Can My Book Essential be formatted for an IMAC

Hi,

I have recently purchases an IMAC and wondered if my hard drive can be formated to use with it. To prevent me buying another. 

I have a My Book Essential External Hard drive.

If It can be formated how do i do it?

Thanks

It can be reformatted for Mac but it will destroy any data on it. See if this helps  http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std_adp.php?p_faqid=3865
