Seagate 400 GB external HDD shows only 372 GB?

Yeah, it is kinda bad marketing, but in most cases they give the actual size of the hard drive under Windows XP somewhere in tiny print on the box. If it's OEM, then chances are it doesn't have it anywhere... Once terabytes become standard, you'll only be getting like 91 percent, so it's gonna get crazy after a few generations of hard drives. And just to clarify, nothing at all is wrong with your hard drive.

Sorry this situation happened. 372GB is still a ton of space though . Way more than I need, anyway.

you will never get the max coz some is lost from the formatting

It hasn't lost anything from formatting.

The usuall pure 400GB would equal to 409600000 bytes.
They use the 400GB as 400000000 bytes, which causes the size problem. It's common to all drives.

my 160gb one comes to around 150gb (my main hard disk, not external one)
