Resize partitions

[allosunshine]

I currently have my MBP HDD partition into to 2 where one is my System and the other Filestore.
Can I safely shrink the second partition and increase the first partition using the built in Disk Utility without erasing any data??

Cheers in advance.

I think you can yeah, just drag the sliders and click Apply. If it does want to erase the partitions, it will come up with a dialog warning you that it wants to format it.

Are the partitions of the same filesystem? e.g. HFS+

If so, it should be a simple case of pulling sliders

Having tried using Disk Utility, I could resize my second Filestore partition no problem but it would not let me resize the first System partition to use the space that I had free'd up.
Gonna try doing it from the Boot CD, see if it works that way.

Tried using Disk Utility from the boot disc and still no joy. Looks like a third party app it is then.

It is possible your disk just lacks contigious space to allow re-sizing.

Do a defrag and try again. Had this issue when trying to resize for bootcamp.

If you want a free defrag - just back up your primary partition to an external then restore it back to the internal. This writes the files in a nearl contigious block allowing Disk Utility to go about its work without pussyfooting around scattered files.
