Your 250 GB hard drive hasn't lost any space, it was always shown as 232 GB, you just didn't notice it before.

Hard drive manufacturers quote capacities in decimal (1GB = 1000 megabytes), whereas the "true" binary formula is 1GB = 1024 megabytes, and that is the formula that DOS and Windows uses.

For future reference, here's a formula you can use to calculate capacity:

Advertised capacity x 0.9313 = Actual capacity

I've never understood why HD manufacturers can get away with misquoting the true capacity but it seems they do.

Always pop back and let us know the outcome - thanks

"I've never understood why HD manufacturers can get away with misquoting the true capacity but it seems they do."

The problem is that it's always been that way, and no drive manufacturer wants to be the first to start labeling their drives with the true binary capacity because it would make their drives at first glance seem to be poor value for money compared to other brands.

They all need to get together and decide on a date for all of them to stop quoting decimal-based capacities on new drives, but since they are all competing against each other for market share, I can't see them doing that anytime soon.

The willingness to change a well-established custom just isn't there.

Yeah, just makes me wonder why it is legal tho. With most other things you buy the product has to be correctly described.

Try arguing in a court of law that as in computing a kilo = 1024 while in every other system of measurement a kilo = 1000.

As the man said once, "there are two kinds of people in this world, those that understand binary and those that don't. I suspect lawyers and marketeers fall into the latter category.

Actually, the man said, "There are 10 kinds of people in this world, those that understand binary and those that don't."
