That seems about typical for a 250GB hard disk. The 250GB figure quoted is before the disk is formatted. I have 2 250GB disks and both show 232GB as being available.

My 200GB disk shows 189GB as being available.

Its partly the way manufacturers describe there hardware size they count base 10 computers count in binary.

Plus a little will be us to sore the master boot record when the drive is formatted.

Don't worry, there is nothing wrong. Hard drive manufacturers use multiples of 1000 when quoting drive capacities. Windows uses a binary thousand, 1024. 250.000.000.000 = 250GBs as quoted by drive manufacturers but = 232.83GBs as read by Windows. Both figures are correct.

It's not a con - it's the way things are counted.

The internationally accepted way of measuring 1000 of anything is Kilo. Thus K=1000.

Because of the way computers count, historically computers have used K=1024.

The drive manufacturers are absolutely correct in what they do - the confusion is ours.

If you look at the drive properties in Windows Open My Computer, right-click on the drive, click on Properties) you will see the capacity shown both ways as 232 GB and as 250,000,000,000 Bytes (approx - you usually get a few more).

so don't you think they should state on them "232gb of usable capacity" in stead of misleading people into thinking they are getting 250gb

Before you get angry, check the small print in the ads, they generally state something along the lines of "1gb = 1000,000,000 bytes"

You never get the full size of a HDD after format,i have a 160 gig drive and only get 149 after format,this is not uncommon with most drives.

1. You are getting 250GB of useable capacity - you do get 250,000,000,000 bytes - that is 250GB.

2. ACOLYTE - it's NOTHING to do with formatting - the capacity stated by manufacturers IS the formatted capacity.
