I have an external hard drive that is about one third full. Can I now partition it into 2 partitions in which the existing data is in Partition 1, and Partition 2 is empty and available for new, different data?

I have a bad hard drive. I am now booting up from an external HD(passport) and all seems to be going well.I have another external HD (G drive) connected running time machine.
Can take my backed up data from the time machine external HD (G drive), and send it to the Passport and get all my files and programs back?Or will an external Time Machine drive only back up to the macs internal drive?
I have a 4TB internal drive in my Powermac. It currently has two partitions: one that is about 270GB that is almost full, and one that is 3.7GB, that is about 25% full.
Disk Utility will not let me add a third one, however. The drive is NOT a fusion drive.
How do I partition my external hard drive without losing the data already on it? I've been using it with Time Machine on my old computer, but want to use it as a regular drag-and-drop type back up on my new computer. Is there any way to basically split the hard drive so I can still access the Time Machine backups on my old computer, but also be able to use it with my new mac?

I am having problems ejecting the external hard drive that I use to back up my laptop. It is a 2012 MacBook Pro running Mountain Lion OSX 10.8.5. My external hard drive is a WD 2 TB My Book Studio. I use it to back up my laptop with Time Machine. Every time I try to eject my disk now I am told that "The disk (Diskname) wasn't ejected because one or more programs may be using it." I have tried some solutions like to stop Spotlight from indexing the disk and to try and turn off TimeMachine, but neither of these worked. The only thing that has worked so far is to log out of my user name and log back in with a guest user and eject it from there. This takes up a lot of time and is ultimately not really a sustainable way of working on my computer.

Mac Mini running 10.8.5. Time Machine will not back up brand new OWC MiniStack external HD. I've trashed TM prefs, reformatted the TM drive, verified that there are no exclusions, but it won't back up the external HD which contains only data files -- no system, no applications. TM does back up the internal HD.

I tried initiating the Time Machine again but failed. I decided to get a new bigger external drive to use for Time Machine. When trying to eject the external drive I was using it gives me this message:
Would it be safe just to force eject or log out and then log back in again to eject it so I can use my new external drive?

I have a Hitachi Touro USB 3.0 1TB external hard drive that has always worked on my Macbook. Formatted in FAT so it would work on both my PC and Mac. I can't remember exactly when it stopped working, but I think I had to reset my mac once as it stopped responding and the HDD was plugged in. After that it stopped showing up in Finder, but still appears in Disk Utility. It also shows up in Storage under "About This Mac". I've tried resetting my computer, ran Apple Hardware Test, and have tested the hard drive on other computers and it works fine. Just doesn't show up in Finder on my mac!!

I am about to upgrade to Mavericks now
my External Seagate Hard drive just changed to read only on its own?
I went to get info and scrolled down to the Sharing and Permissions
But there is nothing there but a greyed out : You can only read
There are No boxes to check or uncheck, No options to change to read and write, No name of owner or ignore ownership box. NOTHING ELSE IS THERE
I have recently upgraded to Mountain Lion and am having other problems as well
I replaced a 1 TB external drive partiotioned in 2 with a 3 TB extrnal drive run/store my corbon copy cloner back up and time machine.
The 3 TB drive was successfully partitioned through the disk utility and both back ups are installed and the initial back up is complete.
My question is about the 1 TB drive. I want to completely erase all data from the drive in order to use it for a different use.
Using disk utility one of the partitions deleted without incident when following the same protocol the second partition produced error messages.
Volume erase failed
Volume Erase failed with the error:
Couldn’t unmount disk.
If I try to eject the disk
It says it will not eject becaus e a program may be using it...
The only program that utilized this partition is Carbon Copy Cloner which is not being utilized on the new 3TB drive.
I do not see where there is a option to have more than on disk chosen for this purpose so am unsure why the disk utility is seeing the old partion as still in use.
Since the harddrive of my IMac was full, I added an external harddrive to the system for my photos. I use another external harddrive for time machine back-ups (backing up both the IMac and external harddrive with my iPhoto libraries). Recently the EHD with my photo libraries crashed. I now want to restore it from time machine onto a new external harddrive, but am not quite sure how to do this.

View 1 Replies View RelatedI am running an early 08 MBP w/os10.7.3.I really screwed up this morning with a backup disk. my backup system consists of several external, stand alone drives and a HD dock and several internal HDs that plug into that dock.I had a stand alone Iomega/200G/USB that i wiped to give my son who doesn't "get" backups yet. I simultaneously had the USB dock plugged in w/ a Samsung 1.5TB HD powered on. I had moved the Iomega data to the Samsung prior to erasing the Iomega w/ Disk Utility. I had chosen the 7pass wipe on the iomega last night following the data transfer. it had completed 2 passes this morning w/ fourteen hours still showing til completion. i decided that three was plenty and disconnected the iomega to reconnect and select the 3 pass option to expedite. USB dock w/Samsung still powered on and plugged into MBP. disk utility defaulted to the samsung when iomega was ejected. I hit the three pass option and started the wipe without seeing Disk Utility default to the samsung. I did immediately see the flashing red data transfer light on the dock come on and realized my mistake. Immediately disconnected the USB HD dock. Disk Utility was showing "preparing disk" in its status bar. It appears that the formatting has been wiped as reconnecting the dock gives me a "the disk is not readable by this computer". I'm sure the data is still there, but the disk needs to be reformatted. The disk appears in the disk utility sidebar. all disk repair options are greyed out.
I am considering using partition in Disk Utility as that would reformat the samsung disk. However, the data on the disk would normally appear as a blue segment on the rectangular disk setup diagram. there is no blue. According to partition docs, you can partition a disk w/out the data being wiped. However, if the disk is unreadable when the partition process starts, will it wipe all the data as it partitions and reformats? Very reluctant to initiate this process w/out knowing more.

