OS X :: Partition Map Scheme ?
Dec 17, 2009
I don't know how I managed to do it, but I'm running Leopard on my MBP on an Apple Partition Map. Anyhow, I got my Snow Leopard disk yesterday and it wants me to reformat to GUID and warns me that it will erase everything. Now I have to figure out how a way to backup everything, install SL on GUID and restore everything while retaining my settings, serial numbers and all that good stuff. Is this possible?

I'm trying to set up a new partition scheme for all my storage. I just purchased another drive and will buy a 1 or 1.5TB drive next week. I'd like to encrypt certain partitions. Please read on...
Hopefully someone can help me. This is my current setup:
Filesystem Size Used Avail Capacity Mounted on
/dev/disk0s2 465Gi 407Gi 58Gi 88% /
devfs 113Ki 113Ki 0Bi 100% /dev
Plato is my iPod - I use 40GB for music, the rest for backing up files.
Wittgenstein is my backup. I exclude backups of ~/Music, another big DIR and ~/Movies and it has room to backup everything else.
I also have an 8GB USB stick that I've named "mnemosyne".
What I am purchasing. I am waiting for my new 500GB 7200 drive to arrive, which will replace the current 500GB main drive. I also purchased a 32GB flash drive.
What I'm getting in the near future. I'm purchasing a 1TB or 1.5TB internal drive and building an external HDD from it within the next two weeks. I'd like to split it to 500GB for backups, the rest for media storage. I'd like to encrypt my current /System dir, my ~/Documents and all preferences from my my Applications.
I've heard filevault is prone to errors. Is this true? Are there any other full disk encryption options for mac? Would dm-crypt work through macports without corrupting my filesystem? Can I use truecrypt and create an encrypted container of say (what is now) ~/Documents
Creating the partition scheme
Questions
1) Can I resize a partition once I've created it if there's physical space left on the HDD?
2) Should I leave some space without a partition? Or should I just name it something benign and use it as a "dropbox"
3) What options do I have for encryption on a mac?
4) Is filevault prone to errors? Any benchmarking tests out there?
5) Can I use dm-crypt through macports and have a FDE setup that won't fail because it's through macports and not native? In other words, I realize all encryption schemes can fail, but I'd like to minimize risk.
6) How would I have some movies on my main HDD and others on the external volume? Is that possible? Or would I need to create two partitions for that? So, say, I want to store 40GB of everything that is currently in ~/Movies on my main HDD. Just create a partition for that, and then another partition on the external volume at 210GB?
7) How do I create separate partitions in mac?
8) How do I easily mount all partitions from all hard drives?
9) Is rsync and a script my best option for encrypting backups since Timemachine has no security whatsoever for backups?
10) What filesystem should I use? (I'm only using OS X on my macbook)
11) Any sample partition map you could share with me that will help me build this properly?
12) How do I set up a link so Mac OS X will read the partitions like they are now and display over on the left side of Finder.app as they show now? I.e. a list of Desktop, $username, Applications, Documents, Movies, Music, Pictures

So much for upgrading... Does anyone have a fix for not having a GUID partition table scheme? I was hoping I wouldn't have clean install, I just got everything how I wanted it. *sigh*
Something tells me there's no way around this.

I reinstalled Snow Leopard on a new volume, transferred stuff I wanted from the old volume to the new volume, and deleted the old one. In disk utility, I have not been able to stretch the volume to fit where the old one was. I can't change the volume scheme. Has anyone got a method to let me use my full 160GB hard drive rather than half of it? Or maybe software that can alter it.

I want to delete a partition and create a new one, but I need to be able to click option in able to do this. For whatever reason, disk utility will not let me edit my external in any way without deleting the whole thing which I do not want to do.

I have a 1 TB LaCie drive that I am currently using with a MBR partition scheme. It has two partitions: one for time machine and one for windows. What I want is to use this drive to hold my time machine back ups in one partition for Lion, which I am about to switch to and install on the iMac internal drive, my windows stuff in one partition, and a third partition in which I would put a clone (CCC) of my current internal drive (Snow Leopard) that I could boot from when desired.
This would enable me to run Lion normally from the iMac's internal drive, switch to the windows partition (holding down the option key when powering on) on occasion when I want to work in a windows only app, and using the same option key on power on trick, boot into Snow Leopard when I need to use old, apps that won't run on Lion. For this, I assume that I should use the GUID partition scheme. Am I right? Is there a better way to accomplish my goal?

iMac, Mac OS X (10.6.8)

for only one user on the system, the colour scheme has gone negative. Backgrounds, files, programs, etc. have all been affected. I can't find anywhere that would have this effect - it's not in system preferences or anything like. How can I fix this?

