Look on the Hitachi web site for their disk management and repair tool and use it to check your HDD. If by chance your HDD does not have its SMART function activated, you can use such a tool to do so. SMART should also be activated in your BIOS.
A quick search gave me this as a starting point. There is a bootable CD.
If you need to do things the hard way, you can find bootable floppy disks from bootdisk.com, among others, as well as use a FreeDos alternative. If you do not have a floppy drive, and need the function, Google will show that it is possible to burn a CD in such a way that it will imitate a 1.44MB floppy disk.
As an example for the next time, remember that it would have been more useful if you had specified the model number of your HDD. The Hitachi link included may or may not apply to you, but that is not clear without more information.
