brendankoch Posted May 14, 2006 Share Posted May 14, 2006 Hi, When I installed OS X on my computer it loaded the genericata driver and could not recognize the full size of the volumes. Like many other people my 200GB drive showed up as 128GB. Then when I got it to load the viaata driver it recognized the full capacity again. I would like to add the free space partition onto my 128GB one but the resizeVolume command won't work with the free space. Is there any way I can format the free space so that the resizeVolume command will work with it? Link to comment Share on other sites More sharing options...
brendankoch Posted May 14, 2006 Author Share Posted May 14, 2006 OK, I managed to format the freespace partition to HFS+ so now the resizeVolume command actually tries to resize the partition size but I get an error "Resizing encountered error Could not modify partition map (-9986) on disk disk0s1 Macintosh HD" Is there a solution or does that resize command just not work properly with hackintoshes?

jbellanca Posted July 28, 2007 Share Posted July 28, 2007 sorry for reviving this one, but i got the same problem here. any help? or any other way to increase the size of a HFS+-volume? I'm also having this problem... anyone have any ideas on stuff to try? Oddly, SuperDuper, CCC, and Hatchery H1 all crash also... these are my only problems with my hackintosh...

ryan0204 Posted August 3, 2007 Share Posted August 3, 2007 Having the same problem here. Finally got OSX to see the full drive but now I can't do anything with it in Disk Utility. I was able to format the unallocated space to Fat32 from windows with a program called Paragon Partition Manager. OSX can see the Fat32 partition now, but disk utility won't let me convert it to HFS+ Link to comment Share on other sites More sharing options...
Chris Emerson Posted May 21, 2010 Share Posted May 21, 2010 Same here! Tried many times over but I can't get past this dreaded "can't modify partition map" nonsense! Please some hackintosh expert come save us! Link to comment Share on other sites More sharing options...
srs5694 Posted May 28, 2010 Share Posted May 28, 2010 Does the disk use the Master Boot Record (MBR) or GUID Partition Table (GPT) format? Apple's Disk Utility can only resize HFS+ partitions on GPT disks; it can't resize partitions on MBR disks. If you've got such a disk, you could try Parted Magic or System Rescue CD. These are Linux-based emergency disks with a partitioning tool called GParted, which I think will resize HFS+, but I'm not positive of that. (If one tool doesn't work, try the other one; it's possible that one has HFS+ support but the other doesn't.) Another option would be to use my GPT fdisk to convert the disk from MBR to GPT form; however, Windows won't boot from GPT on BIOS-based computers, so if you've got a Windows dual-boot system, this may not be a good choice. You'll also probably have to reinstall your boot loader if you do an MBR-to-GPT conversion. Link to comment Share on other sites More sharing options...