I have some things I want to keep very safe. It is not pornography (i.e. kiddie porn), nor is it illegally downloaded media files.
Imagine if I had caught a local official doing something in public that was extremely bad, and I wanted to release the pictures anonymously to our local paper and did not want the police to seize my computer and prove it was me. This is not the situation, but it is the type of stuff I want to keep extremely safe.

I've downloaded Lion and the first "complaint" the installation software has is that neither my Mac hard drive nor Time Machine drive uses the GUID partition scheme. The software instructs me to use Disk Utility to select the appropriate format but Disk Utility states that I can't re-size the partition because it uses the Master Boot Record scheme. Further, it tells me that the drive can't be erased because it's the start-up disk.
I have Snow Leopard 10.6.8 installed on my MacBook (Core 2 Duo, 4 GB). The Mac HD has 220GB available.I waited for Lion to be reasonably fault-free and carefully looked at Lion's requirements only to find out too late about this GUID scheme business. I haven't seen anything about this requirement until I tried to install. I have great fear of re-formatting the drive as that always seems to be the beginning of many problems that take months to resolve. Maybe the choices are to forget Lion or get a new drive and format it to GUID before restoring from my Time Machine

After updating to 10.1.2 it seems that FCPX now uses a different file naming scheme on imported AVCHD files. Â
Previously on import, it would use a file naming scheme based on date ie. '2014-06-14 10_49_47 (id).mov' etc. which is great for me as I could see exactly what date & time that clip was created at a glance in the event viewer, also when a camera on a shoot had it's time out by an hour due to an incorrect daylight saving setting, I could use easily go through the clips tweaking the time in the file name & then they would show in the correct order in FCPX.Â
Now 10.1.2 just imports the clips using the useless file naming scheme of 'clip #1.mov' etc ...
Any way to get FCPX to import using the old naming scheme - or am I now boned if I have a camera set incorrectly ...

Hopefully Apple will say no to this scheme of paying twice for the same CPU.See: http://www.boingboing.net/2010/09/19...-crippled.html

I recently made a clone of my Windows XP Pro SP3 installation (its roughly about 14GB according to Finder/WinClone) so i made a 80GB partition on my 320GB drive and it gives me this error message:
the WinClone came from a 500GB internal drive and ive gotten winclone images to restore to a MBP before but not sure why its giving me this error code, anyway to restore the image to the new partition (which was created with Bootcamp) as i no longer have access to the old machine it was running on.

First some background info. I recently purchased a 1TB hard drive for my 13" MBP, and I am about to do a clean install of OSX 10.6 and Win7 64bit on separate partitions.
And I want to setup the partitions before I install using Disk Utility. The reason for this is because I'm under the assumption that when creating a NTFS partition its better for the disk to be blank so it can put the MFT(Master file table) and MFT Mirror wherever it wants instead of some random spot on the disk (that way disk writes will be faster). The MFT thing was true when converting a FAT32 disk to NTFS. Nativity formatted NTFS disks were always faster then ones converted from FAT32, because the MFT was spread out instead of at the start of the disk.
I'm worried that installing OSX and then using the bootcamp utility will cause the MFT on my NTFS partition to end up in a un-optimal place and disk Reads/Writes will be slower.
Ok, so here's my questions.
1.) Should I be using a GUID Partition Table or Master Boot Record(Remember OSX 10.6 and Win7)?
2.) Should I use Disk Utility to Create a the OSX partition and then leave the second partition as Free Space? / Or should I use a third party utility and make the OSX partition and the NTFS partition at the same time?
3.) If I do create the partitions Manualy, will bootcamp still work correctly?
4.) Should I Use Journaled or Case-Sensitive Journaled on my OSX partition?
I know all of the questions were stupid, but there isn't any info on the web about it.

So my iMac came with a 1TB hard drive and I installed Windows 7 x64 but only gave it some 93GB. I have a two-prong question:
Can I add a third partition to my drive after I partition for BootCamp? My main partition ("Macintosh HD" by default) is over 900GB large and I'd really like to cut that up into 2x450GB, for example, in addition to the 93GB BootCamp partition.
Second, once partitioned, is it possible to resize the BootCamp partition to make it bigger after it has been set up?

Got my first MacBook Pro about 2 months ago and I have been enjoying it to full effect, installing programs such as logic studio and photoshop cs5 on it. Recently, however, I decided that I would like to access some of my windows based programs when I am on the road and don't have my desktop pc with me. So I bought a fresh copy of 32-bit Windows 7 Ultimate and sat at my macbook, put the disc in and then loaded up Boot Camp. I went through the menu options, decided that I wanted a 50GB partition, leaving my Mac OS drive at 182 GB with 83GB to spare. However, when I started partitioning, after about a minute it stopped and this error message appeared: "The startup disk cannot be partitioned or restored to a single partition. The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.".
I tried cleaning all my temporary files and deleting some files in my downloads that were quite large and I restarted my machine. The problem persisted. Is there a solution to this problem that does not involve doing all this rubbish with a fresh install of Mac OS? I don't have any method of backup apart from a couple of 4GB flash drives..