Since I activated FileVault 2 on my Mac boot drive without initializing it, I'd assume that the same thing could be done for any other drive. I've got some external drives with hundreds of GB of data which I'd like to encrypt. Disk Utility lets do it by erasing the drive and encrypting the data written afterwards.
Is there any hidden feature that allows one to convert the drive without erasing it first, like the FileVault utility did for the boot drive (even when working on it!)?

Time machine reported an error and couldn't back up, so I ran disk utility on the time machine drive and got this message.

Then I hit verify disk and got the message

I have a 500GB external HD but a 250HD on my macbook. is it possible to partition the HD 300GB for time machine and 200 for storage of data and files? If so, how would I go about doing that? I just don't want to waste a 500 GB external if my HD is only 250GB.

Bought a used 4 TB Seagate drive, formatted it , checked the speed 150 MB/s read/write and made a partition. Apparently it worked perfect.
However after this first partition the drive is behaving erratically. I can not modify partitions anymore nor delete them. Repair disk is not finding any problem either from the system or from the recovery partition.
I am starting to believe the disk is damaged. Beside the partition problem the disk is behaving fine.

I have a 3 TB hard drive which I'd previously partitioned into a 1 TB and a 2 TB partition. I've emptied and erased the 2 TB compartment, but when I go to the partition section on Disk Utility, and select that partition (now called Free Space) and select it, only the + button is alive, and the - button is greyed out.
How can I delete this entire partition?

I have Windows 7 installed on my sons MacBook Pro.
The Drive is partitioned at 500GB for Windows and 300GB for Mac.
In windows, I need to shrink the Windows drive, and then create 2 extra drives from it.
However, I can shrink the drive, but when I try to Format, it tells me that it cannot find the drive, and then it changes the drive types to all "Dynamic" including the Mac Drive.
And once this happens, I can no longer access the Mac drive during Boot, and windows will not load, as it cannot find the drive during windows boot up. And which point, I have to restore the system and it takes up to 6 hours to installed Lion, as my Internet is slowing that a cold winters day.
So, my question is the following.
How can I successfully shrink the drive.
Then Partition the FREE space
Then Format to NTFS without loosing drive type and integrity?

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 tried to install Ubuntu (don't ask me why) onto my G5 dual core 2.5 Ghz PowerPC and after the installation not working as I had hoped (it worked fine on my netbook btw) I switched off the mac using a hard-shutdown from the power button as the whole system became completely unresponsive. I then tried to reboot and found that on my reboot rather than booting into the user screen as per usual I got the dreaded "circle with a cross through it". After fiddling about with a hell of alot of boot options I managed to get into the open firmware (option,o,f) terminal style screen up. from this screen it would seem that on my internal hard drive that pretty much all of my files are still on the hard drive. As I couldn't open them from the open firmware I was then told by a friend that I could run disk utility from the install cd provided with mac os x and I managed to find my internal hard drive using disk utility.
It seems as though during the ubuntu install I've deleted all partitions on the hard drive and therefore on the "partition" section under "current" it has no partitions set up and I have the option to set one up. It also gives me various different formating options; Mac os x Extended, Mac os x Extended (journalled), Mac os x Extended (Case sensitive journalled), Mac os x Extended (Case sensitive), unix file system and free space. I think it was originally on Mac os x Extended (journaled) but I'm not certain. Before I hit that re-partition button do u think that this is the right thing to do and if so which formatting option should I use? Presuming that the re-partitioning goes well, will I then have to re-install os x? Also will I loose all the data on the hard drive? Although I have the vast majority backed up there are still a few odd files that I wouldn't mind keeping if at all possible and obviously I didn't think to back up those hundreds of apps I've acquired over the years.

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!
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.
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 recently purchased a 120gb SSD to put in my mac mini. In preparation for this, I created a second partition on my drive as a data drive where I will store things in order to make a time machine backup with the 120gb drive. Everything went as planned, except now, I cannot expand my data partition to use the whole disk. Below is a screen capture of what I'm talking about:
To accomplish putting my OS on only 120GB of hard drive, I've made symbolic links for most of the folders in my ~/ folder
This is what the ~/ Folder looks like on my Macintosh HD partition
This is where these files are actually located
As far as I can gather, the only way I can combine these partitions now is to re-format the entire drive, which as you can see would cause me many problems. How to expand a partition "upwards" for lack of a better term? I'm fairly new to Mac.
