I bought an WD External Passport fro MC originally with 600GB size at Best Buy shop. used for a while and than tryed to reformat for using it with Mac and Windows. By asking my computer (windows based) to do that , it formatted to windows 7 format and maximun size of 320GB. Now I am not able to format the disk to his original size as at the MAC Disk utility I am not able to alter the 320GB pre set (by windows).
When you formatted did you delete the old partition first? See if this helps http://wdc.custhelp.com/cgi-bin/wdc.cfg/php/enduser/std_adp.php?p_faqid=3865 Partition isn’t always simple and most of us don’t do it very often.
Thnaks for your info, I have indeed formated all including the original partition and I am not able to return it to his original size as yet!
Any “magic” available or I have to get new files or drivers from WD?
