OS X :: Partitioning With Disk Utility For Storage And Backup
Jun 25, 2009
Here's my setup:
One, dual bay enclosure (1.5TB x2):
OWC Mercury Elite - AL Pro Dual Bay Enclosure
https://eshop.macsales.com/item/Othe...ng/MEFW934AL2/
and one, two pack of 1.5TB Seagate HD
http://accessories.us.dell.com/sna/p...550055-683153-
Total: paid $310 including shipping for the 3.0TB external setup.
I'm going to use FW400(since my MB pro has no 800 port) and partition this into two 1.5TB partitions. one for storage, and one for time machine backup. My question is if I choose 2 partitions in disk utility, will it automatically know to use one of the 1.5TB Seagate HD for one partition and the other 1.5TB seagate for the 2nd partition? Or will it use half of one and half the other? I would like one partition to be one seagate 1.5TB HD, and the 2nd partition to be the other, that way if one fails I have a backup (using Time Machine with one partition to backup the other 1.5TB drive).
I have used bootcamp to partition my disk and install windows vista onto my uMB. Now I want to partition the disk again to create a tri boot setup where I can either install ubuntu or the dev preview of snow leopard (I haven't decided yet). Can I just do this with disk utility and shrink my OS X partition in order to create a new partition or will this cause problems with the disk? I would really like to not do a fresh install of OS X because I have had to do this twice to fix disk problems relating to bootcamp.
I currently have Leopard installed on my MBP. A while back I installed Windows XP Pro SP2 via bootcamp. I have a 130GB Leopard partition, and a 18GB Windows partition. Now I want to add another partition, splitting the Leopard partition into two. I want to add a 20GB partition. I have cleaned my computer, and there is plenty of free space to do this. Currently 70GB free. So I go into disk utility, and try to partition. Doesnt work. Says that it failed to verify, repair disk. Then i boot from Tiger install disk, open disk utility, and verify disk. Says there are errors so i repair disk. Says that it repair worked. Verified again just to be sure, no problems. Go back into leopard and disk utility to try and partition, still does not work, I get the same error.
I'm trying to restore the partitioning of my late 2011 Air drive, after messing it up while trying to dual boot OS X and Linux. The goal is to get rid of the superfluous partitions and resize the OS X one so I can use the whole drive again. Data loss is not an issue. According to Disk Utility the partitioning looks like this:Â
I was in the recovery hd, and i was partitioning my main drive into to partitions. while it was pertitioning, i accidently quit the disk utility. i saw that now the hd was in one partition and was nearly full (it was half filled before). i did a disk repair and it came back to half filled. now that i retry to partition it it gives me error Â
" Partition failed with the error:  Couldn’t modify partition map because file system verification failed."Â
Is there anything I can do except from reinstalling everything?
I have a hard drive with about 250 gb of film and music on fbut it's formatted as HFS+ which windows cant read! I need to partition the drive to make windows be able to read at least a portion of it. But If I run disk utility and create a partition will it erase the info I already have on there? I don't have this data else where so I hope it wont!
Issue - In the disk utility, the free space under partition and Macintosh HD do not reflect on each other. There is the difference of about 10GB between these two.
I am going away traveling and need to back up all my stuff off of my mac for the first time.. (pics, music etc the usual). I brought a WD Elements 500GB External Hard Drive and when I plug it into my mac book (OSx) it appears in finder, and the desktop but I can't drag and drop nothing into it. Apparently I have to format it! So have researched about formatting it, but I don't have "Disk Utility" in my utilities? My Mac was given to me from a friend second hand so i don't have the disks etc to get it. Any other way of formatting my Hard drive or a link to download disk utilities or any alternatives!
I'm trying to use Disk Utility to restore a .dmg backup file stored on an external usb hard drive. The image is a read-only dmg and is 75gb. When I try to restore the 75gb image to a 128gb SSD formatted in OS Extended (Journaled), Disk Utility says that there is not enough space on disk to restore.
I have to erase my HDD, due to a problem in the booting. It gets stuck at the grey logo screen. I�ve tried all possible solutions, but to no solution. So, i was wandering if it is possible to make a copy of some of my work files to an external hard drive trough Disk Utility, since my external HD doens't have enough space. Also, i�ve noticed that i only have acess to certain system files, trough the disk utility. No desktop folders or aplications.
