Then you just delete the volume and the group that was created when Diskutil did the bad 'erase' - when you do that, your drive will be left with a single large partition and you just don't use Erase after that - use Partition in Diskutil and you'll be all set.īE WARNED - if you have a fusion drive, this will also show up as a Logical Volume Group and you need to make sure you're picking the right ones or you'll have serious data loss. Is that a pro…įirst run diskutil cs list to get the UDID of the volume group and the logical volume. Re: Disk Utility defaulted to Logical Volume Group format for new 4TB HDD and won't let me change to GUID. SnipperJS did the research and posted the solution on this thread: But when I select the mac partition in disk utility, Im not given the option to resize. Open Disk Utility and select the hard drive with the partitions you wish to resize. (the partitions appear as separate disks in the side bar) Any help is appreciated. Setup bootcamp to run Windows and Id like to increase the size of the bootcamp partition and reduce the size of the mac partition. You can resize the partition on macOS using Disk Utility.
Any ideas on how to rectify this? I am cool with wiping out the entire 3tb and having a fresh HDD, but it won't let me. I don't have anything important left on either of the partitions, (I copied the contents to other disks) I'd just like to get a single 3 TB disk back, but I can't resize the current partitions, so I am a little nervous.
So here's the deal, I think that I might have gone about deleting partitions wrong, now even though my laptop partition is 500GB, and the original storage was 1.85, I can't resize those to use up the full 3TB of space. Last night, I deleted the two partitions for other peoples computers, so now, I just have the storage partition, (called "3TB") and the partition for my laptop (called "Merrell"). Each of these partitions occupy precious space, which can be considered a potential partition volume to delete and therefore store other files on. Basically, at one point I had this broken up into about 4 different partitions one for each computer backup (mom's laptop, my sisters macbook, my macbook etc) and then one for random storage. However, in rare cases, the utility might not be as.
One of the HDDs in it is a 3TB WD Red drive. Mac OS X has a pretty solid disk utility for scenarios where you might want to create, resize or delete or modify new or existing partitions. With previous versions of Disk Utility, you could create multiple Partitions within a single physical disk, allowing. I have a mac pro 1 1 in my basement running as a backup server, central media location, etc. All I did was open Disk Utility, choose my HD, click partition on the tab on the right, click the plus sign, resize it to 50 GB and then click apply. Disk Utility separates the partition into two and moves the data from that partition on one of the new partitions. Hey guys, I think that I've done it this time.
