OK, this isn't too bad. Reboot while holding Command ⌘-S to enter single user mode. When it gives you a prompt, type fsck -fy then press return. it will repair your disk. When it's done, type reboot and try partitioning again.

The best way to do this is probably to setup /Users as an automounted partition, with all your home directories in the root of that partition. I am going to assume you have already copied over the home directories properly (with permissions enabled). Now you just need to add the volume to /etc/fstab. Assuming the parition is named Users, you add a line like ...

Looks like your MacSSD2 partition has been turned into a Core Storage volume. Core Storage is Apple's underlying system for disk encryption - I assume you enabled encryption when you created the partition? You can show the Core Storage volume group using the command diskutil cs list and then delete it using diskutil cs delete <volumegroup-uuid>, where ...

For free, you can use the NTFS-3G driver. In order to use it, you have to install MacFUSE first. In the end, you'll have a prefpane to mount and manage your NTFS drives

Yes. You'll need to create a file called "fstab" in /etc if it is not already there: sudo nano /etc/fstab Next, we'll need the partitions Unique Universal Identifier (UUID). Open Disk Utility, and highlight the partition you'd like to no have auto-mounted. Then hit CMD+I and you'll be greeted with the following screen (notice the UUID highlighted): We ...

Ok, this is written for a 500GB HDD. 4 partitions max, just like every other (bootable) hard-drive. I tried this on 2 MacBook Pros and it works perfectly on both. This tutorial also assumes you have OS X Lion installed. What I want to achieve is to have OS X Lion & Windows 7 installed, with a shared space too. 120 (OSX) 260 (SHARED) 120 (Windows) ...

You can recreate the EFI System Partition (ESP) using the command-line gpt tool. It should start at sector 40, and it should be 409600 sectors (exactly 200MiB) long. The GPT entry's type should be C12A7328-F81F-11D2-BA4B-00A0C93EC93B, and if you have a hybrid MBR, the type there should be EE. The format is actually a subset of FAT, not HFS+. You can read the ...

I’ve not tried MBR1… but: you can indeed boot Windows 7 and Windows 8 (64-bit versions) in EFI mode off of a Thunderbolt-connected disk. I have a handful of the Buffalo Ministation Thunderbolt2 drives with the original, slow 5400 rpm hard drives replaced with various SSDs, and they work wonderfully3. You can boot off of them by pressing Option during the ...

This is an older post, but I came across it today and figured I'd share what I found. The 'bless' command seems to make this work. First make sure the disk is mounted, find out which folder it is mounted to, and: sudo bless --folder <mount_path> -label <desired_label> For example: sudo bless --folder "/Volumes/Mac OS X Lion Install ESD" ...

It's rather complicated, and actually a lot of the complexity is to avoid wasting space; I don't think you can "reclaim" anything without breaking it. Let me start at the beginning: your hard drive (/dev/disk0) has two relevant partitions: Macintosh HD (your regular startup volume), and Recovery HD. Recovery HD is marked in the partition table with the ...

You can use GParted to achieve this, as it supports HFS+, FAT32 & NTFS resizing.

Here is my recipe for a Successful setup of OS X Lion + Bootcamp Windows 7 Ult + Data Partition Ok, so after many, many hours I think I've finally figured out how to successfully install Mac OS X Lion with Windows 7 on a Bootcamp partition AND an 3rd data partition. Here is a screenshot of my setup on my 13" MacBook Pro as it looks at the end of the ...

This is entirely possible. I use either of both of the following variants depending on what I'm trying to test: Virtual machines You can run OS X 10.7 and newer inside recent versions of Parallels and VMWare Fusion. You can also run the server variants of older OS X versions this way; these older server variants also work on VirtualBox, which is free for ...

Quick and Simple: Since it's a GPT disk you can run gpart recover /dev/disk1 to fix the table. You blew away the first ~700MB of the drive, so any partitions touching that area are gone too (more or less). The rest of the disk should be fine. I'm not sure if OSX comes with gpart, so you may need to download it somewhere. The longer details: Concerning the ...

If I understand your question correctly you are trying to resize the volume group or actually one of the volumes within a group. From what I could gather your disk was converted to a CoreStorage Volume. Could you please verify that by issuing the following command in a terminal and check if you get a similar output to the one in the picture: diskutil ...