Two days ago my computer died and I haven't been able to get past the Apple screen since. I've tried starting in Safe mode, etc. that did not work. I just started up using my installation disk and got into Disk Utility. It says it cannot repair the disk and that I should back up as many files as possible and reformat the disk. How am I supposed to back up if I can't start up? I am currently creating a new image of the HD to an external drive but my question is if Disk Utility couldn't repair the disk, with the external drive copy also be problematic? How can I tell before I reformat the whole thing and start over?
I would like to "Back-up", "Clone" or create an "Image" or whatever else people call it of my bootcamp installation. I know I can create an "Image" of bootcamp via disk utility but how would I restore it?
Would I first delete the bootcamp partition and then re-create a bootcamp partition and then restore? Or would I just restore? Will the end result be what I am expecting, i.e., my Win 7 install right back to the perfect state of when I created the image?
Right now, let's say my Windows 7 install got smoked one day for whatever reason (it is windows...) and I needed to re-install. Me personally, I would just go into Bootcamp Assistant, delete the Windows partition then create a new one and then get installing. Unfortunately installing and updating takes hours and that is what I am trying to avoid.
I keep getting this error..."The disk cannot be partitioned because some files cannot be moved. Back up disk use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."So I've checked and my HD is already a Mac OS Extended (Journaled) volume. I've gone to Disk Utility and verified the HD, verified permissions, and repaired permissions. I don't know what else to do. I don't want to backup the entire drive and format it.
Awhile back I bought a 500 GB Seagate FreeAgent Go external hard drive to backup my 218 GB PC. I used the automatic backup software that came with it and it works fine. After all this I purchased a MacBook Pro and now, instead of buying another drive and also considering there's plenty of space on the one I already have, I was wondering if I could possibly partition half the drive to be used as a backup with Time Machine without touching the other half. I plugged in the drive to my Mac and opened Disk Utility. It says it is a NTFS file system (I suppose that's normal).
I recently added a G-Speed Q RAID array to my MAC PRO to use exclusively for back-up with Time Machine.It worked great.I then decided to also share the external device over hardwire lan with my wife's iMAC so whe could back-up with Time MAchine as well.I then started reading posts that suggested the two Time Machine instances would compete for space on the back-up array and eventually it would fill up a I'd have problems. The solution, everyone said, was to partition the external drive and assign one to each Time Machine back-up.I did this and everything seemed to be working great until the remote client tried to run back-up.
It fails with the "Disk does not support AFP features" error message.Current status, local machine back-up works fine. Remote machine cand find the drive and connect once I provide correct user name and password, but fails once back-up begins.Both machines are running Lion 10.7.4.
it's that imac g3 again. I would like to know how to partition the hard drive without a bootable cd or any external drivesis it possible?ipartition (demo) says that I cant partition my hard drive if I boot off of it, but I have nothing else that I can boot off of.
I've been looking through Google for help on this but I'm really failing. I've been wanting to partition my startup disc on my Emac (which is running Tiger) so I can have a Panther partition and a Tiger partition. I have many reasons for doing so, but I don't really want to go through that right now.
I tried going to Disk Utility, but apparently, the startup disk cant be partitioned while I'm on it. I'm a new mac user, so I am having difficulty figuring out how to partition my 40GB harddrive to have one 10GB volume that Panther can go to. From what I hear, I have to partition using an OSX disc, and then reinstall Tiger and then I can install Panther. Please tell me there's a simpler way. I really don't want to go through reinstalling Tiger again.
I setup boot camp yesterday and it messed up, blue screen of death, unresponsive, etc. I deleted the partition and I tried making a new one. 40GB out of my 250GB (173 Free). I got a error that said i needed to restore my system, i do not have a external hard drive and i couldn't do that. Then i figured out what this error means:I read it has something to do with not having enough memory, where i have to defrag something, basically it was a long explanation but it made sense (I just deleted a 50GB file).So i was able to make a 5GB partition, and i'm like, "Ok, it works, ill try a 32". I tried a 32 partition and it just sits at "Partitioning Disk". If i open disk utility i can see
Disk utility doesn't seem too happy with adding a partition to my existing time machine disk. It has 750GB capacity, with over 200GB avail. I'm just trying to add a 70GB partition and it raises errors every time. I even tried using a mac that doesn't recognize it as a time machine disk, just a USB drive. Still no luck. I cant delete the data on this drive, so its important I just resize and partition without deleting. Any other options other than disk utility out there?