Partition failed with the error:
Could not modify partition map because filesystem verification failed
^ My windows bootcamp messed up so I deleted it and tried to install a new one but I get this message. Does this mean that there is something wrong with the hard drive?

I have just recently deleted my Bootcamp partition in Disk Utilities, and now im trying to increase the partition size of my Macintosh HD drive. When i go to the partition map and try to increase the size. The same error always appears. "Could not modify partition map because filesystem verification failed" I have attached an Image of what my partition map looks like right now.

I recently installed MacDrive on my Windows Vista X64 partition so that I could access my iTunes Library on my Mac partition. After installing iTunes on my Windows partition and pressing shift while it opened, iTunes asked me for an iTunes library file ending with the extension ".itl". Now, I do not have any files ending with this extension in my iTunes folder on my Mac partition. Is there anything I can do to make iTunes on Windows to read my music library on my Mac partition?

I am dual booting XP Pro and OS X on my NC10. I have XP Pro installed on the main partition with a FAT32 partition for files that can be read by both OSes (see attached image for two views of the partitions). I then installed OS X on an extended partition. Unfortunately, I had another 5GB partition also on that extended partition. I now want to delete the spare 5GB partition and non-destructively reallocate the space for the OS X partition - I want to expand it to be one big partition with my bootable OS X install still on it. Unfortunately, I can't find any way to do this in Partition Magic. Is it possible with GParted/BootItNG/iPartition or any similar software? If so, which and how? The NC10 has no CD drive so solutions that work from OS X or XP or a bootable USB stick would be preferred.

could not modify partition map because filesystem verification failed" I am trying to partition my hard drive to set up an XP system on it (I know, but it is for AutoCAD, sorry). Anyways, when I go into disk utility, and try to set up the partition, it fails. I have a newer uMBP, 375 free GB (trying to set up a 75 GB partition) and it just wont work. Weird. Nothing seems to be online about the problem.

I recently bought my mother a Macbook. It was a store display one but she had no problems with that. Anyways when we first boot it up I noticed that on the desktop there is a Time Machine disk. So I openMacintosh HD that there is only 17 gbs free out of 33 gb, so I check System Profiler to see if there is a smaller hd in there but the it says that the hd is 150 gb.
So I'm wondering how to delete the time machine partition and resize the Macintosh HD partition so I can give her the most space she can get.

I have a 13" MBP with a 250 gb hd, I partitioned the HD 25gb for Windows XP shortly after I bought it. I was unable to install my copy of windows, contacted apple after exhaustive search as to why... Long story short, I now have Vista to install... When I went back to Boot Camp Assistant; partition was gone. Researched... ran disk utility, repaired and erased partition. Bootcamp HD now shows up in desktop, still not in bootcamp assistant. Since I am unable to locate in assistant; would there be any problems with just installing Vista off the install disk by restarting? Any ideas what to do if this is not a good idea (short of restoring)?

Is it possible to sync one's OS X iTunes library across Boot Camp into Windows? I would like to have the same library on both my Windows and OS X partition, and by library I mean having the same ratings and play counts across both partitions in addition to the actual music. If this is possible, how can it be done?

I am trying to format my external drive to have (2) partitions. A NTFS for backing up my Windows computer and a HFS for backing up my MacBook Pro.
This is what ive tried:
1.) Create 2 partitions on my Mac in Disk Utility. 1 partition HFS, 1 partition FAT32. After doing this both show up in OSX but neither one shows up in WinXP. I was hoping the FAT32 would show up in WinXP so I can convert it to NTFS.
2.) Create 2 partitions in WinXP using Disk Management. 1 partition is NTFS and 1 is FAT32. Connected the drive to my MBP and both partitions mounted in Finder. I then opened Disk Utility and tried to "Erase" the FAT32 partition to HFS. The process seemed to be working but then it changed the name of the partition to disk1s1 and nothing else. The partition doesnt mount in Finder or WinXP.
3.) Create 2 partitions in WinXP using Disk Managment. Both partitions as NTFS. Connected to MBP and both partitions mounted in Finder. Opened Disk Utility and tried to "Erase" one of the NTFS systems to HFS. Same thing happen as #2, renamed the partition but didnt do anything else. The partition doesnt show up in Finder or WinXP.

I had my hard drive partitioned into 2, where one was mac the other windows xp. I received this macbook as a gift from my sister so i wanted to reformat everything into mac. I popped in the Mac OS x install cd and just installed it. Now there is two hard drives and I am not able to re-partition it where i can bring it back to one again...I was suppose to delete windows first before re-formating my macbook.
