I have a LaCie d2 160GB hard drive hooked up via FW800 to my PowerBook and I've decided to resize some of the partitions on the drive. I've done this before without troubles, and running Verify/Repair Disk on the drive reports no errors, but when I go to resize any of the partitions on the drive, I get the following error:
What does this mean? Is there anything I can do to avoid formatting the drive? One of the partitions is my Time Machine backup drive and I don't want to have to format that.
Thanks for any help.
