Minor problem with a portable drive (not showing full capacity)

[haaammit]

Hi - I have a Western Digital 250GB hard drive that I took out of a defunct laptop - bought a case (sata to usb) plugged in in, but the drive is only showing 232GB of space. I've tried formatting a few times, but the same thing keeps happening. I think when I first plugged it in, it showed as three drives

Can anyone help? Many thanks

/edit - I know it's only 18GB, but it's the principle

232GB as seen by Windows is correct.

HDD manufacturers use an SI measurement of GB which is 10^9 bytes.

Windows uses a binary system which is 2^30 bytes. Technically this is a Gibibyte.

250GB using the SI measurement is ~232.83 GB using the Windows binary system.

If the drive does have more than one partition on it then you need to delete all of them in Windows Disk Management and then format the drive as a single partition.

You still won't see more than 232GB though.

Ah - I see! Every day is a school day!

Many thanks
