing 837k of space.

The so-called 40Gb hard disk in my box is actually only 33, and today I discovered the 160Gb drive I just purchased is actually only 149Gb. This is ridiculous.

This isn't a few megabytes of difference, it is a whopping 11 gigabytes less than advertised. Enough for a fully configured OS install and a fat wad of applications and some MP3s thrown in. A lot of space.

Now if it was 159Gb then that would be understandable, marketing a "160Gb" drive makes more sense. It would also be understandable if they marketed my drive as having a "150Gb" capacity.

I think manufacturers need to be more honest and stop this before eventually we will be seeing 1Tb drives with only around 800Gb of actual storage space.

Being the modest honest guy I am, when people ask me the capacity of the drive, I will say 150Gb. It's a shame manufacturers can't apply the same honesty.

Well without altering the filesystem on my new one, it shows as 149Gb, it uses the somewhat appropriately named "vfat" filesystem  :lol:

Or else you should just realise how the manufactures calculate their GBs.

Manufaturer
160 GB = 160 x 1000 x 1000 x 1000

Computer system
(160 x 1000 x 1000 x 1000) / (1024 x 1024 x 1024) = 149 GB.

Now do the math, and you will know how much storage space you have from your future TB drive.


Nowhere near a full terrabyte.
I'm amazed no one has complained about this sort of thing in the past, on the lines of false-advertising or at least misleading the public into thinking they will have a full X amount of space when really they get significantly less.

Welcome to the early 1990s ?

Seriously man...it's common knowledge that the decimal powers of ten are in use since then for storage...and the rest goes to formatting.

Although you did actually get 720kB on a floppy back in the day...7 was used for formatting.


It is common knowledge, but why? It is wrong and misleading IMO. Not everyone is as knowledgeable about computers as the people who use this forum, and it might seem like a small petty issue to some but in my opinion if Joe Public buys a hard drive marketed at a certain capacity, then they should be able to access that capacity.

If a chunk of it is used for other data then take that extra off the marketed capacity.

Off topic issue but you were ripped off anyway...

I got a 320gb external IOMega drive for about £50 just after christmas...

But yeah, they allways do calculate the capacity wrongly, I thought it was common knowledge.

Only problem I have with the external HD is the speed, backing  up over USB2.0 isn't really realistic... and I haven't found anything nearly as good as Time Machine for XP/Vista.



I know, but it was bought on impulse and out of Maplin and Currys Digital (which are probably the same company anyway) the Currys Digital WD one was cheaper (Maplin wanted £80 for the same capacity but a DRM one)

Sooner or later though, they are going to have to change aren't they, because the gap is getting increasingly bigger everytime, when it goes into hundreds of gigabytes surely its time to change the way the capacity is marketed

The XBOX 360 drive is worse, they say 20GB but it's only 13GB. Very silly.


A lot of that is the XBox Operating System, I know I have one  :-)

Actually, the Amiga could access 879KB with FFS. 837 was the capacity with OFS. Bear in mind also that those floppy disks actually have a capacity of 1MB, and HD floppies have a 2MB capacity unformatted. PCs could use 720KB or 1.44MB of the HD types, Amigas could use 880Kb or 1.76MB. After that you have the overheads of disk.info files, volume information and other filesystem stuff taking up another KB or two...


You are indeed correct, it has been such a long time now that I used an Amiga properly yet Amiga.org is one of my most visited websites  :crazy:

Believe it or not it was as recently as 1997 that the most blank floppy disks were sold, the following year being overtaken by CD-Rs

I still use floppies fairly often, although that is no secret really  :lol:
