Partiton, reformat?
Is it possible to create a partition on an external hard drive without wiping any data and then reformat that partition to Mac OS without wiping data on the unpartitioned space?
The external hard drive is USB 2.0, and currently formatted as FAT.
Thanks in advance!
There are no free ones, iPartition is the cheapest. If you want free you need to backup all info, re-partition with Disk Utility, which will erase the drive, then copy everything back. I don't think DU will do FAT formating either so you can't do it if you need that. If you don't need that then you should repartition into a Mac format.

After reformat everything went downhill.
Late 2011 Macbook pro
my HD only shows 370 gigs avail of the 500g hdd also failing to download and install OS back. It gets to just over 25% of the download then time doubles and shortly after that It says cannot download. I have tried on 2 different internet connections.
So I ran into an issue w/ parallels and some other software and had a nightmare sorting it all out. So I did a boot into disk utility and whipped everything clear, reformat everything to factory, removed bootcamp ect. Left w/ the recovery partiton and the macHD that is all. Now unless I did something wrong I seem to be missing a big chunk of space into a vast void. 100gigs seem to be gone. I have looked at the partitions to make sure nothing was missed, I even reformat everything again.
Anyways I figured well let me get the os back on here and go from there. So I start to install OS back on. When I first start the download everything seems okay, says it will take 25 mins (50 meg connection at home). When I get to 25% (just guessing), the time goes up to 1 hour, then to 3... I figured okay no big deal. Now around 35% It stops and says it cannot download.
I have to now start over. I did, and bam samething... Well thinking maybe its my connection, I take a buddies place and try on his internet.. Same thing......
Now im several hours into this and still not able to get my OS back on.
So I guess 2 major questions, well 3.
1. I dont remember if this Macbook came w/ a restore disk ( I norm keep everything in the box, no disk)
2. The Hdd reading only 370 gigs, is this normal? Seems like I lost 100 gigs somewhere. I do know when I was using bootcamp It said I had 80 something gigs partioned for that, then I removed/ reformat that partion, didnt see my "Macintosh HD" go up any.
3. If not able to download this and keeps failing (trying again this morning) what options do I have?After spending all morning working on this I cant get it to load from any connection. I made an apt w/ the Genius bar. I ahve never worked w/ them before so I dont know what to really expect. I have a bad feeling they are going to pitch buying the recovery thumbdrive off them. 70 bucks I dont have atm

My Ipod started making the frowny face at me and telling me to go to support, I plugged it in to my PC and was told that the device needed to be reformatted. I attempted to do so, the quick format fails right away, and when I try to do a regular format, i get the same message after a longer wait; "windows is unable to complete the format". Has anyone encountered this before, any suggestions?
ThanksCheck your Hardisk, using Disk diagnostic, posted by tt2, it will tell you if your hardisk need to replaced
There are some 3rd party hardisk repairs, which you can try.like EaseUS partiton. -
Unable to reformat my boot partition when booted into recovery
I need to reformat my Mac OS X partition for a clean install and when I boot into the recovery partition to do so I am unable to erase the partition. Some times in disk utility it shows as greyed out (unmounted) and will not allow me to mount. Then other times it will show mounted and I will be unable to unmount and erase. Any body dealt with this before. Help is much appreciated.
JHi,
So I tried to reformat with the SL disk in and I was given the error. This operation requires an umounted disk. Now the Disk is mounted but the Mac OS X partition that I want to erase is mounted I think. Is the way around that to unmount the entire disk and then try erase the partiton? I have a Bootcamp partition with a lot of university work and programming programs etc so I would really like to avoid an entire disk reformat.
Thanks again,

Create Boot camp partition on multiple partitions disk without reformatting
Hi everybody,
I am trying to install Windows 7 on a multiple partitions 1TB disk.
Currently I have 2 partitons:
300GB - OS X Lion
700GB - Data
I have read some tips and advices on how to install windows on multiple partitons disks - most of them are invasive (backing up to a removable drive and then reformatting). However, I haven’t found conclusive answer (hence my posting here):
I’m wondering does anybody know in any way - is it possible to do this more painlelssly - to divide second partition (or maybe first) and use that one as a bootcamp target?
Or am I stuck with reformatting to a single partition and then installing from scratch?
Thank you.No. To use Boot Camp Assistant your drive must start with a single volume encompassing the entire drive - one partition. BCA will then create a second partition for Windows and modify the bootloader so you can select which volume to use for startup - OS X or Windows. BCA can also remove the Windows volume and restore the drive to its original state - single OS X partition.
If you have more than one partition already then BCA cannot modify it. If you have a drive configured with BCA and subsequently add a third partition then BCA is no longer able to manage the drive, and you may no longer be able to boot Windows because of changes made to the bootloader.
So, yes, you are stuck with "reformatting to a single partition and then installing from scratch."
Your alternative is to create however many partitions you want. Install Windows on one of them. Download rEFIt to replace the standard bootloader so you can select between Windows and OS X (or any other OSes you install.) -
How to reformat Ipod Nano 5th gen when not recognized by Windows or iTunes?
I've done all the steps on the site to correct this problem up until the reformatiing part except I tried to update the driver software but Windows says that it encounters an error when trying to install the new software.
So after going through the steps I noticed that the iPod I just bought was formatted for Mac. It says that in order for me to reformat, I have to restore my iPod in iTunes but since it isn't recognized my my computer or iTunes, I can't do it.
Suggestions anyone?Hello there, HateKnuckle.
The following Knowledge Base article offers a pretty thorough step-by-step for troubleshooting your issue:

We have a Windows XP desktop with iTunes for windows. The hard drive needs to be reformatted. Right now, the computer will not connect to other computers on the network. Can I save my iTunes songs to a thumbdrive, then re-load after reformatting? How do I do it?
Copy the entire iTunes folder out to the drive. If it is too big to go as one copy stuff over to another computer in batches. It is important to have not only the media but the library file in order to properly restore your library.
See also this User Tip. Assuming the machine won't connect to the internet you could download the SyncToy installer on another machine and then transfer it with the thumb drive. If it will connect to the net don't forget to deauthorize the machine before reformatting the hard drive.

After performing a clean install on a stock apple 1TB fusion Hard Drive it appears as things got reversed and showing my startup as not using the SSD portion. The SSD portion of the fusion drive used to be on top in disk utility, now its on the bottom. It also appears that I have to many partitions. Im thinking i need to reformat my Hard Drive again. I can't seem to find any answers.

According to your descriptioin, I don't think this is system problem, it should be Intel driver problem. It would be contact Intel to confirm this issue whether this is their driver problem.

Disk repair failed / should I reformat my drive / how to format and restore
I have a MacBook Pro late 2011 model and upgraded to Yosemite. The performance on my MB is ok, but just out of curiousity I ran a disk verify, and was told I needed to reboot, hold down CMD / R and run disk repair. I did so and the repair failed. I was promoted to backup and reformat/restore.
Now, I do backup everything using time machine (not sure though if Parallels image is backed up). I do not however have any install disks for Mac OS.
My questions:
1. Should I even bother reformatting my HD?
2. How do I go about formatting the HD and then re-installing the OS and all of my apps, particularly given that I have no DVD
Any thoughts are appreciated. Thank youIf you have extra external HDD, make clone backup with Carbon Copy Cloner or SuperDuper!, then,
1) boot from external clone backup drive.
2) reformat internal HDD.
3) restore from clone backup drive with Carbon Copy Cloner or SuperDuper!. -
Greeting,
I want to reformat my external hard drive using Mac OS Extended (Journaled, Encrypted ) but before formatting it, I want to make sure that if I loose the hard drive or the hard drive get stolen, no one will be able to retrieve or recover the information on it so could you tell me what kind of encryption will be used or is there any way to recover the information?
Thanks!I think FileVault is used to encryp internal hard drive but I wanna encrypt an external hard drive with Mac OS Extended Journaled Encrypted which is completely different!

I am new to Imac. I want to use an external hard drive to backup to but the drive shows very little free space when in fact it is empty. Do I need to reformat it and, if so How? Thanks
What is the external disk?
Is it new? If so, maybe it has a Windows file system on it (FAT, exFAT, or NTFS). If so then reformat to "HFS+ Journaled".
What backup utility are you using? TimeMachine, Carbon Copy Cloner, SuperDuper, etc...? If the external is suppose to be bootable because you are using a cloning backup (CCC or SuperDuper), then it is also important that the disk partition table be GUID.
You can find out this information via Applications -> Utilities -> Disk Utility, select the disk (not volume on the disk) and the partition time will be shown at the botton of the window. Now Select the volume and it will tell you how the file system on the disk is formatted.
Also do you want to leave room for a recovery partition on the external disk? Then repartition it with a small (2GB) partition that can hold a bootable recovery partition that you can setup via the Apple "Recovery Disk Assistant" which can be downloaded from Apple. -
I just had to reformat the external hard drive that houses my iPhoto library, then restore it from a backup. Now Time Machine is telling me my backup hard drive suddenly does not have the space to complete a backup. I also noticed when I go in to Time Machine, there are only about 5 backups recorded on the ext. hard drive. There were many more before. Any idea what happened and if I have to buy a new back up hard drive?
Hallo Kieth ,
I am not quite ready to restore the full iphoto library , as I have days of work re - imputting titles,descriptions and enhancement . I hope that your suggestion works , as I use my Macbook basically to work with digital photography. Through time , I will need to delete my library to recover more disc space and I would hate to have to spend more time re - imputting titles and descriptions all over again .
Thanks for your interest and advice.

Hey guys, I need some serious help. I have an external hard drive, iomega which apears to no longer work; I am sure it is something I have done and I cant figure out what! I am certainly not a computer expert and am in Turkey so I dont have access to a MAC store for assistance or anything like it. Yesterday I plugged my external hard drive into my MacBook and got a message telling me to refotmat. I looked up how to do so and through disk utilities thought I did it right. Now when I plug in the hard drive my laptop does not pick it up; the only place it shows up is in utilities, the same place I tried to repair and reformat. When I am utilities it looks like I have 2 hard drives, one under the other. One tells me the description of the hard drive, the other doesnt really tell me anything. So I erased both of them and I think that is where my problem is. Any help on how I could fix this? I tried to "mount" the one that is not "mounted but it didnt work....I dont even know what that means!!! Help!
When you erased the disk did you select Mac OS Extended Journaled as the format option?

What steps to take to preserve iTunes data when reformatting computer?
I have iTunes for my iPhone and connected to an Apple TV and an AirPlay speaker. My computer, a Windows 7 machine, is getting glitchy and I want to reformat and reinstall the operating system.
I want to know what I should do to back up my Apple data before I reformat.
I don't have any itunes music purchases
I have some podcasts
I have some paid apps on the phone
My entire mp3 collection is stored on a separate drive, just linked to iTunes
What should I do to
Ensure that I have all of my apps and podcasts when I reinstall iTunes on my computer?
Preserve my phone backups that iTunes does?
Is there anything else I need to think about before reformatting?
Thanks!Do the same thing you would do with any other data you wish to preserve on the computer, back it up..
What works best for me is creating a complete image of the drive as it exists currently to an external drive. Then once the computer has been formated and reloaded I can put the content I want and need back on the new drive from the backup. The advantage is I know exactly where the data belongs based off that backup image. -
there seems to be problems with Yosemite and boot camp assistant
i'm cross posting this to the iMac forum but I spent hours online with apple tech today and none of the several foks I talked to there had even seen a 5k 27" yet and my call back from Cupertino and engineering is no till tomorrow so I thought I should post here too
MMy bto 5k shipped from China sunday night and arrived in Maine this morning.... Amazing when you think about it for a bto
iinstallation and set up we're going fine and I started up boot camp assistant to create a temp boot camp while I wait for my thunder bay 4 box to take the drives for my old Mac pro when boot camp will have a1 tera SSD all to itself....
so carved off a 700 gig boot camp partition which the assistant formatted fat I then plugged is the lighting to FW adapter in a LaCie 2 tera fw 800 drive to act as a bridge to my LaCie DVD burner which uses the old fw400 cables and inserted my new shrink wrap win 8.1 retail 64 DVD and up comes the win 8 install in very tiny type in a tiny window which got a bit of a laugh out of me.
And I go through it to the point of selecting that boot camp partition and then said it could not use a fat partition and I should reformat it from the win 8.1 installer which I did and then it said it could not use and unknown partition so I said great and booted back to 10-10 and the boot camp tool to put things back and it said it could not I then went to disk tools and it also said the 3tera fusion could not be either reformatted or put back to a single partition I was on with tech support where I went up through 4 levels of support due to the 5k bto which most had no knowledge of. We tried the optioncommand r to get to DT and the same problem as did going to reinstall from the net which after a 30 min down load could not reformat either it is now kicked to Cupertino with a call back tomorrow
( At this point all I want to do is put the computer back in the condition it was in when i started with a plain Yosemite on an unpartitioned 3 tera fusion... Then deal with boot camp when it can have its own drive)
am betting it will take a Unix comand line to reformat but be aware there may be boot camp issues with my configuration
and any help here will be great fully receivedTry booting into Internet recovery mode, ⌘⌥R, launch Disk Utility to erase the HD. If successful, reinstall the OS. If not, then return it (14 days with no questions asked) and get another machine. Apple sells it and they should know how to fix it.
