I have a 1TB external hard drive and I want to slice it into different partitions. When I try to do so, I get this error:
can not modify external drive because it uses master boot record
Is there a way to fix this without deleting the data that I have in it?
I have 700GB of data, and therefore I can not back it up; even when I try to compress it or make a dmg file in Disk Utility.
I have also tried to use the Disk Management on Windows 7 and still it does not allow me to shrink this.
Is there a way to shrink this partition without losing the data?