The title say it all, I've tried with my vista disc in the drive and out of the drive, given it a few goes for 10-20 minutes (recommended by people online) and then an hour just incase.
I recently decided to partition my hard drive on my macbook in order to install Windows 7, but upon doing so I was greeted with a message informing me that some files couldn't be moved and that I would have to reformat my HD. I created a backup disk image using disk utility and proceeded to erase and reinstall my OS. My OS is now reinstalled but I don't know how to go about using my backup to add all my old preferences, files, and applications. I've tried using restore through the disk utility but it isn't allowing me to do so. All I want are my old files and the ability to partition my drive!
After I erase the hard disk it shows 74.5gb free, almost. It says there is 42.3mb of space being used by 2 files which I understand are used for read write or partitioning or whatever.
When I then leave disk utility and go to the actual installer, the destination disk (untitled - 74.5gb) shows only 73.9gb free space. What is taking up an additional 500mb of space on the hard drive?
Apple support told me that somehow the disk has been altered and I lost space on the disk or I am now using a seperate partition that isn't showing up. Disk utility shows only one partition with 74.5gb free space. He told me I can find information about how to 'merge' the disk on the apple support section under troubleshooting articles for disk utility. I have been unable to locate this information.
I am trying to repair my disk so I can install bootcamp, but when I reboot my machine and run disk utility and choose repair disk, it hangs. Does anyone have any ideas ?
I have a 2TB Western Digital My Book Studio FW800 external that has 5 partitions, connected to my 2011 iMac. I had help doing the partitions and don't really remember the reasoning, but one is just for my SuperDuper! backup, one is Miscellaneous, one for movie clips off my camcorder, one for misc scanned photo's and one for my genealogy research. I back up using Time Machine to a Time Capsule and also to this WD hard drive with SuperDuper!Â
Recently I'm getting a pop up message that "Mac OS X can't repair the disk "Genealogy"'. And it needs to be reformatted. It's become a read only disk. When I look in Disk Utility it shows all the partitions as "Mac OS Extended (Journaled)" EXCEPT for the one in question. I also noticed that there are a lot of files with "date created" being the same date in 1969! These files may be letters I've written or photo's I added to that partition within the last few years.Â
I think I have to completely reformat the entire external hard drive to repair this, but I want to make sure. Because it's going to be a major hassle backing it all up to another external (having to get one first) and then figuring out how to make the files that have turned "read only" in that one partition, back to their original state!  Does this sound right, that I have to reformat the entire external hard drive? And how do I get the read-only files back to their original state.
I get this question mark along with a folder when starting up. I tried holding down the option key when turning on the power and then I get an internet recovery along with a globe. I click on the arrow below it and it takes maybe 15 minutes to start up. Then i get this disk utilities screen. I'm now unable to do anything. When going into disk utility, disk 0 shows with Mac OS X base system underneath it. All the clickable buttons are faded out. Is there something wrong with the hardrive? and where could i get this fixed? There isn't a warranty on it.
Running Diks Util on my iMac 10.6.2. i am given this warning. ========= Warning: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent" has been modified and will not be repaired.
Is it something I should heed and what to do in that case?
I had windows vista installed but suddenly the audio decided to become faulty, after spending a day trying to fix it i realized I have a windows 7 install disc so i might as well just replace vista with windows 7. I didnt take care of vista or ever register it so it became quite a task to upgrade so i just deleted the partition and went to create a new one and just do a full install of windows 7.
I made the partition but the wrong format, so i removed it through boot camp assistant and created another, except now it keeps giving me the "back up the disk and use disk utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using boot camp assistant again" Now, I'd love to do this, except I have no idea what I'm doing and WHY this error has occured. After becoming frustrated I switched from my imac to my macbook pro and received the same error when trying to create a partition. So any help on exactly what I need to do would be a HUGE help. I only use windows for music production (I know, seems backwards, but I use Sony Acid and FL Studio so I'm stuck with Windows)
I'm trying to repair my hard drive. I restarted from the OS X Mac Mini install CD (holding down the letter C when I heard the chime), opened Disk Utility from the Utilities folder, selected my hard drive image, but the "verify disk" and "repair disk" options are grayed out. I'm at a loss as to how to proceed.
