Welcome to Just Answer.The simplest way would be to connect it to a Mac and run Disk Utility, located in Applications->Utilities. It will allow you to reformat it to "Mac OS Extended".
"Mac OS Extended (Journaled)" should be the Volume Format option in Disk Utility.
ok I will try this
ok got to disk utility... what next? erase?
Click on the Lacie drive and go to the Erase tab.
Make sure it shows "Mac OS Extended (Journaled)" as the volume format, then click Erase.
(The Erase button.)
do i want time machine?
dont answer... I don't
Yeah, unless you're planning to use it with Time Machine only, you wouldn't want it.
ok now what? is it done?
If it finished, yes, it should be usable now. Go to Finder and make sure it shows up as an available drive.
it shows on the desktop I will eject it and connect it to my PC and see if macdrive sees it
Thanks sorry for such a stupid question...
