I have a 1TB My Book that was used on a PC until I bought an iMac. I hooked it into the back of the Mac and it seems to work. However, I get the impression that I need to reformat the drive for Mac OS.
Is it true that I need to reformat and then configure for the Mac?
What happens if i don’t (it seems to be working so far)?
I know everything will be wiped when/if I reformat the drive. Do I then have to download all the drivers, etc.?
Thanks for your help.
