I have Vista and Leopard on a Macbook Pro and want to change the size of the Vista partition. I bought iPartition, created a boot dvd disk, ran the application and the partition failed. I then bought DiskWarrior, ran the application, it found a few errors and corrected them. I ran iPartition again, same error. I have a160GB hard drive, 32GB dedicated to Vista using bootcamp and want to increase the partition to 100GB. iPartition alows me to change the sizes of the partitions but after it analyzes the data I get the following error: hfs_extent.c:676 (from 0x1000ad6c9)65) unable to locate extent for file 1597906 (resource fork? 0, start block 26652804, length 1, itterator error0, btree error 0) I'm not a computer guy, anyone know what the heck i can do????
