Ok I just bought a Lacie D2 Big Disk 500 gig. When I first connected this to my iMac G5 it asked for updated drivers which I got from lacie site. Everything went fine till I started looking at the size of the drive. 239 gig total space which I know sometimes is reported wrong so I added 235 gigs of files to it and then started to add 9 more gigs to see what would happen to no avail I got the message the disk is full. So now can anyone recommend a good formating to gain my true space back? Disk utility even reports the tottal size of 239 gigs. Any help is greatly appreciated.