Short Answer: YES, it's reversible, nothing is "permanent" in a hard-drive partition (other than deleting partitions and information of course). Almost always you will be able to undo what you did, although sometimes at the cost of data loss, naturally. While you are at the terminal type: man bless or if you're lazy, you can read it here. You are ...

Sorry but there is no way to reformat a Hard Drive while keeping the current data intact. You can either move the data off, reformat to HFS+ then move the data back on or add a second partition that is HFS+, move the data to that partition then remove the old NTFS partition and expand the HFS+ one.

Here is my current solution: boot from OS X DVD - mandatory! open terminal diskutil list umount "/Volumes/Macintosh HD" fsck -f /dev/disk0s2 diskutil resizevolume /dev/disk0s2 100G

diskutil list In my case I wanted to format the parition as NTFS for installing Windows 7 on it. The last parameter is the partition 4 on first disk. diskutil eraseVolume "Tuxera NTFS" my-ntfs disk0s4

I payed(34$) for the full NTFS driver from Tuxera, the free version was not able to safely eject NTFS disks. Update: starting with Lion, you'll not be able to share the NTFS drives even if you use NTFS-3G or Tuxera NTFS for Mac. It may be a good idea to reformat your drive to EXFAT in order to overcome these issues. I know it's a real pain and time killer. ...

You can't change where each partition starts (i.e. where the top of it is in the partition diagram), only where it ends. But in your case, since you have a free block as large as the partition you want to change, you can work around it (warning, this is untested under Lion, so make sure you have a good backup first): Create a new volume in the blank space ...

Time machine doesn't care what else is on the destination drive as long as the volume (partition) you choose meets the minimum requirements. If the volume you select isn't formatted properly, Time Machine will offer to erase and reformat the part of the drive that will contain your backups. You might want to try resizing partitions using whatever tool you ...

Just move them is probably the best solution. The user caches and preference files stick with the user home folder, so other than convention - most cases it doesn't really matter which volume contains an application. You'll need sudo or file permission tweaking to actually delete some of the apps, but I've found no downsides to moving any apps to an external ...

iPartition For all my partitioning, I use and recommend iPartition. It will allow you to resize partitions without deleting any data. It also works for Boot Camp volumes and other PC disks. With iPartition, resizing a partition is as simple as selecting it, grabbing the resize handle and dragging. Not only that, but if you have several operations to ...

This is how to fix the bootcamp windows install error: "Windows could not update the computer's boot configuration." Do not try to fix with a workaround - you'll find solutions of people manually selecting their Windows partition during reboot by holding down the OPTION key. This will work, but you are circumventing the way that apple wanted you to install ...

(Before proceeding, please make sure the disk in question is still disk2, you have backups of your data, etc. - that said, the changes here are not particularly dangerous. Read through the whole instructions before doing anything to make sure you understand all the steps.) OK, your partition tables look fine (a valid GPT and a correct protective MBR), so I ...

Mounting the volume Disk Utility verification and possible repair of the partition map If you have not already done so, use Disk Utility 13 (426) in OS X 10.8 to select then verify: not the greyed-out partition instead, the physical disk that contains the partition. If verification reveals a problem with the partition map, then consider allowing Disk ...

According to your output, you copied 645MB to disk, which means the EFI and first ~440MB of the Linux partition were overwritten. Your Backup and Misc partitions were not modified, so the data in them can be recovered... if you can find them. This may be relatively easy1. GUID partition tables are stored at both the beginning and end of the drive, so as ...

A maximum of sixteen partitions per GPT disk may be for one or both of the following: compatibility with other BSD variants UNIX certification/conformance. Key points In theory, a GUID Partition Table (GPT) disk can have an unlimited number of partitions. A Microsoft implementation of GPT allows a maximum of 128 partitions. The OS X kernel, ...

Disk Utility doesn't resize FAT or ExFAT partitions on the fly, so you will need to take that drive to a Windows or UNIX computer or use another tool to resize FAT. If you only have Disk Utility, I would create a dmg of the FAT partition and save it to the main partition. Then you could delete the FAT partition, resize the HFS partition and recreate the ...
